Overview
The EK-RA4W1 evaluation kit enables users to effortlessly evaluate the features of the RA4W1 MCU Group and develop embedded systems applications using Renesas' Flexible Software Package (FSP) and various IDEs.
Getting Started
Running the Quick Start Example Project
- Power up the EK-RA4W1 board through the USB debug port (J11) using the micro USB device cable connected to a 5V power source. The green power LED will light up.
- The quick start example project will begin to execute blinking the red user LED.
- Refer to the EK-RA4W1 – Quick Start Guide (ZIP) to explore additional functionality of the quick start example project.
Developing Embedded Applications
- Modifying the quick start example project – refer to the EK-RA4W1 Quick Start Guide for instructions on importing, modifying and building the quick start example project.
- Start with one of the many other example projects – choose from many example projects to learn about different peripherals of the RA4W1 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-RA4W1 board with your choice of ecosystem add-ons.
