Why are the timer bus and timer clock different? (F446RE)

2022-08-29
HelloI'm using timers with DMA and I was asking myself of the use of having different clocks for timer clock and timer bus. For example timer 2 has a 90 MHz clock and a 45 Mhz bus. What would be the limitations of the bus?

Repetition of arbitrary waveform through DMA (Problem)

2022-08-22
Hi, I created a program that should create repetition on an arbitrary waveform through DMA burst feature. I use circular mode and I decide to stop it when the repetition are done. I use the transfer complet interrupt to increment a variable to have t...

Bug at the beginning of waveform (DMA transfer)

2022-07-25
Hi I'm trying to generate a signal with 100 ns time on and 100 ns time off thanks to DMA transfer. My problem is that I have a peak of tension before and I don't know what is it (F446RE)Here is my code:int main (void) {     /*Clock and Power initial...

Is there a way for DMA to start to read a buffer in a x position of the array?

2022-07-18
In my current project I am using DMA multi transfer to generate an arbitrary waveform by changing synchronously timers' registers. The first waveform is named "Chrono1", and I would like to interrupt (external) this waveform and insert a second arbit...

How can I read a DMA memory buffer n consecutive times? F446RE

2022-07-08
Hi evryone,I try to find a way to read a DMA memory buffer n consecutive times but the issue is that there is a normal mode (1 time) and a circular mode (unlimited time)I would like to find a way to end the circular mode when I decide, for example to...
