High speed SPI display with digital I2C touchscreen driver.
Single-touch capacitive touch bonded on top.
240x320 resolution, 18-bit GPU, 262, 000 color - our library uses 16 bit color mode. Ili9341 (data sheet) controller with built in video ram buffer.
We also have a touch screen library that detects x, Y and Z (pressure) and example Code to demonstrate all of it. The Code is written for arduino but can be easily ported to your favorite controller.
Works with any classic arduino '328. Solder closed three jumpers to use the icsp header for use with leonardo or Mega! 2.8" diagonal color touchscreen TFT.
Touchscreen controller requires I2C pins sda and Sca. Microsd pin requires digital #4.
That means you can use digital pins 2, 3, 5, 6, 7, 8 and analog 0-5. Pin 4 is available If not using the MicroSD.
