24 Bit - Performance Characteristics of Analog-to-digital Converter Ad7787 and Problems Needing Atte
24 Bit - Performance Characteristics of Analog-to-digital Converter Ad7787 and Problems Needing Atte
1. OverviewAd7787 is a low-power, low-noise, dual channel, 24 bit, low-frequency measurement system launched by Adi company - Analog to digital converter. It uses the on-chip clock circuit to work, so there is no need for users to provide clock source. The data output rate of ad7787 can be set by software, which makes its conversion rate change between 9.5hz and 120Hz. The chip adopts 10 pin MSOP package, which is very suitable for portable instruments, temperature measurement, sensor measurement, weighing instrument, etc. requiring high resolution and low power consumption.The main features of ad7787 are as follows: it can work within the voltage range of 2.5V 5.25V. The maximum operating current in normal mode is 75 A. 1 in power down mode A the peak to peak resolution at 22 bit effective resolution is 19.5 bits; internal nonlinearity: 3.5ppm; it has 50Hz and 60Hz synchronous suppression function; it has internal clock oscillator and VDD monitoring channel; embedded rail to rail input buffer; with three wire serial interface, compatible with SPI, QSPI, microwire and DSP; the operating temperature range is - 40 105 .2. Pin arrangement and functionThe pin arrangement of ad7787 is shown in Figure 1.3. Working principleThe internal structure and function block diagram of ad7787 is shown in Figure 2. It integrates a - Modulator, a buffer and an on-chip digital filter. The main function of digital filter is to provide normal mode suppression. It can provide synchronous suppression of 50Hz and 60Hz at the default conversion rate of 16.6hz. The ad7787 uses an internal clock circuit, so there is no need for an external clock source. The clock frequency is divided by 2, 4 and 8 factors and applied to modulators and filters, so as to reduce the power consumption of the chip. When using 5V single power supply, buffer enable and clock working at the maximum rate, the maximum power consumption current of ad7787 is only 160 AThe ad7787 has five on-chip registers: communication register, status register, mode register, filter register and data register. All the setting and control of ad7787 are realized through these registers.Ad7787 has three working modes: single conversion mode, continuous conversion mode and continuous mode.3.1 single conversion modeThe conversion timing in single conversion mode is shown in Figure 3. In this mode, the ad7787 is placed in off mode during conversion. Single conversion initialization can be realized by setting MD1 position 1 and md0 position 0 of the mode register. When the ad7787 is powered on, it first performs single conversion mode and then returns to off mode. This conversion requires 2 ADC clock cycles. After the conversion, dout / RDY becomes low. When the data word is read from the data register, dout / RDY becomes high. If CS is low, dout / RDY will remain high until another conversion is initialized and completed. In fact, if necessary, even if dout / RDY has become high, the data register can be read several times.3.2 continuous conversion modeFig. 4 shows the timing of the continuous conversion mode. This is the power on default mode. During continuous conversion of ad7787, the RDY pin in the status register becomes low after each conversion. If CS is low, the dout / RDY line will also become low after the conversion is completed. The user can explain that the next operation is to read the data register by writing to the communication register. Once the SCLK pulse is applied to the ADC, the digital conversion is placed on the dout / RDY pin. During read conversion, dout / RDY will return to high level. If necessary, the user can read the register several times, but must ensure that the data register is not accessed before the next conversion is completed, otherwise the new conversion word will be lost.3.3 continuous reading modeThe conversion timing in continuous read mode is shown in Figure 5. In this mode, after the user writes 001111xx to the communication register, the system can automatically place the 24 bit word on the dout / RDY line after the conversion is completed by providing the appropriate number of SCLK cycles for the ADC. This is more advanced than writing to the communication register after each conversion.In fact, when dout / RDY goes low indicating the end of conversion, the system must provide sufficient SCLK cycles to the ADC and place the data conversion on the dout / RDY line. When the conversion result is read out, dout / RDY returns to the high level until the next conversion starts. In this mode, the user can only read the data, and must ensure that the data word is read before the end of the next conversion. If the user does not read the data