Flipper Game Boy Game Link Cable API

Simple API that can be included in projects to provide a flexible and easy way to handle data exchange over a Game Link Cable.

Current Version: 0.5

Available from: https://github.com/kbembedded/flipper-gblink

Current feature status and future roadmap:

• Ability to use EXT clock source. i.e. connected device drives the clock line
  
• Callback on byte transfer completion
  
• Flexibility in IO pin selection at alloc time
  
• Ability to enable and disable interrupt on input clock
  
• Ability to set timeout in microseconds between clock edges. If exceeded, it is assumed the next clock is the first bit of a byte
• Set a NO_DATA_BYTE pattern. i.e. after a byte transfer is complete, a default byte is prepared to be sent out if no new data is provided before the transfer starts
  
• Supports communication to GBC
• Supports communication to GBA using GBC games
• Supports communication to GB (untested, but should work)
• Supports communication to GBA using GBA games
• Function as INT clock source. i.e. Flipper Zero drives the clock line
  
• Drive clock at varying speeds as GBC supports
• Proper documentation
