I have a motor control board built around the STM32F446RET6. I was updating code using motor control workbench to alter the control parameters.After an update, I was no longer able to use the motor control workbench console to communicate with the bo...

In my application, I am driving a low voltage, low speed PMSM with a custom power electronics board. Using motor control workbench, I have a configuration where I can reliably start the motor and it spins up to speed.However, the reported speed thoru...

I am working with a custom SM-PMSM, and built a motor drive to power it.The motor does not start, and the START-UP FAILURE always occurs. There is a pulse of current delivered to the motor, which I assume is used to orient the rotor.Using the monitor...

So, I tried following the steps my colleague used.I have had no success.He was able to get communication working once, but when changing or adjusting something, the problem seems to reoccur.I tried compiling with low level drivers vs HAL, the code wo...

Yes, thanks, I will see what tools are available I can use.I ask a colleague for help, he just reported that he got the code working.I will go through his steps and see what happens for me.It sounds like it requires the correct version of CubeIDE pai...

Unfortunately, no.I have some older code, that was used to program a Nucleo board in early development.I had communication working on that prototype.I don't know my way around ST code that well.So I am not sure where to look for the MSP files.I do no...

Thanks to both of you for these suggestions.I have found both HAL_UART_MspInit() and HAL_UART_Init() in the file stm32f4xx_hal_uart.cNeither of these files contain code to initialize the GPIOs.Below is the code form HAL_UART_MspInit()I didn't include...

I checked into some of these things as best as I can.First, the UART is set up to be interrupt driven.I checked to see if DMA_Init was run afterwards, and I did not see DMA_InitFor clocks, I started my code generation using motor control workbench. F...
