The input only limitation on channels 0 and 1 comes from the QC-DAQ adapter. When the adapter is not used (and physically unplugged from the Pipistrello board), the corresponding pins on the Pipistrello can be used as outputs. Do not configure these channels as outputs when the adapter is plugged, as this would cause electrical contention.
