crimbus-lights-z80

A crimbus tree controlled by an emulated Z80.

Installation

1. Wire up a NeoPixel compatible LED strand to D15 on an ESP32.
2. Update config.h's config_ledstrip_LEDCOUNT to match the length of the LED strand.
3. Update config.h's config_wifi_SSID and config_wifi_PASSWORD appropriately.
4. Build, upload code to ESP32.
5. (optional) Set up static DHCP so the ESP32 will always get the same IP address. (The MAC address will be printed on the serial console)
6. Blast a raw Z80 binary to the ESP32's port 8080.

Writing Z80 code

1. Install binutils-z80 or similar.
2. Edit test.s as you wish.
3. Open a terminal, cd into this project's directory, cd z80-code/
4. make send

Notes

The virtual Z80's IO space is mapped as 1 byte per color channel per LED. ie: IO port 0 is the first LED's first color channel, IO port 2 is the first LED's third color channel, IO port 3 is the second LED's first color channel, etc.
