上面是ADC部分的主要代码，仿真时ADC3和ADC4读出来的数据都是adc3的值。 HAL_ADC_ConfigChannel(&AdcHandle, &sConfig);这个函数不起作用。 仿真进入该函数 if (ADC_IS_CONVERSION_ONGOING_REGULAR(hadc) != RESET) { /* Update ADC state machine to error */ SET_BIT(hadc->State, HAL_ADC_STATE_ERROR_CONFIG); /* Process unlocked */ __HAL_UNLOCK(hadc); return HAL_ERROR; } 由于这个返回错误，没有执行后面切换通道的赋值。 对于ADC_IS_CONVERSION_ONGOING_REGULAR(hadc)函数不是很理解。 请大神帮忙看下需要怎么修改，谢谢。

虽然都知道标准库好用，但是HAL更通用。
