C16x, Keil

embOS for Infineon C16x CPUs was developed for and with KEIL compiler and supports all memory models, except TINY.

It comes with an easy to use start project for KEIL uVision2 IDE. Software development with Simulator and ROM-Monitor is supported. Fast interrupts supported since embOS version 3.10p.
