Exploring RTOS with Galaxia on Energia MT

The availability of the MSP432 LaunchPad and Energia MT gave me the perfect opportunity to discover RTOS.

The new LaunchPad MSP432 brings two major innovations. 
  • On the hardware side, the MSP432 by Texas Instruments innovates with an ultra-low power Cortex-M4F. 
  • On the software side, Energia, based on the Wiring / Arduino framework, becomes Energia MT, or Energia Multi-Tasking. It relies now on TI-RTOS, or Texas Instruments Real Time Operating System.

I'm exploring the RTOS and developing libraries for Energia MT. The RTOS elements are encapsulated into classes with a consistent and minimal set of functions. Of course, all those libraries are developed with embedXcode, embedded computing on Xcode.

The goal is to provide libraries with the same ease of use as the Serial, Wire, SPI classes (among others) provided by the Wiring / Arduino framework. 

All the libraries are bundled in one single package called Galaxia. With LaunchPad, BoosterPack, Energia, let's stay in space and explore new galaxies!

As at today, the libraries exist for the following RTOS elements:

Threads
  • SWI
  • Task
Synchronisation
  • Event
  • Semaphore
  • Mailbox
  • Timer
  • Clock
Warning

Please note this is a work in progress. Some libraries may be available only as pull requests are awaiting validation at the Energia GitHub repository. Other
libraries may be unstable and not fully tested, especially under critical conditions. Lastly, some RTOS elements may have been removed from the last distributions of Energia MT.

​A series of tutorials were also posted on Hackster.io.
