Overview

The RL78/G23-64p Fast Prototyping Board, featuring the RL78/G23 microcontroller, is ideal for various prototype developments. It supports audio playback, LoRa and LoRaWAN-based wireless communication, and more, by sample code. The built-in emulator circuit is equivalent to the E2 emulator Lite and allows programming and debugging without extra tools. Additionally, the board has Arduino Uno and Grove interfaces, access to all microcontroller pins, and high scalability. Renesas also provides an Arduino library that supports creating various programs (sketches) on the Arduino IDE.

Videos & Training

This video demonstrates how to debug sketches using the RL78 Arduino library on a Windows PC within the Arduino IDE. Through debugging, developers can collect detailed information from their sketches and observe the internal behavior of the library. The tutorial uses the RL78/G23‑64p Fast Prototyping Board to illustrate the process step by step.

This video demonstrates how to import sketches using the RL78 Arduino library into e² studio, as well as how to build and debug them. By debugging in e² studio, you can obtain detailed information and verify the internal workings of the library, which is not possible with the Arduino IDE.
