Im trying to get the ADC working on the STM32f2100RB Discovery board. The code keeps getting stuck in the underlined, bold line of code.
****ADC Setup code****
void Config_ADC1DAC1 (void){ //ADC Set-up
GPIOA->CRL|=(0x0000); //Enable GPIOA - Analogue input mode
GPIOB->CRL|=(0x0000);
RCC->APB2ENR|=((0x01<<2) | (0x1<<9)); //Enable ADC1
ADC1->SR&=~0x02; //EOC cleared
ADC1->CR1|=((0x01<<8)); //Scan mode
ADC1->SQR1|=(0x01<<20); //Number of conversions - Two ADC's
ADC1->SQR3|=((0x01<<(5*0))|(0x02<<(5*1))); //PA1, PA2
ADC1->CR2|=((0x01<<0)|(0x01<<1)); //ADC started, EOCS set
***Reading ADC***
ADC1->CR2|=(0x01<<22); //Start a regular group conversion
for(c=0; c<2; c++) //For loop, two ADC's
{
while(!(ADC1->SR&0x02)); //wait for conversion complete
adc_data[c]=(ADC1->DR); //Read data from buffer
}
Can anyone see a problem with the setup code? This works perfectly fine with the STM32f4discovery board (with a few tweeks).
Thanks
Tom
