Hi you all,
as a breef summary; I set up a timer to trigger an adc that should than use the DMA to transfer the data to memory, i need 111 samples at a time. Sadly for some reason this only works for one sample so if i check
__HAL_DMA_GET_COUNTER(g_hadc1->DMA_Handle) it will get stuck at 110.
and subsequently my
and subsequently my
HAL_ADC_RegisterCallback(g_hadc1, HAL_ADC_CONVERSION_COMPLETE_CB_ID, ADC_LineScanComplete_Callback); is never called.
Though the timer and ADC for sure triggeres as i can the see the DR register updating its value.
And as far as the reference manual goes (Page 961 DMA One-shot) it should be possible to use
If you need further information I'll happyly provide it !
Greetings
Tan

HAL_ADC_Start_DMA(g_hadc1, (uint32_t*)dest, 111); to get like 111 sequential timer triggered samples, that are transfered to memory via DMA
I tried various combinations of all possible adc settings, and all of them keep beeing stuck on 110 remaining DMA cycles. As well as trying to look up the resgisters for any errors that might have been accured, but i was unable o find anything suspicious.
It just seems that there is like no new DMA request generated after the first one.
For like testing I've chosen a reasonable 5 us cycle time for the timer(though for prodution this would need to go down to ~ 500ns at this point i will prob have to step away from HAL drivers).
But the timers is as far as i am concerned the only viable way of properly time ADC and signalgenerator in the fastes reliable way.
My assumption of the correct config would be

on a LQFP176 Package
Did anyone observe something simelar or has any help at hand ?If you need further information I'll happyly provide it !
