I'm trying to output a triangular wave, i'm very new to this so let me know if i'm doing anything wrong.
I'm using stm32 f3 discovery board with stm32f303vc, I selected circular mode, started timer 7 with some frequency and update event mode, configured dma with channel 3 so it can go to dac channel 1. I'm trying to lookout for the transfer complete interrupt, when detected i'd like to increment dac channel 2 value. however i'm not sure how to look for the interrupt? i'm using HAL and i looked through the examples but i couldn't find how to enable the appropriate interrupt and how to look for it.
I found a callbackmethod in dac.c that was weak type and i defined that in my main.c file and put a break point in it. but nothing happened i think because i haven't enabled the interrupt.
I was also wondering if circular mode would be appropriate for my needs, is normal mode better for this? but i'm not sure who to trigger the dma manually.
Any links to tutorials and helping material will be very appreciated. Thanks
