I'm using a STM32F4 and MC SDK 5.4.8 to control a BLDC motor from MAXON, when start the motor without load, the motor can be started everytime, but sometimes it will stucked with a load, the motor control status is still RUN, but the motor will not r...

I'm working on a project whith use a STM32F407 MCU to control a bldc motor and also has a low power mode, the mcu will into stop mode.Now the stop mode is working, and we have issue to control the motor after wake up from stop mode.the code to enter...

Dears，Currently I'm working on a BLDC project, and with the MC SDK, we can control the motor.And we also want to make the MCU(STM32F4) into STOP mode to save some power, the issue is the MCU can not goes into STOP mode, anyone tried this before?The ...

I have a STM32F767 board, and a demo with 10.1 inch display which is working fine without video.And I tried to add only one, like below, and when I download the code into the MCU, it will run into hardware fault.After some debug, I found in:it will n...

Thanks for the informaiton.One last question(maybe stupid as this is the first time to use this STOP mode), let's say we reduce the current for MCU to less than 1ma, but still we need the external power supply to keep the MCU in STOP mode, and curre...

Thanks for the suggestion, I think the issue is from the debug tool.Once I disconnect the debug, with the two lines, it works with the MC init function.Thanks again for the support.

Thanks for your feedback.But I don't think such kind of comments would help, did you checked my code, and the code example from ST with Hal, actually the example you shared is amost the same, difference is I'm using Hal, your are without HAL.it is c...

Thanks for the comments.I understood the last half, but I'm not sure wherther this is usful, because I tired without calling the "MX_MotorControl_Init", then with debug, I can see the MCU in stop mode, and wake up from a hardware pin, with the debug ...

Solved.When I tried this video for a STM32F767 MCU, and I enabled the hardware jpeg, and the generated code will run into hardware fault.in __sti___24_TouchGFXGeneratedHAL_cpp_db822bdb, it will call HardwareMJPEGDecoder::HardwareMJPEGDecoderand then ...
