Library to drive an ILI9225 2.2" SPI TFT.
Dependents: ILI9225_TFT_Sample
ILI9225 SPI TFT Library
This library works with the ILI9225 based 2.2" 176x220 TFT LCD shields commonly found on eBay. Note that there is a commonly available 2.2" 240x320 TFT module very similar in appearance but using the ILI9341 driver. (Only the main Buffer IC and I/O pins are different)
