Debugging

  • Step 1: Set up the system

Prepare master module: Microduino-Core+, Microduino-FT232R, Microduino-nRF24, a button and a bread board

Prepare slave module: Microduino-Core, Microduino-NRF24,Microduino Duo-V and an LED

  • Step 2: Set up the button

Button connection: Adopt internal pull up. (You need to define it in program.)

  • Step 3: Download the example program

Download the program:

Choose "Microduino Core +(Atmega644P@16M,5V)" as the board of the master machine and "Microduino Core (Atmega328P@16M,5V)" as that of the slave machine, then download directly.

Result

Just download the program to the core board and you can control the LED on the slave machine through the button on the master machine.

Note

  • The sending and receiving parameters of Microduino-NRF24's communication function should be matched.
  • The button adopts internal pull up, needed to be defined in program.
