virtualhomeduino Build Status

quickly hacked together proof of concept stuff for virtualhomeduino

Changed Configuration

Added pigpio library support, configuration uses GPIO pin numbers instead of wiringPI pin numbers. Example configuration:

{
  "plugin": "homeduino",
  "driver": "gpio",
  "driverOptions": {},
  "enableReceiving": true,
  "receiverPin": 17,
  "transmitterPin": 18,
  "active": true,
  "connectionTimeout": 120000,
  "rfrepeats": 20,
  "debug": true
}

Building

Cross compile on a linux box

Prerequisites

  • assuming you compile on Debian/Ubuntu
  • in order to be able to cross compile vhduino on a normal computer running Debian/Ubuntu you need to install git
$ sudo apt-get install git

$ git clone https://github.com/layereight/virtualhomeduino.git
$ cd virtualhomeduino
$ make

Makefile compile steps:

  • clone Raspberry Pi cross compile tool chain (raspberrypi/tools, ~190MB)
  • clone RFControl with commit 70413e8
  • clone pigpio with commit 1aa4cca (V64)
  • cross compile pigpio
  • cross compile virtualhomeduino sources (pigpio_functions.cpp, pigpio_rfcontrol.cpp, virtualhomeduino.cpp)
  • cross compile vhduino binary

Compile on a Raspberry Pi

Prerequisites

  • assuming you compile on Raspbian
  • in order to be able to compile vhduino on a Raspberry Pi with Raspbian you need to install the pigpio package (library and source files) and others
$ sudo apt-get install pigpio build-essential git

$ git clone https://github.com/layereight/virtualhomeduino.git
$ cd virtualhomeduino
$ make -f Makefile.rpi

Makefile.rpi compile steps:

  • clone RFControl with commit 70413e8
  • compile virtualhomeduino sources (pigpio_functions.cpp, pigpio_rfcontrol.cpp, virtualhomeduino.cpp)
  • compile vhduino binary

Runtime requirements

  • the vhduino binary is dynamically linked
  • assuming you want to run vhduino on Raspbian you need to install the pigpio package
$ sudo apt-get install pigpio

Testing

  • build the project as described above
  • assuming you have the pimatic homeduino plugin installed
  • copy the vhduino binary to the plugin's directory on your Raspberry Pi, e.g.:
$ sudo cp vhduino /home/pi/pimatic-app/node_modules/pimatic-homeduino/node_modules/homeduino/bin/vhduino
  • exact procedure would be:
    • stop pimatic
    • backup the old vhduino binary in the homeduino plugin directory
    • copy the new vhduino binary to the homeduino plugin directory
    • start pimatic
    • adapt receiverPin and transmitterPin configuration in homeduino plugin (pin numbering changed from wiringpi to pigpio)
    • restart pimatic

TODO

Contributors

  • WebWire-NL: migrating the whole project to pigpio making it compatible with newer kernels(>=4.9.x)
  • layereight: improving the project's build process
