大家好，我是讯享网，很高兴认识大家。

ST电机库没有带母线电流采样，所以这里提供一种方法添加，如果在生成代码前，那么直接在cubu里加个ADC就好，如果在生成代码后不想改了就用我这种方法。

#include "power_stage_parameters.h" #include "stm32g4xx_hal.h" #include "MC_type.h" #include "regular_conversion_manager.h" #include "r_divider_bus_voltage_sensor.h" #include "bus_voltage_sensor.h" #include "parameters_conversion.h" RDivider_Handle_t *BUS_Curr; uint16_t RealBusCurrSensorFilterBufferM1[6]; RDivider_Handle_t BUS_CurrParamsM1 = { 
    ._Super = { 
    .SensorType = REAL_SENSOR, .ConversionFactor =(uint16_t)3.3,//(uint16_t)(ADC_REFERENCE_VOLTAGE / VBUS_PARTITIONING_FACTOR), }, .VbusRegConv = { 
    .regADC = ADC2, //改成你自己的通道 .channel =MC_ADC_CHANNEL_17, .samplingTime = LL_ADC_SAMPLING_CYCLE(47), }, .LowPassFilterBW = 6, //M1_VBUS_SW_FILTER_BW_FACTOR, .OverVoltageThreshold = 65535,//OVERVOLTAGE_THRESHOLD_d, .UnderVoltageThreshold = 0,//UNDERVOLTAGE_THRESHOLD_d, .aBuffer = RealBusCurrSensorFilterBufferM1, }; void RVBS_CalcAvBusCurr( RDivider_Handle_t * pHandle ) { 
    uint32_t wtemp; uint16_t hAux; uint8_t i; hAux = RCM_ExecRegularConv(pHandle->convHandle); if ( hAux != 0xFFFF ) { 
    pHandle->aBuffer[pHandle->index] = hAux; wtemp = 0; for ( i = 0; i < pHandle->LowPassFilterBW; i++ ) { 
    wtemp += pHandle->aBuffer[i]; } wtemp /= pHandle->LowPassFilterBW; pHandle->_Super.AvBusVoltage_d = ( uint16_t )wtemp; pHandle->_Super.LatestConv = hAux; if ( pHandle->index < pHandle->LowPassFilterBW - 1 ) { 
    pHandle->index++; } else { 
    pHandle->index = 0; } } }

然后初始化一下，在循环里调用RVBS_CalcAvBusCurr就好

讯享网

讯享网 BUS_Curr = &BUS_CurrParamsM1; //初始化 RVBS_Init(BUS_Curr);

当然ADC初始化里和gpio初始化里加入你自己的引脚

在这里插入图片描述
然后就读到原始数据了，做个处理就好
