    ADC_SelectConfiguration blocks ability to use ADC

    steve.muller

      This is a continuation of this thread: http://www.cypros.org/?app=forum&id=0&rID=89110  I was able to find an alternative means to work around the problem, but I have again run into this issue.  I've tried all the suggestions in the thread, and nothing has worked.  There seems to be confusion that I am getting faulty values... that isn't the issue.  The issue is when using the ADC to read values after calling ADC_SelectConfiguration(), no values are returned *at all*.  It actually gets caught up in the ADC_IsEndConversion(uint8 retMode) function in the ADC.c file.  The ADC_DEC_SR_REG register never gets set to 1, and so, the function blocks until I quit the program.  It works fine if I never call SelectConfiguration.

         

      Can anyone help me figure out what's going on?  I haven't been able to find this issue anywhere else on the forum.
