FPGACode-ide -> IceSugar-riscv -> IceSugar-tv80 -> IceSugar-6502
Here you will find a project for IceSugar implementing 6502. 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 up5k_6502 and uart_ice40 and iceZ0mb1e
What is done:
- RAM: SPRAM or BRAM
- ROM: BRAM (TODO: or SPI FLASH)
- UART: Minimal size uart
- SPI: Classic spi
The commands can be executed manually in the terminal as well as through the Task menu in Code
