I'm wondering whether there is a DMA channel to transfer a received message from the CAN fifo to a memory location. Is it possible at all to get DMA working with the CAN controller?Kind regards,Stefan

Hi,I'm using Timer 3 channel 4 for the PWM output und channel 2/1 as a combined PWM input where channel 2 is the direct input.If I feed the output pwm to the input, I don't get a capture value in CCR2, only in CCR1. Can I use the output and input sim...

Hi,my application is loaded via the bootloader and i sstarted. Two threads are generated and it seems properly generated because one thread is in ready state while the other is in suspended state.Systick is used for the ThreadX and TIM6 is used for t...

I'm running the SBSFU on a STM32H7 where I can succesful upload a new application and it is starting. The application is running on an external flash.The question is, can I simply change the clock system settings to the applications need at startup o...

It seems that CCR2 is counting up to the ARR value set by pwm output and then reset, what I then read out. In this constellation I can only measure signals that have a higher frequency than the current pwm output to not get a higher CCR2 than ARR.Thi...

To answer my own question:The problem was caused by the PendSV handler which was not called of the Threadx source but from the applications interrupt handler. The PendSV handler of Threadx does the scheduling.
