1. ADC采集比较简单，内部的10位的ADC，AIN0-AIN3的输入，主要是用的CSL的库函数#include <csl_adc.h>
Uint32 adc_sample_value = 0;Uint16 samplestoraage[2]={0,0};unsigned char adc_value_baiwei = 0;unsigned char adc_value_shiwei = 0;unsigned char adc_value_gewei = 0;int sysclkdiv=2,convratediv=0,sampletimediv=79;int counter=0,index=0;int channel=1,samplenumber=2;/* Initialize CSL library - This is REQUIRED !!! *//*初始化CSL库*/CSL_init();/*设置系统的运行速度为140MHz*/PLL_config(&myConfig); ADC_setFreq(sysclkdiv,convratediv,sampletimediv);ADC_read(channel,samplestoraage,samplenumber);adc_sample_value = (samplestoraage[0] + samplestoraage[1])/2;adc_sample_value = (adc_sample_value * 330)/1024;adc_value_baiwei = adc_sample_value/100; //ADC电压值个位adc_value_shiwei = adc_sample_value%100/10; //ADC电压值小数点后一位adc_value_gewei = adc_sample_value%10;//ADC电压值小数点后两位
