Connecting the screenkey module to any microcontroller is not quite straight forward. It uses non-standard protocol to control the module.
Following the previous project, the Simple Response Time Game, I decided to built a driver using MSP430F149.
The driver would accept some commands using standard UART protocol and convert the command to screenkey’s protocol.
To test the driver, I hooked it up to PC using XBee Seria- to-USB converter that I purchased from Dontronics.
If anyone interested, I will try to release my screenkey source code.
I may need some time to tidy up the code. 🙂

Sorry, I haven’t been writing this blog. Our first baby girl just arrived few months ago.
Anyway, here is my recent home project.
It’s a simple response time game.
The game rule is:
When the display changes from “Ready” to “Hit”, press the button as quickly as you can.
If you are too slow, you lose!
The button LCD is the RGB24 ScreenKeys, which can be obtained from Sparkfun.
Below is the schematics:
Below is the demonstration video.
Note: it is not easy to play this game while holding the camera. 🙂
