Hi, i want to import freeRTOS to the LPC1758, using Keil uvision and the Keil MCB 1700 evaluation board.
I’m really new at this and don’t know how to start (which Demo is the best for me?). Has someone used this configuration and can give me a short starting help?

Try here for starters. http://www.freertos.org/porting-a-freertos-demo-to-different-hardware.html As this is a Cortex-M device you could really start with any FreeRTOS Keil Cortex-M project, although starting with an LPC based one would be best. Regards.
