When trying to configure the ADC block’s mixer in bypass mode, there is an error being generated saying that the mode/type is not valid. Looking at XRFdc_MixerRangeCheck function in xrfdc_mixer.c, it appears that it is not possible to bypass the mixer without rebuilding base.bit or recompiling xrfdc_mixer.c.

Hi,
What is your problem, what do you want to achieve with the ADC?
I’d like to bypass the mixer in order to collect the raw samples.

Hi,
Did you manage to do this? I would like to do this as well, but can’t figure out the mixer settings.
cheers

It appears that you have to rebuild the bit file selecting the desired settings. The software library (xrfdc) only allows configuring the mixer in certain way. I tried to recompile this library but it does not work with the original bit file.
Fantastic - thanks. I was coming to that conclusion, but it wasn’t clear from the supplied notebook (using ZCU208) and nice to have that confirmed (the doc seems to be a bit thin on some of this fundamental stuff ).
