ADC config with DMA and Timer

Hi,

I want to program STM32F103 in which define an array that is completed with ADC value. I need to trigger the ADC with timer and also use DMA. It means that when the array complete, the DMA_IRQ Handler send this array by USART channel. I wrote this code but it doesn't work.

I would be appreciate if you help me to correct this program.

#include "stm32f10x.h"

#define ADC1_DR_Address    ((uint32_t)0x4001244C)
