embOS for Texas Instruments MSP430 was developed for and with Rowley compiler and supports all memory models offered by this compiler.
It comes with an easy to use start workspace and start project for Rowley's CrossStudio V1.2. Software development with simulator or MSP430 Flash Emulation Tool using Rowley's built-in debugger is supported.
