STM32 透過ADC_GetFlagStatus 知道 EOC狀態並讀值

其實網路隨意google一下就很多資料

uint16_t readADC1(void) {  uint16_t value;  //ADC_RegularChannelConfig(ADC1, channel, 1, ADC_SampleTime_55Cycles5); // Start the conversion  ADC_SoftwareStartConvCmd(ADC1, ENABLE);   // Wait until conversion completion  while(ADC_GetFlagStatus(ADC1, ADC_FLAG_EOC) == RESET);  ADC_ClearFlag(ADC1, ADC_FLAG_EOC); // Get the conversion value  value = ADC_GetConversionValue(ADC1);  ADC_SoftwareStartConvCmd(ADC1, DISABLE); return value;}

void AdcPro(void){ static uint16_t buf[SAMP_COUNT]; static uint8_t write; uint32_t sum; uint8_t i; //buf[write] = ADC_GetConversionValue(ADC1); 原本直接讀取資料   buf[write] = readADC1();  if (++write >= SAMP_COUNT) {  write = 0; } sum = 0; for (i = 0; i < SAMP_COUNT; i++) {  sum += buf[i]; } g_usAdcValue = sum / SAMP_COUNT; /* 取平均 */ //ADC_SoftwareStartConvCmd(ADC1, ENABLE); /* 原本先為下次使用而enable */}
