Hi,

I am using the STM32F0Discovery board and I am acquiring ADC converted data value using the DMA. Well, I am able to read values but I cannot understand how the uC fills the Buffer. I am using a buffer[5] because I am acquiring 5 ADC converted value (channel 1, 2, 3 and Vref and Temperature). How can I manage the filling of my buffer? Thanks in advance, Giuseppe. #stm32 #dma #discovery

Hi Clive1,

you are great and right :) In fact, the problem was due to missing call to SystemInit. Now it works fine. Thanks a lot for your excellent and very useful support! PS: I think that if you write a manual for beginner it's a good thing :)

Unfortunately that would be a lot of work, and not pay very well. The topic area is pretty broad and changing. I prefer to swing at pitches here for my own amusement. I'd recommend Joseph Yiu's books on the Cortex-Mx processors as a good starting point and companion to ARM's TRMs. I could probably suggest some more foundational texts, but most are 30+ years old limiting their immediate applicability today.