before the end of the next conversion, or the ad7787 does not have enough time to read, the serial output register will be reset at the end of the next conversion and save the new conversion result. The continuous read mode can be exited by writing 001110xx instruction to the communication register when the RDY pin becomes low. In continuous read mode, if the ADC monitor is activated on the din line, it will receive a command to exit continuous read mode. In addition, if 32 consecutive ones appear on the din line, the ADC resets and the din remains low until the instruction is written to the chip again.4. Problems needing attention in application4.1 analog input channelThe absolute input voltage range of ad7787 in buffer mode is limited to GND 100mV vdd-100mv, so the common mode voltage must be set carefully to avoid exceeding the limit and reducing the linearity and noise performance of ad7787; The absolute input voltage range in non buffered mode is gnd-100mv VDD 30mV. At this time, small true bipolar signals to ground cannot be monitored. It should also be noted that the unbuffered input channel provides a dynamic load to the drive source. Therefore, the resistance / capacitance connected to the input pin will cause DC gain error, which depends on the output impedance of the driving ADC input source.4.2 reference inputWhen applying the reference input, it should be noted that a high impedance dynamic load may be generated due to the reference input. Therefore, the resistance / capacitance connected to the input pin may also cause DC gain error, which depends on the output impedance of the driving reference input source. In addition, since the output impedance of the recommended reference voltage source is low, the decoupling capacitor should be connected to the refin pin and should not introduce gain error to the system. The reference input voltage obtained through the external resistance means that the reference input can be regarded as a large external source impedance, so it is not recommended to connect an external decoupling device on the refin pin for this type of circuit configuration.4.3 grounding and wiringThe ad7787 can suppress noise interference better than the traditional high-resolution converter. Its digital filter can suppress the broadband noise on the power supply voltage and remove the noise from analog input and reference input. However, due to the high resolution and low noise of ad7787, the ground wire and wiring should be designed reasonably.When designing the ad7787 printed circuit board, the analog part and the digital part shall be separated and limited to the area determined in the board. At the same time, the GND pin of ad7787 shall be connected to the agnd of the system. In any wiring layer, the user must pay attention to the current flow in the system to ensure that the return path of all currents is as close as possible to the path they take to reach the destination, so as to avoid digital current flowing through the agnd part in the board.In order to prevent noise coupling, a layer of ground wire shall be laid below the layer where ad7787 is located. In addition, in order to reduce the impedance of the power line and reduce the interference effect of the power line, the power line of ad7787 should be widened as much as possible. Fast conversion signals (such as clock signals) must be digitally shielded to avoid radiating noise to other parts of the board. In addition, mutual interference between digital signals and analog signals shall be avoided. Do not route at right angles on different adjacent layers to avoid feedthrough noise.When using high-resolution ADC, the decoupling design of power supply and ground is very important. For this reason, the power supply VDD shall adopt capacitor bypass technology and adopt 0.1 F and connect the corresponding power supply and ground in the shortest possible path, so that the high-frequency components can be bypassed. At the same time, one 10 should be connected in parallel F tantalum capacitor bypass low frequency component. All logic chips shall pass 0.1 F ceramic capacitor to decouple.5. Application circuitIn battery monitoring, it is usually necessary to measure the current and voltage of the battery. The specific monitoring circuit is shown in Figure 6. In the figure, the current flows through a 100 resistor, whose value varies from - 200A to 2000a. The measurement of this current can be realized through the direct connection between ain1 channel and shunt resistance. The variation range of battery voltage is 12V 42V, and the peak voltage is 60V. This voltage can be attenuated by using an external resistance network before it is applied to the ad7787. Because the ad7787 itself has a buffer, users can directly connect the ain2 channel with the high impedance attenuator circuit without worrying about introducing gain error.
