There is not information, on how to clear the flag (1 or 0), on register TIMx_SR (x=1,8,20).I believe there were also other registers where it was not mentioned, how to clear them.

Hi,i am testing the ADC at the moment, and the values i get out of it look pretty good. Except, when using a squarewave.See my video: https://www.youtube.com/watch?v=TmKADM2yQvU The manual states for having the ADC run from AHB clock: "... has the ad...

Hi,when investigating issues with the DMA, i found, that the prescaler is not working properly.At 128 and 64 setting, the initialization of the ADC does not even finish. It is stuck in the loop after enabling the ADC. SET_BIT(RCC->AHB2ENR, RCC_AHB2...

I have some problems getting all the information out of the manual.Using HAL is no option.There are a lot of questions (Question are all refering to "Injected simultaneous mode") that cant be answered, or details that are confusing:- When in Injected...

Hi,i am trying to investigate the behaviour of the ADC when measuring a value, where the ADC is triggered from a timer source.In the manual it states, that when the ADC is clocked from SYSCLK or PLL "P", then it would be faster, but when clocked from...

Have you tried searching for a "count" at all? Seems like DMA/ADC is set up for 2 conversions, but you expect 4.

Page 73 says it all. Thats a bit embarrasing 

Now i have finished the research:- It works as in the manual stated.- The results could be quantified.AHB freq is 42.5MHz.The triangular wave is 25kHz with 1% sym. Blue trace is pwm from timer 2 at 170Mhz -> timer tics = adc bits

I found the cause:I had oversampling on. This, the fact, that the Rigol DG800 could not be used as one would need (could not sync anything with the backside plugs - and much more issues), and that the scope also has its capture and processing "rhythm...

Have you set sequence count to 2 in the ADC initialisation (not the DMA)?

Information missing in reference manual for register clearing interrupt status on G431

STMG431 RBT6 - ADC sync does not seem to work as per manual

STM32G431 - ADC wont get ready with 128 and 64 prescaler.

Seting up ADC in dual mode with DMA - Manual is not satisfying.
