This project is based on the well structured library "gobot", see https://github.com/hybridgroup/gobot. Basically i2c bus devices are used here.
The easiest way to install is to run go get -u github.com/gen2thomas/gobrail.
The hardware structure will be configured with a plan file in json format. See folder docs/breadboard_controller/ for examples.
The hardware of "Type 2" is needed together with digispark, than simply make run.
Please have a look at folder docs/breadboard_controller/ for using with a breadboard.
First run make to create all binaries for target systems. Choose the binary for your target from output folder and copy to your target device.
- gobrail => amd64
- gobrail_raspi => Raspberry Pi
- gobrail_tinker => Asus Tinkerboard
Make the file executable at your target device and start it by e.g. ./gobrail_raspi -help to list command line parameters and its defaults.
For initial tests the "Type 2" board can cleaned from MOSFETS's. Using another adaptor is also possible. Please see the gobot documentation for this topic.
This is prototype software. It is a long way to make it work in real model railroad environment.
- lamp - single output on/off
- two light signal - two outputs green on -> red off and vice versa
- turnout - two outputs switched on, configurable between 0-1 second, to switch between main and branch
- button - read one input
- toggle button - read one input, use rising edge to change the state
- improve timing by using events and/or concurrency
- add configuration interface
- add first locomotive decoder (hopefully possible to gobot devices)
- virtual boards (a button or lamp can be mapped to an virtual IO, which provides an "external service")
