STM32 Beginner: needs help on ADC with STM32F103r8

[Pa.6]

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;

    }

 }

 }

When using as local/auto variables I'd recommend clearing them properly

GPIO_InitTypeDef GPIO_InitStruct ={0};

ADC_InitTypeDef ADC_InitStructure = {0};

>>this is not working

Yeah that's not very enlightening, use the debug step the code, review the settings in side the peripherals, try to understand the mechanics of the failure.