Manufacture of Toxic Gas Monitor Based on Internet of Things
Manufacture of Toxic Gas Monitor Based on Internet of Things
Step 1: implement with hardwarePart of the project is mainly handled by the MediaTek linkit one committee.The MediaTek linkit one board is connected with gas sensors, namely grove LPG sensor and grove air quality sensor. The sensor readings will be sent to the ubidots server.In the picture, you can see more gas sensors, such as mq-7, mq-135 and mq-138.However, the linkit one board has only three analog pins. A0, A1 and A2, so up to 3 sensors can be connected.Because the output of the gas sensor is analog voltage, and our board is a digital system (microcontroller).We need to convert analog voltage to digital value. This can be done by using an on-board 10 bit ADC.More information about ADC and gas sensor will be described later.Step 2: ADC analog to digital conversionADC represents analog-to-digital conversion, and the equipment performing the conversion is called analog-to-digital converter.The most widely used ADC chips are ADC0804 and ADC0808 of Texas Instruments (TI).Why do we need ADC?The world we live in is simulated, that is, everything is continuous in time. In order to make these analog signals compatible with digital devices such as microcontrollers, these controllers can only understand digital signals, such as' 0's and '1's.Therefore, in order to convert analog signals to digital form, we need to use ADC.How to perform a / D conversion?Converting an analog signal to digital form involves two steps-1) SamplingSampling means dividing the signal into smaller time slots. For example, if we have a sine wave with a continuous frequency in the time domain, we will sample it, that is, we will obtain the amplitude value of the sine wave at a certain equal time interval, so it looks a bit like the picture2) QuantificationThe second step is to quantify the obtained amplitude value. As with sampling, the amplitude obtained can be any irrational value, such as pi (22 / 7) or 1.33333 or sq.root (2), etc/ p》These values will never terminate, so if you want to store them, they will require an unlimited amount of memorySo we need to round the number to the nearest position.This completes the A / D conversion section.But is this just theory?How to actually execute ADC?The answer is by using an IC such as ADC0804 or ADC0808.The latest microcontroller series such as Arduino and AVR, linkit one, has an on-board ADC, which we will use in our project.Step 3: use linkit one onboard ADCA linkit board has three analog input pins, which means that up to three analog devices can be connected to the board.The word ADC resolution is also important.The onboard ADC has a 10 bit resolution, which means that the input analog voltage will be represented by values in the range of 0-1023, i.e. a total of 1024 valuesHow do I get it?It's simple. A 10 bit ADC means that we will get a 10 bit digital value. That is, 2 ^ 10 = 1024 values.In the decimal range, it will be 0 to 1023.How does it assign numeric values?For an analog input voltage of 0V, we will obtain the corresponding digital value of 0. Analog input voltage, i.e. 5V, we will get the maximum digital value, i.e. 1023.Any analog input voltage between 0v-5v will have a digital value between 0 and 1023.This is the formulaADC reading = (1024 * analog input voltage) / 5So, as you can see, for 0V, you'll get 1024 when the ADC reads 5V (actually 1023, because you start counting from 0 here.)Step 4: gas sensors: how do they work?There are many types of gas sensors. They are classified according to the way gases are detected in the atmosphere.1) Electrochemical typeThe MQ sensor family falls into the following categories: gas sensors. These gas sensors have sensing elements usually made of SnO2 or tin oxide (IV), which is the correct IUPAC name (International Federation of pure and Applied Chemistry) or commonly referred to as tin oxide (not Satan IC).SnO2 layer isIn this case, this phenomenon is called adsorption, which is very different from. This ceramic matrix is usually made of alumina (Al2O3). Absorption.Absorption is a surface phenomenon, which means that gas molecules only accumulate on the surface of SnO2 layer.To increase the adsorption rate, we need heating elements. This is done through the heating coil (wire mesh) on the MQ gas sensor.Heating can increase the adsorption rate. There is a specific pre heating time for each sensor before use.As the gas molecules begin to gather on the surface, we get a voltage proportional to the concentration as the outputThis is the voltage we will measure to detect the gas.Now, due to adsorption, that is, molecules accumulate on the sensing elements of the sensors, these sensors become useless after a few months and need to be replaced with new sensors. You cannot clean the sensor because everything happens at the molecular level.These are the most widely used and available sensors for electronics enthusiasts.In addition to these sensors, we have four other types2) Infrared3) Infrared imaging4) Semiconductor and5) HolographyNow, if you see any MQ gas sensor, it will have 6 pins, 4 for heating purposes and 2 for output voltage and ground.In the picture, you can see the 6 pins of mq-8 gas sensor.The second picture shows the mq-8 gas sensor which is highly sensitive to H2. It can also be used for the detection of liquefied petroleum gas.For reference, I attach this data sheet. It is clear from the data sheet that multiple types of gases can be