PlatformIO is an open-source ecosystem for IoT development.
Cross-platform build system, IDE integration and continuous testing. Arduino, Espressif, ARM and mbed compatible.
See our blog post introducing PlatformIO.
PlatformIO IDE is built on Atom open-source ‘hackable text editor for the 21st century’ built by the GitHub. See PlatformIO IDE Install guide for more info.
Note: skip this section if your would prefer to use PaltformIO via it’s excellent command-line interface
These install steps have been tested to work on Linux, Mac and Windows.
If running windows:
Python will also need to be installed, see PlatformIO IDE install-guide *
USB to UART adapter windows drivers will need to be installed
The first time Atom IDE is opened after a few seconds PlatformIO will finish the installation and then display its home page.
Open emonTx3 Firmware
Download emonTx3 Firmware GitHub repo either via git clone or downloading the zip and extracting.
From the PlatformIO Home screen in Atom IDE choose
Open Project (1)*
Navigate to the standard emonTx Firmware
You should see the emonTx34_CM firmware files in the file-tree on the right-hand-side of the editor
Once change has been made save then file then compile with PlatformIO by clicking
If this is the first time the code has been compiled PlatformIO will ask if you want to install all the required libs that are specified in
platformio.ini. See PlatformIO library manager.
If code compiles successfully upload the firmware by clicking on
Note: A USB to UART cable is required to upload to emonTx / emonTH
After successful upload check nodeID has changed by viewing serial output, click
Serial Monitor (4)and choose
PlatformIO Command Line
PlatformIO works great from the commandline, follow these instructions to install and run platformIO from the commandline. See the excellent PlatformIO Quick Start Guide for more info.
1. Install PlatformIO via commandline
The easiest way if running Linux is to use the install script, this installs pio via python pip and installs pip if not present. See PlatformIO installation docs:
$ sudo python -c "$(curl -fsSL https://raw.githubusercontent.com/platformio/platformio/master/scripts/get-platformio.py)"
2. Clone emonTx / emonPi repo
git clone https://github.com/openenergymonitor/emontx3 cd emontx3/firmware/emonTx34/emonTx34_CM
git clone https://github.com/openenergymonitor/emonpi cd emonpi/firmware/emonPi_CM
3. Compile with PlatformIO CLI
$ pio run
4. Upload with PlatformIO CLI
$ pio run -t upload
The first time platformIO is run it will ask to install the required libraries and avr toolchain. The required libraries are defined in platformio.ini in the project folder.
4. View serial port with PlatformIO CLI
$ pio device monitor
