Adjust code

Now that your setup is done, you have to make some changes to the code.
See Installation on how to compile and upload code using Arduino.

  1. Open Arduino and go to A_config.h (second tab)

  2. Change all the #define settings according to your setup. The default settings are for the I2C example setup, just without the Neopixel LED. Be sure not to confuse the GPIO pins with the NodeMCU pins (D0,D1…)! You can find the NodeMCU pinout above.

  3. Don’t forget to change #define USE_DIPLAY false to #define USE_DIPLAY true

  4. Upload your code and test it

  5. Save a copy of the A_config.h file so it’s easy for you to update the software later.
