I have been working on interfacing the PIC32MX250F128B with a small 2.2" TFT display from Adafruit. It's a nice little display that is fairly easy to communicate with, using SPI communication. The display I'm using is: http://www.adafruit.com/product/1480
Adafruit provides nice open-source libraries for their products. However, they are for Arduino and thus cannot be directly reused for the PIC32. I went through the library and ported it over for the PIC32, in C. I have attached my project file as a .zip file and you can download it to go through the library header and source files, as well as the demo code. I've tried heavily commenting the code so that it is self-explanatory.
As far as hardware goes, with the demo code, the pin connections for the display are provided below. The display interfaces with the PIC32 using SPI, and I clocked the SPI at 20MHz.
BL (backlight): I left it unconnected, but you can connect it to 3.3V for backlight.
SCK: connected to RB14 on the PIC
MISO: left unconnected, since I'm not reading anything from the screen
MOSI: connected to RB11 on the PIC
CS: connected to RB1 on the PIC
SDCS: left unconnected as I'm not using the microSD card for this
RST: connected to RB2 on the PIC
D/C: connected to RB0 on the PIC
VIN: connected to 3.3V supply
GND: connected to gnd
The pins I used are defined in the code and you can easily change them as required.
I used my custom proto-board for testing on a breadboard. You can find details here: http://tahmidmc.blogspot.com/2014/02/pic32-proto-board-details-schematic-pcb.html
This is quite a nice display that is fairly simple to interface with. It can be added to any application now, and with the PIC32 can be used to add a vivid colorful (2^18 colors) display for any application, eg for UI. The resolution of 240x320 means that images will look sharp and crisp at the given screen size.
