Hello, I’m a bit new to microcontroller programming. I want to implement full speed 12Mb/s usb protocol to send messages back and forth from/to my pc using usbc port on stm32h503rb nucleio board. I tried following serval videos on how to implement th...

I am trying to toggle PB6 gpio at 10MHz on the nucleo board. I am trying to use timers to do this. Using LL library with full optimization and 250MHz system clock rate. I was able to get 3.5MHz ish. With timer 1 prescaler and divider being 0. Please ...

I’m currently using LL library with Irq only containing about one line of code which is: GPIOC->ODR ^=1<<10; I’m using this method to see what’s the fastest rate my irq could be called back. I’m using -Ofast optimization

For the stuff I’m doing, I would need to toggle it in a ISR at the end of the timer’s count(or similar which ever is faster). Doing it in a loop I was able to get around 60MHz. I’m more looking for on how to make the timer interrupt callback faster. ...

I’m trying implement custom protocol and not able to use DMA to do this. I’ve also tried writing to gpio register directly to try reach this rate but not too successful.
