used sdk : 5.4.7mcu : stm32f446redual motorIn function R3_2_CurrentReadingCalibration has below code: pHandle->PhaseAOffset >>= 3; pHandle->PhaseBOffset >>= 3; pHandle->PhaseCOffset >>= 3;But NB_CONVERSIONS is defined 16u, So is it true the right cod...

I created the WB project from the application type of custom.I used the embedded PGA to measure the current of three phase.But the ADC channel of phase W is disabled.I checked the example project of B-G431B-ESC1, the ADC channel of phase W is enabled...

I buy some chips marked STM32F446RCT6 which flash size should be 256KB.But when I connect it use STLINK, I found the real flash size is 512KB.I have save some data after the address 256KB successfully. And I can read out these data.Am I buy fake chip...

Hi, do you slove your problem? I have designed a custom board from the prototype of B-G431B-ESC1.When I start the motor, it is also very easy to jump to R3_2_BRK2_IRQHandler.
