ADC同步采样问题。
邱春园 提问时间: 2023-07-21 21:12:53 / 未解决|
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void
Error_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。
下列为代码：
