I’ve created a chess board computer based on my chess program called Embla.
It consists of:
Raspberry Pi 3
TFT with touch screen
This microcontroller accepts simple commands via its serial interface. E.g. “move e2e4” will make it blink the LEDs at the E2 and the E4 fields. “animate” will make it do an animation (when the board is in idle mode).
3x Adafruit 24-Channel 12-bit PWM LED Driver – TLC5947
64 LEDs (I ordered red LEDs but got white ones)
1 red LED for power status Embla chess program (available for free for Linux, Android, MacOS X and Windows); strength is around 1600 elo
a custom python-script for the user-interface, using PyGame. The scripts speaks the UCI protocol so any other chess program that speaks this protocol will work. I also tried GNU chess for example.
PiTFT – Assembled 320×240 2.8″ TFT+Touchscreen for Raspberry Pi: Is this not the cutest little display for the Raspberry Pi? It features a 2.8″ display with 320×240 16-bit color pixels and a resistive touch overlay. The plate uses the high speed SPI interface on the Pi and can use the mini display as a console, X window port, displaying images or video etc. Best of all it plugs right in on top! Read more.
Adafruit 24-Channel 12-bit PWM LED Driver – SPI Interface – TLC5947: For all of you out there who want to control 24 channels of PWM, we salute you! We also would like you to check out this breakout board for the TLC5947 PWM driver chip. This chip can control 24 separate channels of 12-bit PWM output. Designed (and ideal) for LED control, this board is not good for driving servos. If you need to drive servos, we have a controller for that over here. Read more.
