Author: M2OS

• Minimal POSIX-like interface.
• Improved support for Non-preemptive regions (supported in Arduino Uno and STM32f4 architectures).
• Support for CPU time clocks.
• USART console for STM32f4.

Added support for “cooperative scheduling” (Yield_To_Higher operation)

Implemented a simpler ready/suspended queue.

Support for new Arduino devices:

• IR thermometer MLX90614.
• Alphanumeric Display HT16K33.
• EVShield (Shield for EV3 Lego sensors/actuators).

Improvements in Arduino library and added new devices:

• Grove 16×2 LCD Series.
• Elechouse Voice Recognition V3.
• KS0457 keyestudio CCS811 Carbon Dioxide Air Quality Sensor.
• Grove Ultrasonic Ranger.
• Grove Infrared Temperature Sensor.

Improvements in Aduino library

Added new functionalities to the version of M2OS for manycores (M2OS-mc) for the architecture Epiphany:
– Sampling ports.
– Clock synchronization.

Epiphany architecture updated with new scripts and documentation.

The first public version of M2OS is available to download.

The architectures supported in this first version are Arduino Uno, STM32F4 and Epiphany.
