In the RE family, Arm®CMSIS-compliant API driver software and Renesas driver software are provided. By using the driver software, each peripheral function can be controlled easily.
Features
- The following software can be used for a software development for RE family.
- CMSIS Driver Package: Arm® compliant API device driver software and Renesas driver software
- Device Driver SW sample code: For users who want to make their source code readability better and complete their application firmware development in a shorter time.
- Low Level code (LLC): For users who are familiar with MCU peripheral hardware modules and want to make direct accesses to the hardware registers to optimize the hardware control, make software execution speed faster, reduce code size.
Release Information
Software can be downloaded from the list below.
Getting Started Guide
The Getting Started is a document that contains the following essential information for development. We recommend that you refer to it when starting development.
- Procedure/method of using driver (initial clock, pin setting, interrupt setting, program allocation method into RAM, etc.)
- How to set up the debugger in the development environment
- trouble shooting
