ChibiOS Free Embedded RTOS

Hi mobifab,
thank you for the additional infos, quite helpful for me to understand the driver code better.

Hi,

now everything is working. I just had to increase the period of the ADC sampling. Not knowing still, why this is necessary.
But I am also still interested in the answers to my above questions.
Thank you.

Here is the current code FYI:

Hi,
my last reply was partly wrong as I have still not found the real bug. The whole program only runs if the DAC conversion routine is not started.
But all the processing is hanging if I uncomment the line SignalGenerator.Start() in main.cpp which will indirectly start the DAC.

So still I am ...

Hi,

thank you for reply. I am not too familiar yet with the details of the drivers for ADC and DAC and with ChibiOS in general. I thought ADC and DAC are sharing
DMA channel 1.
I assumed that because I found in adc_lld.c :

ADCD1.dmastp = STM32_DMA1_STREAM1;

and in dac_lld.c:

DACD1.dma = STM32 ...

Hi,

is there an example for the use of ADC and DAC in parallel on the STM32F0 discovery board. I tried but it seems due to the usage of the same DMA channel this does not work with the current drivers. Or did I miss something ?
Thanks for any hint or example code.
