STM32 Beginner: needs help on ADC with STM32F103r8
Hi,
I am a beginner for stm32. I am using stm32f103r8 , IAR-ARM IDE.
I have attached my celow , this is not working , i am checking it in Proteus 8.8v ( with stm32f103r6). Can anyone help me out with this ?
PROGRAM:
#include "stm32f10x.h"
#include "stm32f10x_adc.h"
void main()
{
RCC_APB2PeriphClockCmd(RCC_APB2Periph_ADC1, ENABLE); //Enable ADC1..//
RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOB, ENABLE);
RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOC, ENABLE); //Enable Port C..//
GPIO_InitTypeDef GPIO_InitStruct;
GPIO_InitStruct.GPIO_Mode = GPIO_Mode_AIN;
GPIO_InitStruct.GPIO_Pin = GPIO_Pin_0;
GPIO_Init(GPIOB, &GPIO_InitStruct);
GPIO_InitStruct.GPIO_Mode = GPIO_Mode_Out_PP;
GPIO_InitStruct.GPIO_Pin = GPIO_Pin_1;
GPIO_InitStruct.GPIO_Speed = GPIO_Speed_50MHz;;
GPIO_Init(GPIOC, &GPIO_InitStruct);
//----------------------------ADC Initialize------------------------------//
ADC_InitTypeDef ADC_InitStructure;
ADC_InitStructure.ADC_ContinuousConvMode = DISABLE;
ADC_InitStructure.ADC_DataAlign = ADC_DataAlign_Right;
ADC_InitStructure.ADC_ExternalTrigConv = DISABLE;
ADC_InitStructure.ADC_ExternalTrigConv = ADC_ExternalTrigConv_None;
ADC_InitStructure.ADC_NbrOfChannel = 1;
ADC_InitStructure.ADC_ScanConvMode = DISABLE;
ADC_Init(ADC1, &ADC_InitStructure);
ADC_Cmd(ADC1, ENABLE);
//----------------------Selecting input Channel--------------------------//
ADC_RegularChannelConfig(ADC1, ADC_Channel_9, 1, ADC_SampleTime_1Cycles5);
//-------------------------Start Conversion------------------------------//
for(;;)
{
ADC_SoftwareStartConvCmd(ADC1, ENABLE);
while(!ADC_GetFlagStatus(ADC1, ADC_FLAG_EOC));
ADC = ADC_GetConversionValue(ADC1);
if(ADC > 500)
{
GPIOC->BSRR = 0X0000000F;
}
else
{
GPIOC->BRR = 0X0000000F;
}
}
}
