Iam using Freescale's COLDFIRE processor MCF 5485. I have downloaded TCP/IP and USB stack which is freely available.(for coldfire processor). I plan to go for ThreadX RTOS. ThreadX has TCP/IP stack and USB stack which is NOT FREE. Are these stacks RTOS dependent ? so that i can buy only the core OR should i buy these stacks that come with ThreadX. Thanks, VIVEK

Hello group, I'm planning to learn micro-controller programming and will appreciate it if you somebody could help me to decide on a platform to start. I have chose ARM series but currently there are two different models as: 1) LM3S811 2) MCB2300 1) which one would be a better choice for a newbie? 2) which one is better for RTOS? 3) which one has better documentation and sample...

Greetings all, As some of you know, I have been programming embedded thingies for quite some time now. Unfortunately, to date, I have never had a need for, or used, an RTOS. Now I am working on some heavy duty stuff, with TI's DM642 DSP in the middle of each (modular) hardware component. Well, it seems that TI's philosophy for documentation is to spread the specific information that one...

Hi, i'm wondering if there is an (rt)os for uC (i.e. HCS12, C16x,...) that executes tasks, that can be loaded at runtime. In my mind, there is the idea, that there is a central uC with "a lot of binary code" that can be swaped in a (can-, serial-) network between some uC. I don't want to start with an something like uCLinux, because of a limited students budgets... Please name some rtos...

BTW, we use C, currently we don't use an RTOS, but going forward, this is something that we wil...
