In searching for tft displays, i noticed there were serial and parallel. The ones with connectors on the top and bottom are generally pin compatible with uno and atmega2560.? I have several of these and the 3.5" just plugged and Jacks display worked great.. These were mci friends type marked on the board. My other tft's were 2.8 inch.
One i had to change some text size for the display to look correct. The other 2.8 from elegoo was also mcufriend, but Jacks display code worked with no changes.
His code is able to identify several tft drivers and select the correct one.. Very cool.
The serial type tft usually have single set of pins - 8-10 pins. The usually say spi or serial in the description.
I see that some Japanese and Russian hams use these type.
Looking forward to Jack"s next code run...

My PCB uses the Mega 2560 Pro Mini because of its smaller footprint. I buy from Wideenm991 on eBay.
The DDS module is a type II, as shown here:
but are getting hard to find. I can't find the guy who made an adapter board for a Type I to a Type II board (K5ESS??). He sells the adapter for about $2. My board looks like this:
You can see where the DDS and Mega boards go. The advantage of the board is that most of the I/O pins are brought out at the bottom and top of the baord for additional hacking. With the schematic I posted earlier today you should be able to "fit" things on the board.

I bought TFTs with the double connector on the
Right Hand side, to fit Mega 2560.
But some use the single pin headers across the
top and botom (Horz) of the Mega 2560?
I got confused over Mega 2560 compatibility?

I've
had some setbacks at home, but am still trying to get things
going. I don't really use "buttons" on my display, as I am
not using a touch screen at this time. The mcufriend
displays should plug right into a standard Mega 2560 or my
TFT PCB. I should have the VFO working this weekend. The
schematic for my PCB is attached. You'll need the same
pinouts for my code to work with the display.

I bought 2
nice displays on eBay. 3.2"
2-3 days
Fun Invested.? Very complicated and confusing.?
Parts of Demos worked others did not.
I could
not even understand people trying to help me on
the arduino forum.
Buy what
Jack says "MCUFriend" Library compatible, that is
what he is using.? Make sure you get pin
arrangement he is using.
I DIDN'T!
Sad........

Steve ,
There are
few in the works.
W8TEE , Jack is working on some code.
He has the display done. So many are waiting for
his code.? A very talented coder.
There are
some Russian and other hams from Japan with some
. Both are on youtube
PD8W also
has developed some code.
Nice display. Unfortunately he has not finished
the code and cant seem to contact him.
I played with it and the display on the tft was
very nice and the code for display works fine
with my tft's and atmega2560.
Unfortunately the buttons to control other
options need work.
