I am trying to use the subj example sketch with modifications and have run into a problem. I have a new red MCUFRIEND 3.5" TFT ID 0x9486 installed on a Mega2560 board.
I can get the simple button example sketch to compile and work but want to operate in the landscape mode with 4 buttons.
I can move two buttons around in landscape with edits to the up/down tft.initbutton functions.
I can even rename the up/down names to v_tft and t_tft throughout the example sketch.
When I do this the location of the touch sensitive area is no longer associated with the new button locations.
When I attempt to expand this two button sketch to 4 buttons the new sketch will not compile.
I have enclosed my "latest" attempt plus the compiler error listing.
Is there someplace I can find a complete description of the MCUFRIEND library functions ?
What is the purpose of the empty U3 pas group marked W25032 ?
Any help will be greatly appreciated.
