Hello, everyone,
I would like to use the Dazzler 3 with a Z80 processor. For this I built an SPI interface (untested so far). I program the Z80 in assembler and would like to know which SPI commands can be used to address the Gameduino.
Does anyone have any tips for me? I googled and unfortunately couldn't find anything about the command structure of the Dazzler.
I would be grateful for a little help.
Regards
Unilein

Hello everyone, in the meantime I have found this article: excamera.com/sphinx/gameduino/porting.htmlGoogling with the right keywords brings the solution  Does anyone here happen to have an SPI interface for the Z80 or the 6502 as a circuit diagram? I have already built an SPI interface, but somehow I can't get communication with the Gameduino. Thx Unilein

I'm afraid that won't work. The Z80 can only manage 64 KB of memory. A library with its overhead is certainly beyond the possibilities.
If so, then the library must be written directly in machine language. And I would probably be able to do that if I knew something more about the Gameduino.
