ZigBee Tour (vi): Several important CC2430 basic experiments--ADC Single sampling first, the connecting link In wireless sensor networks, it is important to convert the analog value of the sensor to digital to facilitate transmission and processing. ADC (Analog-to-digital Converter) is used to accomplish this conversion. In the previous section, we introduced the serial communication between CC2430 and PC

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/

Transformations can be divided into two groups: regular and injected. A series of transformations in any order on any number of channels constitutes a group conver

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

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

From: http://bbs.ednchina.com/BLOG_ARTICLE_225912.HTM 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 Chan
