Debugging Z80 With Arduino
Let’s hook an Arduino up to a 1980s CPU and see what happens!
My aim is to connect an EEPROM to the Z80, put some simple code onto it, and step through the execution cycle by cycle, watching how the Z80 works and matching it to the timing diagrams.
This was inspired by Ben Eater’s 6502 and 8Bit CPU videos, and is what I based my Arduino code on.
