icesugar-z80's Introduction

icesugar-z80

FPGACode-ide -> IceSugar-riscv -> IceSugar-tv80 -> IceSugar-6502

Here you will find a project for IceSugar implementing Z80. As well as full automation of assembly and testing. More detailed documentation on usage in the FPGACode-ide.

This project is based on the developments of iceZ0mb1e and tv80

Distinctive Features:

DMA
IRQ
GPIO
WDT
New version tv80
Clean test project
Embedded toolchain

Other functions:

I2C (software)
SPI (software)
UART
BRAM
SPRAM
