ADC同步采样问题。

在使用CubeMX生成一个ADC采样程序。芯片为STM32H743.使用的开发板为野火的繁星电机开发板。
ADC1和ADC2实现同步，全部是通道2.
ADC3 为独立实现。ADC3的通道为0-10.
但是生成程序，并添加一下使能代码之后，         ADC_Enable(&hadc1);
   HAL_ADCEx_MultiModeStart_DMA(&hadc1,(uint32_t*)&ADC12_CoveredValue,1);
         HAL_ADC_Start(&hadc1);
         ADC_Enable(&hadc2);
         HAL_ADC_Start(&hadc2);
         ADC_Enable(&hadc3);
         HAL_ADC_Start_DMA(&hadc3,(uint32_t *)ADC3_Value,11);
         HAL_ADC_Start(&hadc3);
进行程序运行之后发现主函数里面的while部分未运行，且进入硬件错误判断函数voidError_Handler(void)。该程序在未添加ADC12的采样时，ADC3是能够正常的采样以及对采样结果赋值的且不会进入硬件判断错误函数。当前问题为实现仿真之后，程序ADC123，DR寄存器均存在值，DMA序列计数也均正常，传递目标数组和变量也存在值。但是不能够实现下列程序中的循环赋值，用以实现状态机的状态选择。

同步指什么

tpgf 发表于 2022-9-1 08:43

硬件上是如何连接的呢

aoyi 发表于 2022-9-1 09:04

能成功初始化吗

nawu 发表于 2022-9-1 09:26

三者会不会互相干扰了啊

zljiu 发表于 2022-9-1 09:34

会不会是因为采样速度过快导致的呢

gwsan 发表于 2022-9-1 12:38

相应的引脚进行初始化了没有

tfqi 发表于 2022-9-1 17:56

三个通道采样都打到同步吗

heweibig 发表于 2022-9-1 21:33

同步是什么意思？

koala889 发表于 2022-9-2 20:29

代码好长啊
