  • Word of advice - to get this to work with an Arduino, you will likely have to hand-code an SPI protocol. Luckily, the timing diagram on the User Guide above is very helpful! Here’s a video of the board in action.

  • Could someone kindly post some code that’ll get the SPI on ATMega 328 (on the Arduino Duemilanove) down to 50kHz or lower? As it stands, the ATMega’s SPI’s slowest speed is 250kHz (five times the max speed of the button pad controller), so if you’re planning on getting one of these suckers for use with an Arduino master, I’d suggest you find a fix before dropping 40 American dollars on it…

No public wish lists :(
