I am trying to implement a simple interrupt routine, blinky led using a timer on the stm32f103 "blue pill" board.
I have been reading the datasheet, reference manual, timer cookbooks and all but I'm not able to figure this part out.
I'm using the gnu-arm cross compiler and was successful in getting a timer a started and was able to blink an led by continuously checking the 'update event' bit inside the TIMx_SR register.
Up till now, I had a look at the NVIC section in reference manual but I can't figure out exactly how to work with the vector table...
Any suggestions or resources are welcome.
