I have tried two tfts with my Chipkt uC32. Both are 40 pin tfts I purchasedoff eBay. I have been attempting to use the UTFT library demos for 240x320 and 400x320. I have attempted to to use a shield and tft from Coldtears http://www.ebay.com/itm/121302118129?_trksid=p2060778.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT and http://www.ebay.com/itm/3-2-inch-480x320-TFT-LCD-module-w-Font-IC-ILI9481-arduino-DUE-MEGA-2-8-3-5-/121097673674?pt=LH_DefaultDomain_0&hash=item1c31fbdbca.

I also have attempted to wire the pins as documented in the UTFT requirements including JP4 adjustment.

Anyone have any suggestions? My project requires at minimum 230x320 resolution. If you have a working solution please provide links to hardware and software libraries.

Thanks, Marty

The simplest solution is to invest in a Picadillo-35T form 4D systems.

I also have a TFT library which supports a number of TFT screens on the PIC32.

https://github.com/TFTLibraries/ https://github.com/TFTFonts

I am in the process of re-writing it and cleaning it up - making it more modular.

https://github.com/MajenkoLibraries/DisplayCore

That version doesn't yet support as many screens, but the ones it does support it does so much better than the other library.

DisplayCore is directly installable from the Plugin Manager of the UECIDE beta version.

Oh, and I've just fired off an eBay order for an ILI9481 based screen. You see them around quite a bit now and I haven't had one to sort out proper support for it - so in about 3 years time when it arrives from China I will be able to write a full DisplayCore driver for it.
