 # ArduinoProcessScheduler
 A cooperative Arduino object oriented, cooperative process scheduler to replace them all.
 
+This fork is adds a wrapper for STM32 (Arduino_STM32) to implement the same basic Process interface, on top of object-oriented [FreeRTOS TaskCpp](https://github.com/GitMoDu/FreeRTOScpp).
+
+Depends on https://github.com/GitMoDu/FreeRTOScpp .

 ## What is this?
 As your Arduino projects get more complicated, you will begin to see the need for multitasking, or at least appear to multitask. Perhaps you want to check if a button was pressed as often as you can, but you only want to update a display once every second. Trying to do this on your own can quickly turn into overwhelming spagetti code involving `millis()`. `ArduinoProcessScheduler` seeks to simplify this. Simply create your custom Process that needs to be serviced at certain times, and let the scheduler handle the rest.

+/*
+* Example 03: Ex_03_SubProcesses.ino
+* By: GitModu
+*
+* This example expands the Ex_02_MultiBlink.ino example, and demonstrates sub-instancing of Processes inside a class.
+* This allows class definition with a custom Process without needing extra static declarations, sharing the same scheduler.
+* BlinkProcess has 3 BlinkProcess objects that will blink at a diff. period and add them to the scheduler:
+* - blink250 (pin 13)
+* - blink500 (pin 12)
+* - blink1000 (pin 11)
+* Connect an LED to each of these pins and watch them blink.
+* Also added a simple LogProcess to demonstrate the usage of the same scheduler.
