Arduino Kernel Release 1.1

Arduino Kernel Release 1.1

Arduino-compatible kernel for the OS. This version includes features of Release 1.1.0. The Arduino kernel will receive only the releases.

Release 1.1.0

ESP-OS Release 1.1.0

The version includes Task scheduler and other improvements.

New features

• Simple task scheduler

Task scheduler

Task scheduler allows you to create and schedule tasks, with different priorities, for example, blinking an led(built-in). Task scheduler also allows you to kill tasks by pid.

Priority map:

• 0 - Highest priority, used for critical tasks
• 1 - Very high priority, used for important tasks, for example in calculations
• 2 - High priority, used for normal tasks that require frequent use
• 3-4 - Higher than normal priority, use for less frequent tasks
• 5 - Normal priority, used for normal tasks
• 6-10 - Lower priority, used for example blinking a led

Commands

• scheduler.create_task(function, period, name, priority)
• scheduler.kill_task(pid)
• scheduler.get_tasks()
• scheduler.get_pid(name)
• scheduler.execute_tasks()

Changes

• General improvements
• Added commands
