GDay Grogster, All,

Check that the TFT GND pin is actually connected to GND, by adding the switch you ‘may’ have an isolated GND pour meaning that GND on the TFT is at actually system GND.

It is hard to follow the traces with the colour choices but it is basically the same as the original except for the switch and different HC12 layout.

Kind Regards,

Mick (the big one)
