I have a project where I need to output a precise waveform to drive some external FETs and thought this would be a good opportunity to fill a DMA buffer with CCR values and tie this to TIM2 that is configured with output capture on channel 1. Just fo...

STM32CubeMX version 6.5 is crashing on Fedora 34. This is also the case for everyone else on my team, who are also using Fedora 34. When it crashes, it also takes out Chrome and VS Code, if they are open. It generally happens when I am selecting diff...

We are in the process of upgrading one of our MCUs from the STM32F072RBT6 to the STM32F303RBT6 and we are experiencing problems with the F303. I am testing out all the firmware using a NUCLEO-F303RE (the 512kB version of the MCU). To further test thi...

I've edited this post to make it more useful to others.We are well into development of a board at work using an STM32F072RBT6 MCU. I just wrote a quick from scratch test using a NUCLEO-F072RB board to verify things. I'm not sure of the exact problem,...

Hello,I have a NUCLEO-H745ZI-Q board that I am trying to configure as a FS USB device setup as a Virtual Port Com. The only changes I have made to the stock CubeMx setup is removing ETH and setting up two encoder inputs on TIM2 and 5. I've tried disa...

Thanks for the reply. I found that SCB-VTOR was not being set anywhere. The following is in system_stm32f3xx.c/* Note: Following vector table addresses must be defined in line with linker configuration. */ /*!< Uncomment the following line i...

Have you called the following?HAL_TIM_IC_Start_IT(&htim1, TIM_CHANNEL_1)Did you generate this code with CubeMx?

The PWM is high on the right side of the cycle. That is a higher CCR corresponds with a longer right sided high. With downcounting and PWM mode 1, you get this, but as you have pointed out, you can't achieve 0% duty cycle in this mode. I suppose I co...

Wow, ok. Thanks for clearly pointing that out. What I am trying to come up with is a native way to perform right edge aligned PWM and this is what I came up with. Any advice on the proper way of doing this would be much appreciated.

OK. So TIM2 I had set for down counting and TIM1 for up counting. The "error" I am seeing is being caused by down counting, but I don't understand why.
