ILI9340 SPI TFT Library for Raspberry Pi/Orange Pi
You can show a chart to ILI9340/ILI9341/ILI9163C/ST7735 SPI TFT.
You can choose bmc2835 library/WiringPi(WiringOp) library.
I tested these TFT.
1.44 inch 128x128 ST7735
1.44 inch 128x128 ILI9163C
1.8 inch 128x160 ST7735
2.2 inch 240x320 ILI9340
2.4 inch 240x320 ILI9341
2.4 inch 240x320 ILI9341

| TFT | Rpi/Opi | |
|---|---|---|
| VCC | -- | 3.3V |
| GND | -- | GND |
| CS | -- | Pin#24(SPI CE0) |
| RES | -- | Pin#5(*) |
| D/C | -- | Pin#3(*) |
| MOSI | -- | Pin#19(SPI MOSI) |
| SCK | -- | Pin#23(SPI SCLK) |
| LED | -- | 3.3V |
| MISO | -- | N/C |
(*) You can change any pin.
Note:
Opi have only 1 SPI.
OPi-PC have CE0 and GPIO8.
OPi ZERO have CE1 and GPIO8.
Build using bcm2835 library
RPi Only, Very fast
wget http://www.airspayce.com/mikem/bcm2835/bcm2835-1.56.tar.gz
tar zxvf bcm2835-1.56.tar.gz
cd bcm2835-1.56
./configure
make
sudo make check
sudo make install
* This tool require 1.56 or later.
* Because this tool uses bcm2835_gpio_write.
cd $HOME
git clone https://github.com/nopnop2002/ili9340spi_rpi
cd ili9340spi_rpi
cc -o demo demo.c fontx.c ili9340.c -lbcm2835 -lm -DBCM
Build using WiringPi/WiringOp library
Both of RPi/OPi, But slow
git clone https://github.com/nopnop2002/ili9340spi_rpi
cd ili9340spi_rpi
cc -o demo demo.c fontx.c ili9340.c -lwiringPi -lm -DWPI
This library can use ILI9341 TFT.
From left 2.8" ILI9341,2.4" ILI9341, 2.2" ILI9340.
This library can use ILI9163C/ST7735 TFT.
From left to right.
2.2 inch 240x320 ILI9340
1.44 inch 128x128 ST7735
1.44 inch 128x128 ILI9163C
1.8 inch 128x160 ST7735
A library of XPT2046 Touch Screen is included in this library
