Not really GPS, but the similarity between the comand formatting is striking.
So it's basically just "switch {case}"-es?... Was thinking of something more fancy
Thanks for the hint! That's definitely useful!
If it happens that this project comes to fruition, or at least close to it, I'll post...
Re: PIC terminal
Thank you!
That looks like one of the most complete tutorials on RS232 I've seen so far...
Some type of C, of course. Probably Mikroelektronika's MikroC
Don't have a problem anymore... it just went away... somehow...
The jumpers don't look bad... But might be... I doubt I'll actually ever know the REAL cause...
I should also probably trim the crystal's terminals... It's not only placed in a socket (another probable source of trouble), but...
Yep... They're (jumpers and all) ok...
I haven't touched the code since yesteday when it DIDN'T work as expected (severe mangling of strings), and the jumpers for weeks.
Yesterday when I left I put the board back in its box and this morning I took it out and put it on my desk. I can only...
Problem is I don't have a replacement...
About the driving/oscillator problem mentioned above
It looks like a HC-49 type package, 10MHz, parallel mounted with 2 22pF caps. It replaced a similarly packaged but a lot more battered, presumably 8MHz crystal (the writing on the case wasn't that...
Thanks for the quick reply!!!
I agree. I found it hard to believe that my brand new, shiny 10meg xtal would fail after a couple of days.
However, the entire system (xtal+board+uC) worked fine between the changing of the old busted crystal and a couple of days ago. Why?
If, indeed, there were...
PIC terminal
Hello again
I'm thinking of making a PIC terminal.
It'd take commands from a PC via serial, display them on serial, process data(ex: from sensors) and then perhaps send them back to the PC.
What's new to me is the command interpreter part of the software.
Commands would be...
Hello! I have a weird-ish question here
What causes metal encased quartz crystals to fail?
My problem is this:
I'm working on a microcontroller devboard. It's not mine, someone lent it to me. When I got it, it was kinda' old and dusty, like it stood for maybe a year or 6 months on a shelf or...
