termwatch

This watch was made from an Arduino and PiTFT display to have SSH access, control your computer, and give you the time! All CAD files and source code is attached.

Corresponding Arduino to RPi Pinning

• 13 to 23 (SPI_SCLK)
• 12 to 21 (SPI_MISO)
• 11 to 19 (SPI_MOSI)
• 10 to 24 (#SPI_CE0 aka TFT_CS_3V)
• 9 to 22 (GPIO25 aka TFT_DC_3V)
• 8 to 18 (GPIO24 aka RT_INT)
• Scroll Button Arduino D3
• Selector Pin Arduino D4

You will also need to create a voltage dropper to allow the PiTFT to work with Arduino. Layout as so:

Arduino digital pin xx (5V) ------- # -----|4,7k|---- + ----|10k|-----# GND
                                                      |
                                                      |
                                         TFT header input yy (3.3V)

Otherwise you can use this code with any other (ILI9340C or ILI9341) compatible LCD.
