Getting Started
Developing Embedded Application
The software development to evaluate RX671 MCU’s function could be started immediately using the e2 studio IDE and the RX software package that includes peripheral function drivers, middleware, and usage documentation.
- Get familiar with EK-RX671 through the Quick Start example project –The Quick Start example project shows:
- Communication between EK-RX671 and Host PC through USB to Serial interface
- Control User LEDs via User Buttons
- Quad-SPI Flash Read/Write Operation via QSPI
- Start with one of the application projects – Choose from application projects to learn about the different peripherals of the RX671 MCU Group. The number of projects will grow progressively over time. These example projects can be downloaded from “Design & Development” and serve as excellent starting points for you to develop your custom applications.
- Audio Output/Input project via Serial Sound Interface (SSIE)
- HMI application project demonstrating SPI LCD display and Cap Touch functions.
Building a Custom Hardware
- Start by building a functional prototype – Utilize the EK-RX671 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-RX671 Design Package.
