Overview
Description
The EK-RA4M2 evaluation kit enables users to effortlessly evaluate the features of the RA4M2 MCU Group and develop embedded systems applications using Renesas' Flexible Software Package (FSP) and e2 studio IDE. Utilize rich on-board features along with your choice of popular ecosystem add-ons to bring your big ideas to life.
Getting Started
Running the Quick Start Example Project
- The EK-RA4M2 board comes pre-programmed with a quick start example project (source code provided in the EK-RA4M2 example project bundle).
- Power up the EK-RA4M2 board through the USB debug port (J10) using the micro USB device cable connected to a 5V power source. The white power LED will light up.
- The quick start example project will begin to execute blinking the blue user LED.
- Refer to the EK-RA4M2 Quick Start Guide to explore additional functionality of the quick start example project.
Developing Embedded Applications
- Modifying the quick start example project – refer to the EK-RA4M2 Quick Start Guide for instructions on importing, modifying, and building the quick start example project.
- Start with one of the many other example projects (provided in the EK-RA4M2 example project's bundle) – choose from many example projects to learn about different peripherals of the RA4M2 MCU group. These example projects can serve as excellent starting points for you to develop your custom applications.
Building Custom Hardware
- Start by building a functional prototype - utilize the EK-RA4M2 board with your choice of ecosystem add-ons.
- Build custom hardware – develop custom hardware by referring to the design and manufacturing information provided in the EK-RA4M2 design package.
