This is a bit complicated to understand, so I’ll just quote the relevant bits from the Space Apps Challenge page<\/a>.<\/p>\n

Proof of concept that threads in a Real Time Operating System for the Raspberry Pi can emulate various Arduinos with help of a library that mimics the Arduino API. This will maximize the efficiency of the ArduSat platform by allowing multiple Arduinos to use dynamically asigned sensors.

A bit more detail…<\/p>\n

This project solves the Ardusat hardware level 3 challenge by using a Raspberry Pi running ChibiOS (a Real Time Operating System for embedded systems). Inside ChibiOS threads runs Arduino code with help of a library that mimics the Arduino platform. The RTOS can be configured to map pins and devices betwen the Raspberry Pi and the virtual Arduinos allowing the maximum use of the sensors in Ardustat. The code and configuration running on the Raspberry pi can be uploaded via serial console for remote management.<\/p><\/blockquote>\n

There are instructions for building and loading the bootloader onto an SD card for the Pi and instructions for uploading scripts here<\/a><\/p>\n

Here’s a video in which the developer, Manuel Rabade, describes his project.\u00a0For English subtitles, turn captions on in the video.<\/p>\n
