I am trying hard to avoid embedded stuff these days, but potential contract has come my way recently that needs some embeeded stuff. So whilst I am nutting out requirements I also need to put thought to software. I have made the descision that the software must be based on an OS and must have a c++ compiler. RTOS is not required. So the debate in my brain has been fired off. My first thoug...
