Co-existance of ADC1 and DMA on STM32G0B1CE

[AWack]

Hi,

I´m running ADC1 (IN1, IN2, IN6, IN7) with DMA process. Everything works fine. But if I try to initialize afterwards the DAC1_OUT1 (normal or DMA - both tried) I get a hard fault. 

Is there a general collision between DAC and ADC or would could be the problem.

Best regards,

There shouldn't be any problems using ADC and DAC and DMA all together. Likely the problem is a bug in the code.

A few ways to tackle the problem:

• Use the hard fault analyzer to see what's going on. Probably a forced error. The address might shed light into why it's occurring.
• Debug the code, see what the call stack is when hard fault is hit.

Hi,

 

I made some further tests and it seams that it is only a problem together with USBPD / TCPP01. But don´t know why...
