Posted on May 17, 2011 at 12:35I don't used ADC interrupt by EOC flag. How to set register?
my program is
#include // Include STM32 header file
int adc_val=0;
void ADC_IRQHandler(void)
{
if(ADC1->SR & 0x02)
{
adc_val = ADC1->DR;
GPIOC->ODR ^= (1<
}
}
void adc_setup()
{
RCC->APB2ENR |=(1<
GPIOC->CRL &= (0xFFF0FFFF); // Clear bit CNF4[1:0]=00,
// MODE4[1:0]=00==> Input Analog
// Set PC4 Input Analog mode
ADC1->SMPR1 |= (0x03<
ADC1->CR1 |= (1<
ADC1->CR2 |= 0x01; // Set bit ADON at first time
ADC1->CR2 |=(1<
while(ADC1->CR2 &(1<
ADC1->CR2 |=(1<
while(ADC1->CR2 &(1<
}
int main()
{
while(1)
{
ADC1->SQR3 &= 0xE0; // Ensure Clear old channel
ADC1->SQR3 |= 14; // Set channel
ADC1->CR2 |= 0x01; // Set bit ADON
..................
..................
}
}
my program is not jump to ISR ADC_IRQHandler when EOC bit is set some one help me answer how to set it.
