embOS for RENESAS R32C was developed for and with RENESAS HEW compiler and supports all data memory models offered by this compiler.
embOS for R32C comes with an easy to use start project for an R32C CPU which may be used with the HEW.
Software development and debugging with E8a emulator as well as using the simulator is supported.
