From the project
A very bad example of a Raspberry PI to Jamma adapter
- Description - Bugs and feature requests - Copyright and license
This is a very bad example of a Raspberry PI with 40pin GPIO to JAMMA adapter but it is a Christmas present and free to use.
It uses the VGA666 AD video converter for Video output, an LM4952TS as an audio amplifier (class D) and MCP23017 I2C chip for the JAMMA controls.
Bugs and feature requests will be disabled as this is a bad example. If you want you can use it on your own risk.
