Cortex-M, KEIL

embOS for Cortex M was developed for and with the KEIL MDK-ARM and uVision IDE and supports all memory models offered by this platform.
It comes with easy to use start projects for the KEIL uVision IDE. Initilization code for different Cortex M starter boards is included.
embOS for Cortex M is fully CMSIS compliant.
Software development with the uVision debugger with JTAG tools like J-Link is possible.
