I try to transplant the Three-Shunt FOC project based on STM32G431RB supported by MCSDK to STM32G431C8.But The ADC interrupt is never called.I comment the code below in function R3_2_ADCxInit,the interrupt works.LL_ADC_INJ_SetQueueMode( ADCx, LL_ADC_...

I've designed an FOC driver borad using STM32F302.The ADC that samples the resistor current is set left-align in the generated code by MotorControl Workbench 5.4.7.Does ADC have to be left-aligned?Due to this,the ADC value is always out of bound

I've designed an FOC board.First of all,I want to realize the SVPWM without using other transformation in order to make the motor rotate first.PWMC_SetPhaseVoltage(pwmcHandle, Valphabeta);so I generate an array about Valphabeta as the code below:#de...

I have designed an FOC driving board using the chip STM32F302K6U6,but I can't find the the chip in the latest version of MCSDK.How can I create an FOC project by the chip?

I just created an STM32F302R8 project by MCSDK,and imitated the configuration and the code.Honestly speaking,I've learned a lot in the process of reading the code step by step.

in fuction R1F30X_GetPhaseCurrents(single shunt,the same as the three shunt code),the code directly read the ADC value which has a 4 bit left-shift,and check saturation.But int16 ranges from -32768 to 32767.The op-amp circuit I design makes sure the ...

Solved.It depends on the ADV_TIM_CLK_MHz.#define ADV_TIM_CLK_MHz 128 #define PWM_FREQUENCY 5000 #define PWM_PERIOD_CYCLES (uint16_t)((ADV_TIM_CLK_MHz*(uint32_t)1000000u/((uint32_t)(PWM_FREQUENCY)))&0xFFFE) and the variable: .hT_Sqrt3 = (P...
