===== Getting Started =====
==== With CLion ====
  * open CLion and create PlatformIO project there. You should have ''setup()'' and ''loop()'' created for you
  * in terminal search for libraries you need. Example: ''pio pkg search irremote''
  * add in ''platformio.ini'' 
<code>
lib_deps =
     <ADD YOUR LIBRARY HERE>
</code>
  * In CLion: ''tools'' -> ''PlatformIO'' -> ''Re-Init''

==== Without CLion ====
  * list boards: ''pio boards esp32''
  * create new directory: ''mkdir path_to_the_new_directory''
  * go to it: ''cd path_to_the_new_directory''
  * initialize board: ''platformio project init --board esp32dev'' 


==== edit platformio.ini ====
<code>
upload_port = /dev/ttyUSB*
upload_speed = 921600
monitor_speed = 115200
build_flags =

; https://docs.espressif.com/projects/esp-idf/en/latest/get-started/get-started-wrover-kit.html#rgb-led

-D LED_BUILTIN=2

</code>


===== Libraries =====

  * install example: platformio lib -g install https:%%//%%github.com/Makuna/NeoPixelBus.git\\

  * then add to platformio.ini NeoPixelBus


===== Useful commands =====

  * pio run - process/build project from the current directory
  * pio run --target upload or pio run -t upload - upload firmware to a target
  * pio run --target clean - clean project (remove compiled files)
  * pio run --help - additional information
  * pio device monitor - serial port


===== unsolved: =====

  *  change serial port
  *  monitor
  * add library


===== ESP32 Core Board V2 / ESP32 DevKitC =====

  * no built-in LED.

  * the "[[https://github.com/Makuna/NeoPixelBus/issues/152|right]]" way to do neopixel (where <X> can be 0 through 7 and PixelPin can be any pin below 32):

''NeoPixelBus<NeoGrbFeature, NeoEsp32Rmt<X>Ws2812xMethod> strip(PixelCount, PixelPin);''
