How to use a register in Arduino

Register Controller is capable to read or write microcontroller registers, which you can do through the serial port as you can see in the 3rd video, below. Registers are memory blocks containing essential data for controlling or setting up microcontrollers. Learn more about register functionalities from the microcontroller's datasheet.

Prerequisites:

  • Ozeki 10 installed on your computer
  • Programmable board (Arduino Mega/Nano/Uno or any Ozeki Matrix Module)
  • USB cable between the board and your computer

Step 1 - Plug a board into your computer

Choose your board for the Register Controller and please plug it to your computer

Step 2 - Upload code to the microcontroller

(Here is the code to upload)

Step 3 - Start a serial monitor to try the register

Step 4 - Understand the register protocol

You can communicate with the Register Controller through a serial monitor, with the following protocol.
