PokittoLib is the library needed for programming the Pokitto DIY game console (www.pokitto.com)
Dependents: YATTT sd_map_test cPong SnowDemo ... more
PokittoLib
Library for programming Pokitto hardware
How to Use
- Import this library to online compiler (see button "import" on the right hand side
- DO NOT import mbed-src anymore, a better version is now included inside PokittoLib
- Change My_settings.h according to your project
- Start coding!
