Getting Started
Running the Quick Start Example Project
- The EK-RA6M4 comes pre-programmed with a quick start example project (source code provided in the EK-RA6M4 Example Project Bundle (ZIP)).
- Power up the EK-RA6M4 board through the debug USB 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-RA6M4 – Quick Start Guide (PDF | English, 日本語) to explore additional functionality of the quick start example project.
Developing Embedded Applications
- Modifying the quick start example project – refer to the EK-RA6M4 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 provided in the EK-RA6M4 Example Project Bundle to learn about different peripherals of the RA6M4 MCU Group. These example projects can serve as excellent starting points for you to develop your custom applications.
Building a Custom Hardware
- Start by building a functional prototype – utilize the EK-RA6M4 board with your choice of hundreds of popular ecosystem add-ons.
- Build custom hardware – develop custom hardware by referring to the design and manufacturing information provided in the EK-RA6M4 v1 - Design Package (ZIP | English, 日本語).
