esp-idf: breathing led using c++

Rationals

The goal of this experiment was to:

• Port the arduino breath/blink led to the esp-idf framework
• Use esp-idf task
• Objectifying task creation in FreeRTOS

The port

I couldn’t figure out how to get my led to breathe as smoothly as it did with the Arduino framework. To figure it out I:

• Cloned and build the Arduino framework
• Reversed engineer how the Arduino framework led channel is implemented
• Created my own LedChannel class based on the Arduino C implementation
• note the class is a very poor attempt at doing so. I just ported the bare minimum for my app to work.

Objecting task creation in FreeRTOS

I simply followed the instructions from that wonderful post: Objectifying task creation in FreeRTOS – Electrónica y Sistemas Embebidos OBJECTIFYING TASK CREATION IN FREERTOS (II) – Electrónica y Sistemas Embebidos
