Over there a  programmer has created a custom front panel UI for the Feeltech unit ,
The new code is  flashed to the display/control board memory with an St-link programmer ,                                                                                                                                 
The pc based program is connected via usb  and gives remote control of all functions on the front panel  plus adds a cal page  and allows compatible arb wave file upload .

I got stuck in and flashed one of my two units over to help pick up some of the bugs .
