For demonstraiting the LLAPI
This code shows how the LLAPI protocal is read and sent back out. Loading the data and dealing with flags is optional. It is inteneded to be included in to a project looking to comunicate with the Bliss-Box LLAPI.
Two projects use this code thus far. Bliss-Box adaptors found at https://bliss-box.net and the MiSTer core fork that interfaces with the BlisSTer. The MiSTer cores can be found here. https://github.com/MiSTer-LLAPI
Documentation may change so i'll just post a link to the live version. https://bliss-box.net/integration/
The schematics to the BlisSTer board are also included for anyone who wishes to make thier own boareds. Bliss-Box chips can be purchased preflashed from Bliss-Box or use a ATMEGA328 chip and flash the the firmware to it You will lose the update ability). Bliss-Box does not have gerber files as the work was done via the factory.
