Nervo

A nervo system for raspberry pies that makes working with multiple microcontrollers less of a pain

Requirements

Go version >= 1.12

Uses go modules -> Should be cloned outside the $GOPATH or explicitly set the env var GO111MODULE=on

Usage

1. Run the server on a raspberry pi
   1. Build the server with make build-for-pi
   2. Put the server binary on the pi
   3. Run the binary!
2. Build the command line binary with go build -o nervo-cli cli/main.go
3. Put the cli binary somewhere inside your $PATH
4. Run nervo-cli <host/ip of your pi >:4000 [path to a local directory where you have .hex files that you want to flash to the microcontrollers]

Project structure

• cli hosts the command line code
• server hosts the entrypoint for the server
• proto holds the .proto files and generated code for grpc communication between the server and the cli
• controller.go is an abstraction for all interactions with the microcontrollers
• manager.go makes sure only one goroutine can access controllers at a time
• explorer.go notifies the manager about the current microcontrollers
• grpc_server.go defines the grpc-endpoints that are translated into func calls on the manager
