如題:
HAL_StatusTypeDef HAL_ADC_PollForConversion(ADC_HandleTypeDef* hadc)
{
uint32_t count = 0;
assert_param(IS_ADC_ALL_INSTANCE(hadc->Instansce));
while (1)
{
if (HAL_IS_BIT_SET(hadc->Instance->IF, ADC_IF_ADC))
{
count++;
__HAL_ADC_CLEAR_FLAG(hadc, ADC_IF_ADC);
if(count == 4)
{
break;
}
}
}
return HAL_OK;
}