detected using a single mq-8 sensor.Before continuing, I suggest you read how the gas sensors of the engineer's garage and seeed studio work and how to select gas sensors.Step 5: hardware requirementsTransmitter sideMediaTek linkit one boardGrove air quality sensorGrove LPG sensor ClickSoftware / servicesUbidotsStep 6: register on ubidotsThe first step is to create a free ubidots account!!Ubidots is the cloud service provider we will use.You are free to use any other service.If you re-use other services.Please go to http://www.ubidots.comRegister on the website.Then follow the instructions in the picture.Or follow the instructions below-1) Register on ubidots2) Click the symbol in the upper right corner to add a new source.3) Name your source, such as Intel Edison, Arduino, etc.4) Click source to add a new variable5) Select the type of variable as the meter and set the minimum and maximum limits6) Note the variable ID of each variable you create.7) Now go to your profile and write down the token ID in the API key.Please note that the pictures are from my other projects. Everything remains the same, except that you need to specify a different name and select the display type accordingly.Note the variable ID and auth. Token number. You must enter them in the program.Everyone's numbers are different. Do not copy the image.Step 7: transmitterGrove LPG sensor is connected to A0 pin and grove air quality sensor is connected to A1 pin of mediak linkit one board.The analysisread() function performs the necessary analog-to-digital conversion.The digital value obtained is between 0-1023 (1024 in total) because the resolution of the ADC is 10 bits.Use formulaReading% = (ADC reading / 1024) * 100The program for the transmitter is written in Arduino ide with. Ino files attached.Remember to make the following changes in your code.1) WiFi AP name2) WiFi password4) Token ID, and then upload the code to your development board.Step 8: TestThis is a short video of my general screen, showing you how the meter reading changes when any sensor value changes.For demonstration purposes, I connect A0 and A1 pins directly to the 3.3V and 5V pins on the board.Note: you can also see these values on the Arduino serial monitor as long as the development board is connected to the computer via USB. After removing the USB and using battery power, it will not print values in the serial monitor.

In order to get started with your business plan, you should know what it is that you are going to do and how you will do it.Most of the time it is hard to make sense of what someone means when they say that something is bad. There are two main reasons for this. The first is that people don't really understand what they are saying. The second is that people think that because they have some sort of control over what they say, they can use it to mean something other than what they actually mean. This type of argument is also known as a mis-quotation.The reason why you need to use an acer laptop is because you don't know how to fix your computer. And there are so many different types of computers that are used in the world today.

Application and Technical Index of LED Full Color Display Screen
Application and Technical Index of LED Full Color Display Screen
Since this year, the market demand for LED full-color large screen has shown a rapid upward trend. Just after the Spring Festival, large projects began bidding. In April and may, despite the impact of SARS, it only delayed the implementation plan, not cancelled the project. After SARS, many projects have been stepped up. The contract amount of major LED large screen manufacturers increased by 20% compared with the same period last year, and some even almost doubled compared with last year. There are many new companies entering the field of full-color large screen, and their achievements are also excellent. Compared with previous years, the market sprouted early this year, with many large projects, and more than a dozen projects with more than 10 million yuan have been implemented. In the third quarter, many major projects entered the bidding stage. Another feature is the significant increase in projects invested by enterprises, including applications in commercial advertising. It can be said that led large screen, as a commercial advertising media, has been favored by the advertising industry again after nearly ten years of silence. At the same time, the export situation of full-color screens is also encouraging. In early September, the annual optical Expo was held in Shenzhen. This exhibition is a big exhibition of LED industry in the past year. LED large screen, LED lighting, LED traffic lights, LED production equipment, testing equipment and other dazzling, indicating that the new climax of China's LED industry has come. The author believes that this exhibition is a sign that China's LED industry has reached a turning point of localization. Internationally renowned LED light-emitting tube manufacturers and screen manufacturers have also begun to transfer to mainland China on a large scale. Mainland China will become the manufacturer of LED and its productsManufacturing center. Broad market, good investment environment and low labor cost make China gradually become the manufacturing center of the world's electronic industry. Just like computers, mobile phones, televisions and other electronic products, China is also the manufacturing center of LED large screen industry.As a scientific and technological worker who has been