写一个STM32单片机DMA配置程序

好的，以下是配置STM32单片机DMA的代码：

#include "stm32f1xx_hal.h"

#define DMA_BUFFER_SIZE 256

uint16_t buffer[DMA_BUFFER_SIZE];

void configure_DMA(void)
{
DMA_HandleTypeDef dma_handle;

__HAL_RCC_DMA1_CLK_ENABLE();

dma_handle.Instance = DMA1_Channel1;
dma_handle.Init.Direction = DMA_PERIPH_TO_MEMORY;
dma_handle.Init.PeriphInc = DMA_PINC_DISABLE;
dma_handle.Init.MemInc = DMA_MINC_ENABLE;
dma_handle.Init.PeriphDataAlignment = DMA_PDATAALIGN_HALFWORD;
dma_handle.Init.MemDataAlignment = DMA_MDATAALIGN_HALFWORD;
dma_handle.Init.Mode = DMA_CIRCULAR;
dma_handle.Init.Priority = DMA_PRIORITY_HIGH;

HAL_DMA_Init(&dma_handle);

__HAL_LINKDMA(&adc_handle, DMA_Handle, dma_handle);

HAL_DMA_Start(&dma_handle, (uint32_t)&ADC1->DR, (uint32_t)buffer, DMA_BUFFER_SIZE);
}

这样就配置好了STM32单片机的DMA。注意，这只是一个简单的示例，实际应用中需要根据具体需求进行配置。
