Hi all.? A belated Happy New Year.
There's been quite a few requests for help with the TFT for the V6, the ones available in the wild are hit and miss.? I've now got 5 of the 2.8 TFT obtained from 3 vendors over the last year or so.? They seem to be the worst thing out at raising ones blood pressure with frustration trying to get them to operate correctly.? Of the original 3 only 2 will ok correctly with the Blue Pill yet all of them are fine with a Teensy 3.2.
I have also been watching with interest progress of the code for the V5 and then the V6 with a view to upgrading my early V3, more frustration with both types of display.? The TFT would be a great addition, so that's the way I'm going,? hence ordering some new versions. I've spent a troubled few days trying to coax one of the TFT's no go, the code assembles loads correctly,the display is wired up ok, I know it functions with the Blue Pill so back to basics.
I tested the TFT with a level converter, easy to do and magically it functions. So her's my thoughts to share with others it may help. You can find the schematic here??/g/BITX20/files/V6%20TFT%20Adapter
This is intended hopefully to assist with the problems encountered when trying to obtain a suitable TFT to use with the Ubitx V6 code.? Very many of these displays available from China are advertised as 3.3/5v (operation ?), they will run with either a? 3.3 or 5v supply but will only work with 3.3v logic signals. When wired as in V6, and running the code, the display will show only a blank white screen.

The idea is that this should act as an interface directly between the lead from the raduino and the actual display in use, no messing about with your Raduino.
Hope this is helpful to someone.
