The figure shows that the analog ADC has two functions: Touch Screen and general ADC. Int_tc and int_adc can be generated respectively. The ADC module has a total of eight channels for analog signal input, ain0, ain1, ain2, ain3, ym, YP, XM, and XP are selected through an 8-way analog switch MUX. Set the value of the pre-divider in the control register (adccon) t

There are projects that need to use Silabs's c8051f850. In fact, the most important is to fancy the price, as well as its working temperature. So we need to start learning this film. The simplest ADC routines are as follows:Initializes the system clock, initializes the IO, and so on. The P1.0 is led output and the P1.2 is the ADC input. The ADC uses VDD and GND a

First Glimpse of ZigBeeTo add a smoke sensor module to the ZigBee network, a cc2530 ADC is required to sample the analog signal output from the sensor. The following is a procedure for implementing an external voltage acquisition using an ADC of the CC2530.The following is the configuration of the ADC:1#include 2#include"adc.h"3#include"uart.h"4#include 5#include

The entire concept of Software Defined Network (SDN) is about abstracting hardware to enable new types of network streams. Although many early discussions on SDN are concentrated on routers and switches, SDN does not stop here. SDN has many functions, including helping WCO and application delivery controller (ADC) businesses. Recently, network vendor Riverbed has joined the web content optimization market with its Stingray product series, which also i

In Adccon, the last 0 bits and 1 bits are mutually exclusive.If the 1-bit option is 1, the 0-bit value is not valid.The 0-bit value is valid if the 1-bit option is 0.When 1 bits of 1 are selected: This is the application layer of the program#if adstart==0void Niuniu (void){Uart_init ();Adc_init ();Beeper_init ();Adc_read ();while (1){Itoa (Adc_read ());if (Adc_read () > 2500){Beeper_on ();}Else{Beeper_off ();}Delay (10000);}}#endifNote here that the while loop must have Adc_read () above it, and

few microcontrollers include a DAC. Although you can easily find a inexpensive DAC to control from your microcontroller, you can use, unused peripherals inste Ad of adding parts. Fortunately, you can convert a microcontroller ' s ADC channel along with a GPIO (general-purpose input/output) pin to a D AC. You can make a DAC by charging a capacitor to an analog level by driving it high. You can also discharge the capacitor by driving it's voltage by tri

The ADCTSC registers are shared between the ADC Driver and the touch-screen driver. How can one register be used when processing them? -- Linux general technology-Linux programming and kernel information. The following is a detailed description. You guys give me directions I wrote an ADC digital-to-analog conversion driver for the embedded linux test chamber, but I found that my

Normal through the file system access to the value of Ain serial port, you can use Fread and other file IO read/sys/bus/iio/devices/iio:device0/in_voltage*_raw content. But this requires high frequency access to the ADC is very inefficient, the data needs to be copied from the disk to the kernel process space, and then copied to the user process space, consuming unnecessary resources. This problem can be solved by memory innuendo, Mmap can realize the

ExampleThe order of the ADC1 rule channels is CH0,CH1,CH2,CH3,Do not start scan mode:In one-time conversion mode:Start ADC1, then1. Start converting CH1 (First channel of ADC_SQR)Stop when the conversion is complete, wait for the ADC to start the next time, and continue to convert from the first stepIn Continuous conversion mode:Start ADC1, then1. Start converting CH0 (First channel of ADC_SQR)Go back to the first step after the conversion is complete

DSP Basic Learning-ADC Synchronous samplingPeng2015-04-28 20:31:06In the DSP28027 Lauchpad learning process, the difference between synchronous sampling and sequential sampling of the ADC is a little bit of a study, here the main focus on the ADC synchronous sampling, ADC synchronous sampling has two different actual s

What can I do for someone else? This is a question I have been thinking about lately.Looking at the ADC Power monitoring code, I feel that the understanding of the ADC is not in place, there are many parts of the code do not understand. Such as:1. Why is the pin set to output when initializing?2. What value does the ADC collect, and what is the range?3. Why do I

The 10-bit or 12-bit CMOS analog to digital converter (ADC) comprises of 10-channel analog inputs. It convertsThe analog input signal into 10-bit or 12-bit binary digital codes at a maximum conversion rate of 1 MSPs5 MHz A/D converter clock. A/D converter operates with On-Chip sample-and-hold function. ADC supports lowPower mode.Touch screen interface can control input pads (XP, XM, YP, and ym) to obtain x/

Assuming an existing set of Sigma-delta ADC output sequences, two methods for calculating the corresponding Snr are described below. The CIW window command where data is exported by cadence is: ocprint (? Output "Export directory/output file name" V ("/Saved circuit node"? Resultsdir "cadence Emulation Data Catalog/PSF"? Result "" Tran-tran ")? From the start time to the cut-off time? Step Step).Method One:The first method is to use the He Lenian "ana

The 1.stm32 uses a successive approximation analog digital approach, so what is successive approximation?The successive approximation is similar to the dichotomy, taking the 8-bit data as an example; When an analog amount is entered, the first half of the 8 digits, i.e. 1000 0000, is compared with the analog value, then becomes 1, less than the next bit; set the next one to 1, then compare, greater than 0, and less than the same. Until the two numbers are not large, stop comparing and output the
