Adafruit 2.4" LCD on BeagleBone Blue

Adafruit 2.4" LCD

Required components

Steps

  1. Solder across Adafruit 2.4" TFT Breakout IM1/IM2/IM3 jumpers: SPI Mode Jumpers

  2. Solder the two (2) JST SH 6 Wire Assemblies to the Adafruit 2.4" TFT Breakout with: Solder connections from JST headers to TFT JST connector example

    JST Pin TFT Pin
    1-1 GND
    1-2 Vin
    1-3 MOSI
    1-4 MISO
    1-5 CLK
    1-6 CS
    2-3 D/C
    2-4 RST
  3. Connect JST-1 to S1.1 connector on BeagleBone Blue.

  4. Connect JST-2 to GP0 connector on BeagleBone Blue.

  5. Boot BeagleBone Blue using 2016-11-06 or newer image from https://beagleboard.org/latest-images.

  6. Run the blue_adafruit24_setup.sh script below to create /dev/fb0.

  7. See any of the many tutorials on using a raw framebuffer (/dev/fb0) in Linux. As an example, I did 'cat /dev/random > /dev/fb0':
