First of all talk about the problem, feel this code Compose Studio is rather strange#include "Tft\tft_driver.h"File not found, unable to openNo include can use functions only under the same projectEach time you run the program results are differentAn example of using an ADC is given below:ADC Initialization function:void Configureadctempsensor (void) {/ * Configure ADC Temp Sensor Channel */ ADC10CTL1 = i

First look at the code that people think is "right" void Myadc_init (void) {//Clock enable Rcc_ahbperiphclockcmd (RCC_AHBPERIPH_GPIOA, enable); Rcc_apb2periphclockcmd (RCC_APB2PERIPH_ADC1, ENABLE); GPIO configuration Gpio_inittypedef PORT_ADC; PORT_ADC.

Each ADC module of stm32 can switch to different input channels and perform conversion through an internal analog multi-channel switch. Stm32 is particularly added to multiple group conversion modes. After the program is configured, It can automatically sample and convert multiple analog channels one by one. There are two ways to divide the conversion group: rule Channel group and injection Channel group. Generally, up to 16 channels can be arranged

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

); determines whether the adswitch is over.Ret = adcdat0 0x3ff;, the value after normal ADC conversion. That's it. It's easy? Okay. You can only say that. Then, makefile: obj-m :=adc.o Then create a makemod. The Code is as follows: make -C /home/eastmoon/work/linux2.6.28/ M=`pwd` modules Then, you only need source makemod to compile it into buzzer. Ko. OK, the driver is like this, and then the application #include Then makefile: CC =

1. Normal converson Mode) The Normal conversion mode (auto_pst = 0, xy_pst = 0) is used for general ADC conversion, such as measuring the battery voltage through ADC. 2. Independent x/y position conversion mode (separate x/y position Conversion Mode) The independent X-axis/Y-axis coordinate conversion mode includes the x-axis mode and Y-axis mode. To obtain the X and Y coordinates, you must first coordinate
