goedlink—cross-platform EverDrive N8 Pro serial control software

Note: this tool is in a very early dev state! Core functionality is working, but this has not been widely tested yet.

The EverDrive N8 Pro comes with a USB port for software development and system updates over serial, but the client provided by krikzz doesn't play nice with Linux. This tool aims to re-implement the functionality in golang so as to be easily ported to a wide variety of operating systems.

Build

To manually build, ensure you're running a compatible version of golang and run:

go mod tidy
go build -o goedlink-linux-amd64

On macOS, this likely requires CGO_ENABLED=1:

go mod tidy
CGO_ENABLED=1 go build -o goedlink-linux-amd64
