ChRt

ChRt - ChibiOS/RT Arduino Library

This is a version of ChibiOS for Arduino. I am starting a new repository since this version is not backward compatible with the previous libraries. Both AVR and ARM are now in a single library.

Teensy 4.0 has support for free running tick-less mode and periodic mode. The default for Teensy 4.0 is tick-less mode. Edit libraries/ChRt/src/teensy4/chconf_teensy4.h to select periodic mode or change parameters for Teensy 4.

See this article about ChibiOS tick-less mode:

http://www.chibios.org/dokuwiki/doku.php?id=chibios:articles:tickless

AVR also supports tick-less mode. The default is periodic mode. Edit libraries/ChRt/src/avr/chconf_avr.h to select tick-less mode.

Due, SAMD, and Teensy 3.x are supported in periodic mode.

The base code for ChRt was written by Giovanni Di Sirio, the author of ChibiOS/Nil and ChibiOS/RT.

See this site for detailed documentation of ChibiOS/RT.

The kernel is version 6.1.3 of ChibiOS/RT from ChibiOS release 20.3.3.

If you are installing from the GitHub repo zips, rename the folder ChRt before copying it to your Arduino/libraries folder.

Please read libraries/ChRt/doc/ChRt.html for more information. See the Examples section of the html documentation.

Start with the ChBlink example which is traditional for almost every RTOS.
