Yeah, I got quite excited when I first saw the gumstix. I like the modular design, but it starts to get expansive when you factor in all the parts you need. Beagle gives you the performance to run a Linux or Windows desktop, with on-board video for $150. Just add screen, USB hub, mouse & keyboar...

If you haven't already heard of the BeagleBoard, then it's a 3" x 3" PC that runs Linux or Windows Embedded. Costs $149, and for that you get laptop performace, on board video and sound. Just add flash, and your peripherals. Beaglesride.org is focusing on the in-vehicle side of it, staring...

mono/C# would be my preferred choice.

Fred, would a command line tool that reads the serial data be handy? I wouldn't mind putting one of those together, comple with source code based on the latest protocol spec. It would display what it read from the serial port, and also send preset commands.

I wonder if we should specify an end of String character. Byte Zero maybe? Otherwise, how do you send multiple variably sized strings in the same payload. Why would there be any strings other than what is defined? Error conditions? Can't think of more. Neither can I really. Debug information in tex...

Here are my thoughts. [*]CRC semantics, header included, separate, or header not checked, pre escaping, post escaping, 8 bits/16 (I vote 8) 8-bit vote for me. If comms is unreliable, it will probably be obvious, and therefore 8-bit is good enough. My gut feeling is that CRC should be pre-escaping, a...

Fine by me Fred. Don't worry, your not stepping on my toes. Been busy developing stuff for my day job.

I wonder what Stu has to say next :-) HA HA :D Just use a string and have done with it. Let the coders decide how they want to version it. Simply recommend in the protocol spec, that it should be sortable alphanumerically, starting with the name as a constant. FreeEMS Vanilla 1.0.2a FreeEMS Vanilla...

I like the sound of that. This solves another problem i was thinking of the other day, but alas I cant remember it now.
