Well, the new displays arrived today, and seem to have just muddied the waters more.
I think I have solved the communication problems, which were due to my ATMega processor on the WD board needing the "Old Bootloader "  so I have at least been able to upload a sketch to the WD.

On Rx board:
Display is generally white, but can be turned off by pressing the push button, and then will turn on again (blank white) if I touch the display.
Wi-Fi is working and I can ping the board on the network, but despite the webserver being nominally activated, nothing is served

On WD board:
Display flashes white on booting, then goes dark, but there is a little background activity visible.
No obvious response to the push button or touch.

Any suggestions?

Regards

Russell
