Setup
Z88DK must be installed to compile the C programs in this repository. See the Z88DK README for details. I use the Snap package local installation approach on a Ubuntu machine.
Run git clone https://github.com/TomAwezome/cerberus2080-c-demos && cd cerberus2080-c-demos to download the demo programs.
Compiling
The programs are written targetting the Z80 processor, memory map, and standard BIOS of the CERBERUS 2080™. To compile program source code, the following command can be used:
zcc +z80 -vn -O3 -startup=0 -clib=new -I.. main.c -o output -create-app
In the above command, main.c is the C source code of the program, and output is the desired name of the resulting program binary. That command will generate a file output.bin, which is the final program binary. If Z88DK was installed using the Snap package, then it may be necessary replace zcc with z88dk.zcc due to Snap package command name prefixing. To see verbose output, replace -vn with -v. If a program requires floating point support, add the -lm flag.
The final program binary can be loaded into the CERBERUS 2080™ at the standard $202 address.
Notes
Programs are tested using paulscottrobson’s CERBERUS 2080™ emulator.
