答案对人有帮助，有参考价值 0 GD32F405VG 调试过程关于DAC/DMA/TIMER等问题的解决 GD32F405与STM32F405外设完全兼容，外设的地址映射也是完全兼容。ST的标准库中的名字与GD32的外设名字不一致，比如STM32中的TIMER1的地址映射，对应的是GD32的TIMER0，STM32的DAC1对应GD32的DAC0，等等诸如此类。 STM32F405的程序直接烧写到GD32F405中，程序能够运行但部分功能异常，在STM32F405中使用TIMER6触发DAC1转换，使用DAC1的数字量通过DMA传输，程序一切正常，但是GD32运行此程序，DAC无波形产生，DAC的DMA全传输完成中断无法进入，最后发现问题所在： STM32中配置的TIMER6对应GD32的TIMER5（暂时还是称作TIMER6），但是TIMER6始终无法触发DAC产生波形，开启TIMER6的更新中断，DEBUG模式，程序可以进入TIMER6的更新中断，DAC依然没有模拟量输出，最后抱着试一试的心态使用TIMER5触发DAC，DAC波形出现，但是DMA依然无法正常运行，刚开始认为是硬件配置有问题，最后发现是初始化顺序有问题，DAC_OUT_INIT();后面增添了一段是DAC缓慢输出到所需电压的一段代码，没有此代码时，DMA运行正常，加上此代码段后，DMA不运行，原来是DAC外设初始化后紧接着初始化了DAC的DMA功能，最后使能了DAC输出以及DAC_DMACmd(DAC_Channel_1, ENABLE)就是这一句DAC_DMACmd(DAC_Channel_1, ENABLE)使能早了，如果没有Init_Laser()这一句，使能后没有问题，有了Init_Laser()这一句，DAC的DMA功能使能了但是DMA相应的通道没有使能，使程序异常。运行不正常的代码如下： //DAC初始化配置 void DAC_OUT_Init(void) { GPIO_InitTypeDef GPIO_InitStructure; DAC_InitTypeDef DAC_InitStructure; DMA_InitTypeDef DMA_InitStructure; TIM_TimeBaseInitTypeDef TIM_TimeBaseStructure; NVIC_InitTypeDef NVIC_InitStructure; RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_DMA1, ENABLE);

从DAC_OUT_Init();中拿出来，放在Init_Laser();之后，程序运行正常，也就是，DAC初始化完之后没有立马使用DMA传输的话，不要使能DMA传输功能，放在最后使能。能正常运行的代码如下： //DAC初始化配置函数 void DAC_OUT_Init(void) { GPIO_InitTypeDef GPIO_InitStructure; DAC_InitTypeDef DAC_InitStructure;
