Hi Jim, et al,

The remote head is working really fine, but I would like to set TX/RX not only by touching the TFT screen, but also by observing the microphone switch (i.e.: a "0" or a "1"). In the config screen of Quisk there are ample possibilities to use serial data formats, but I wonder if one of the (ODROID XU4) IO's could could be used for that purpose as well (would save me first to encode the state of the PTT and then send it in a serial format).

Much obliged for any suggestions!

I missed the CTS and DSR pins which can be used to activate the PTT, so I guess my question can be considered as "resolved".
