我用2.0库，为什么 identifier "DMA1_Channel1" is undefined

只看该作者 · 2009-4-10 18:02

    DMA_DeInit(DMA1_Channel1);
凡是遇到DMA1_Channel1 都是找不到，我是参考2.0库ADC转换例子

下边是例子
void adc_init_Configuration(void)
{
    GPIO_adc_Configuration();
   // DMA 通道1配置
    RCC_AHBPeriphClockCmd(RCC_AHBPeriph_DMA1, ENABLE);                        // 使能DMA的时钟
