Firmware
PlatformIO is recommended as the easiest way to compile and upload Arduino compatible firmware for emonTH. One of the big advantages of using PlatformIO is all libraries can be automatically downloaded. Arduino IDE can also be used but libraries must be manually installed.
Compile & Upload Firmware Using PlatformIO
For a full guide and installing and using PlatformIO (including visual IDE) see 'Compiling' User Guide Section. Assuming platformIO is installed
$ git clone https://github.com/openenergymonitor/emonth2
$ cd emonth2
$ pio run
$ pio -t upload
Hardware
emonTH hardware is fully open-source. See hardware folder of this repo for Gerbers, Eagle CAD design, BOM & port map.
