Vu2SPF recentlyreleased an article on a project he created for using a tft Touch Control display.
The 2.4 TFT version is available at his Blogsite - http://vu2spf.blogspot.ca/
Full Touch Control
VFO A B M
Tuneable BFO - touch control
Save to EEprom - manually via touch
and much more.....
After reading his blog site I did some quick setups and starting working with VU2SPF, testing etc...
All is progressing very well
We are currently working on a TFT 2.8 version and have just installed it in a bitx
This software is still being developed and not quite ready for release.
A few weeks... before release
The project uses of the shelf items
TFT display - i used a 2.8in tft by elegoo from amazon -very clean and crisp display
SI 5351 DDS -by Addifruit - from amazon $9.00
Atmega 2560 - around $11.00 ebay - this provides lots of rooms for options.
Rotary encoder and buttons if you wish - as it has full touch control -- but options for control buttons.
