ZigBee

[Paul Evans]

Hi,

I wanted to correct what I said about the license from Microchip. I went 
back and looked. To use Microchip's code you need to use the Microchip 
RF chip and a Microchip MCU.

There's a glimmer of hope though now that there's Microchip parts 
running MIPS cores instead of the little Harvard architecture devices 
they're known for. With enough memory I believe these devices would be 
port candidates for RTEMS.

Best,

    -Paul
