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 think that guide is for the Gameduino 1. I developed a library for my 68000, is it possible to use c or c++ for the z80 library? I ported the GD2 library and then made simplified c routines which I can call from a gcc compatible assembler.
It initialise the Gameduino GD.begin, sets a random palette and then puts random points. This is a very simple but powerful way of using the GD. You get a HD graphics adapter with 1mb of frame buffer. Plus it limits the number of SPI commands you need. I used it to create an HD mandelbrot plotter.
