Wirelessly receive and compile teensy/arduino code

[pmarct]

So the project consists of two rasberry pis that are connected via wifi through a server-client relationship. One of the pis is connected to a teensy microcontroller and the other pi is strictly used to send commands and new code.

So far I can send and receive data/files between the two pis via Python sockets. However, I need to create a script that receives the new teensy/arduino code file and automatically compiles and uploads it to the teensy via the command line.

I've searched this countless times and haven't found a clear way of doing this, could anyone help or point me in the right direction?

Have you looked at arduino-cli

Agreed, use the commandline tool for Arduino, not the IDE.

Then you can send the source file, build it and upload it to the Teensy. all from a shell script or ox.popen calls from Python .

https://github.com/arduino/arduino-cli

To compile the sketch you run the compile command passing the proper FQBN string:

$ arduino-cli compile --fqbn arduino:samd:mkr1000 MyFirstSketch
Sketch uses 9600 bytes (3%) of program storage space. Maximum is 262144 bytes.

To upload the sketch to your board, run the following command, this time also providing the serial port where the board is connected:

$ arduino-cli upload -p /dev/ttyACM0 --fqbn arduino:samd:mkr1000 MyFirstSketch

Can you use arduino cli for teensy? I am using a 4.0 and I don't even think teensy cli supports the 4.0 yet

I don't know. Have you tried?

It's a Teensy issue so you could try the Teensy forums.
