ModMyPi Programmable Christmas Tree examples in Go

This small program contains examples similar to the examples provided by ModMyPi for interacting with the GPIO-controlled LED Christmas Tree. Tested with a Raspberry Pi Zero 2 W running 32-bit Raspbian Lite. Using the go-rpio library to interface with the GPIO system.

Usage

Build cross-compiled from an x86 PC:

$ make build

Use scp or another tool to move the binary to your Raspberry Pi. Then:

Run a similar pattern to the "ants" example from the original ModMyPi repo.

$ ./mmpxmas-go ants

Turn off all LEDs:

$ ./mmpxmas-go clear

Similar to "alt" example:

$ ./mmpxmas-go alt

Even and odd indicies:

$ ./mmpxmas-go mod2

Light one row at a time:

$ ./mmpxmas-go rows

Flash consistent green or red when BTC price is up or down minute-to-minute.

$ XMAS_COINMARKETCAP_KEY=your_key_here ./mmpxmas-go btc
