Hardware and wiring

this tutorial is basically for running it on a raspberry pi (zero, 1, 2, 3) and a TFT display which matches up with chips like the ones from adafruit. as long as it uses standard spi it should work with the new dtoverlaymodule in the latest jessie versions of raspbian... i think there is no need for a custom kernel. it's just a little bit configuration.

i tested it with following TFT's:

• TFT FeatherWing - 2.4" 320x240 Touchscreen For All Feathers
• Adafruit 2.4" TFT LCD with Touchscreen Breakout w/MicroSD Socket - ILI9341
• adafruit TFT's with ili9341 driver
• pimoroni hyperpixel4

no configuration needed for:

• official raspberry pi 7" display
• any HDMI display
• skip all the TFT setup parts

wiring

• this should explain how to wire up your display

SDO (MISO) TFT Data Out SPI_MISO    = GPIO09
SDI (MOSI) TFT Data In  SPI_MOSI    = GPIO10
SCK TFT Clock           SPI_CLK     = GPIO11

CS TFT Chip Select      SPI_CE0_N   = GPIO08
D/C TFT Data / Command              = GPIO24

RESET Reset                         = GPIO23
 
GND Ground                          = GND
VCC 3V3 supply                      = +3V3 or 5V

• optional if you like to use the included PiButtons script

BUTTON 1    used for restart app    = GPIO19
BUTTON 2    used for shutdown pi    = GPIO26

• give you the option to put some function on a hardware button (like restart the WeatherPiTFT service, shutdown/reboot your Pi, change display brightness, etc.)
• feel free to add your own functions in PiButtons.py
