Dear Christophe! Thanks for your support. I have a feeling I am getting closer, but not quite there yet. So I appreciate your time in helping me out. Now I have been able to add the adc io, as in the screenshot you sent using only the cvs code. So I am not mixing anymore ecos-3.0 and the cvs. But when I run the tests on my stm3210e eval board I do not get the desired output. The output of adc2 test is shown below. It shows that no samples have been read. I am also not sure what to make of the \0x09 stuff before the '=' signs.
My goal is to be able to read the value from the potentiometer on the board (http://www.st.com/internet/com/TECHNICAL_RESOURCES/TECHNICAL_LITERATURE/DATA_BRIEF/CD00278458.pdf as shown on page 2/3) and eventually also from the 3 bnc connectors. First of all, how can I know which input (BNC or Potentiometer) is connected to which device on which channel? And secondly why when I try to display values from all channels on both devices I receive nothing. One of these channels must be connected to the potentiometer no? The BNC connectors are currently left open. Hope I can make this work.
