h1. RTOS

page to save some thoughts on firmware directions

current situation for released firmware:

* build online on mbed.org

* using closed mbed libs for e.g. ethernet

next step

* do offline compiling using gcc4mbed ->works now!

* still using mbed libs

When making a step away from the mbed libs, we probably also need to look for an alternative of the MBED e.g. LPC1768. -> not required due to open sourcing mbed libs

feature list for new firmware environment

* open source

* ethernet support

* build environment in linux

* support for cortex-m3

* board support for LPC1768 / LCP1769

* RTOS

* easy to implement in the current code

* ethernet based on lwip (same as current code...)

some alternatives (based on being open source and cortex-m3 support)

for now, this is a start of getting to know the firmware structure:
