Compile and Upload Arduino Sketch with PlatformIO in Arch Linux running on PC, Raspberry Pi 2 and 3

Posted by:

Preamble

PlatformIO is a python tool to build and upload sketches for multiple Hardware Platforms, at the moment of writing these are Arduino/AVR based boards. This is the only tool working with Raspberry Pi running Arch Linux so far, and I have been searching for some tool like this for a long time.

NB: The over-bearing minion is there because every time my little one sees it, she giggles.

Arduino Interrupts and some of its Usage

Background and rational

In the process of developing a device, we come across a situation that we needed a responsive way to abort the device; However Arduino will be stuck in the middle of loop and only response after that, esp when the only communication to Arduino is via a serial port. We have adapted a very wasteful way of putting the whole ...

Arduino Installation on Raspberry PI 2B Running Arch Linux

Posted by:

Official Arduino IDE does not agree with PI and it sucks any way.

[update] Platformio is a better way!

There are two major ways to compile and upload sketch files to Arduino: a. use IDEs (Arduino IDE, Emacs IDE, Fritzing or ArduIDE). or b. use a terminal. Arch official site explains well, however, most of it does not apply to RasPi with Arch Linux. It DOES work with regular ...
