Getting Started

Running the Quick Start Example Project

  1. The EK-RA6M5 comes pre-programmed with a Quick Start example project (source code provided in the EK-RA6M5 Example Project Bundle.
  2. Power up the EK-RA6M5 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.
  3. The Quick Start example project will begin to execute blinking the blue user LED.
  4. Refer to the EK-RA6M5 Quick Start Guide to explore additional functionality of the Quick Start example project.

Developing Embedded Applications

  1. Modifying the Quick Start example project – Refer to the EK-RA6M5 Quick Start Guide for instructions on importing, modifying, and building the Quick Start example project
  2. Start with one of the many other example projects – Choose from many example projects provided in the EK-RA6M5 Example Project Bundle to learn about different peripherals of the RA6M5 MCU Group. These example projects can serve as excellent starting points for you to develop your custom applications.

Building a Custom Hardware

  1. Start by building a functional prototype – Utilize the EK-RA6M5 board with your choice of hundreds of popular ecosystem add-ons.
  2. Build custom hardware – Develop custom hardware by referring to the design and manufacturing information provided in the EK-RA6M5 Design Package.