engaged in the research and development of LED large screen for a long time, the author has always paid attention to the development of LED large screen in China and the new achievements of international large screen display industry. Three years ago, in the article on the development of LED large screen, the author talked about several application fields and characteristics of LED large screen in China, and proposed that full-color large screen is mainly an image project in China. It should be said that this general pattern has not changed, but the increasing demand for commercial advertising is also a very important development trend. It can be said that China's LED full-color large screen industry is ushering in a new climax. Seriously studying the new situation of market development and technological progress, taking correct countermeasures, seizing opportunities, rapid improvement and sustainable development should be worthy of study by peers. Here, I venture to raise questions about technical indicators and hope that peers and experts will correct me.Image engineering: Aiming at the international first-class level. Image engineering means that the main purpose of building a large screen is to add style to the city or a major event. It does not directly create economic benefits, but it can enhance the city's popularity, shape the city's image, improve the investment environment and create a business atmosphere, which is conducive to economic development and good social benefits, so as to indirectly create economic benefits. Image engineering is mainly government investment, focusing on social benefits, rather than or mainly obtaining economic benefits through commercial operation. In recent years, the large LED screen of large squares in urban central areas or citizen leisure squares built in many parts of the country is a typical image project. A large number of LED displays in stadiums and gymnasiums are necessary supporting facilities for modern stadiums and gymnasiums, which also belong to this category.Since it is an image project, it is bound to pursue the perfect performance and effect as much as possible, especially high-quality video images. Generally speaking, it is to make a giant color TV, which has been worked hard by many domestic manufacturers for a long time, and has made considerable progress, but it is still far from our ideal goal, and there is still a big gap compared with foreign full-color large screens.At the beginning of this year, the commercial street of Hunan Road in Nanjing invested heavily in the construction of a full-color large screen with an area of 114 square meters. The screen was built by UNITEK company in the UK and has been running for more than half a year. From the effect, it can be called the best large screen in China. The author participated in the formulation of the technical indicators of the screen and the final acceptance test, and felt that many aspects were worthy of learning and imitation by domestic peers.As a large full-color screen, its key technical indicators include: high enough brightness, viewing distance and viewing angle; Good color reduction; Sufficiently high grayscale capability; High enough scan refresh rate. High enough video signal processing capability, especially good consistency, structure and technology. The technical indicators set by Hunan Road Daping during bidding are:The white balance brightness is greater than 5000 CD / m2;White balance color temperature 6500k;The number of video processing bits is greater than 10bit;The gray level of each primary color is greater than 10bit, which can display 1.07 billion colors;Refresh frequency is greater than 400Hz;The display screen has no perceptible color difference, and the color difference of each primary color of the full screen is less than 4nm;There is no perceptible brightness difference on the display screen, and the brightness difference of adjacent pixels is less than 5%. There is no perceptible mosaic when displaying monochrome gray images of red, green and blue;MTBF is greater than 5000 hours and MTTR is less than 30 minutes;Objectively speaking, not only at that time, but also today, the products of domestic manufacturers have not been fully achieved. In many cases, due to the improvement of the level of LED, the brightness of the normally designed large screen is no longer a problem and can meet the requirements. However, brightness is only an important indicator, not all. Now we generally feel that the large screen brightness of domestic manufacturers is more than enough and the softness is insufficient. The overall effect is not as good as that of foreign well-known manufacturers. The reason is that there are more technical problems that have not been solved. The author believes that from a technical point of view, it is necessary to make efforts in the following aspects.(1) Color matching and blendingThe large screen is composed of a large number of light-emitting diodes. The photoelectric parameters of the light-emitting diodes must be designed, calculated and tested in order to achieve a good white balance. Simple estimation and judgment with the naked eye can not have good results. This involves the selection and driving design of LED, which not only affects the photoelectric performance of the screen, but also affects the reliability. Especially in the design of indoor full-color screen, thermal design should be paid enough attention, otherwise the effect and reliability will be a problem.
