Thu, 26 Aug 2010 15:18:47 +0000 hourly 1 http://wordpress.org/?v=3.0.1 By: Robert http://www.semifluid.com/?p=43&cpage=1#comment-5635 Robert Thu, 26 Aug 2010 15:18:47 +0000 http://www.semifluid.com/?p=43#comment-5635 @mark It will sort of... The hyperformance uses "EARTHA" as the string instead of "ASTRAL". Also and this is where it gets complicated, the hyperformance uses binary data instead of a $GPRMC sentence. So what does all this mean to you? Well the code has to be rewritten to handle the binary data but the circuit is exactly the same. I know it was nearly a year ago you asked this question. But I thought I would provide the answer in case anyone stumbled along here. If anyone has questions about the hyperformance, you can e-mail me at hyperformance(AT)learn2think.org. Of course replace (AT) with the appropriate symbol and hopefully that won't garner to much spam. @mark

Thanks for the source code. 1. I will only store the value if the diff between values can't be stored in a byte. This will allow me to write over 5 days of infomation to the EEPROM. 2. I will code the PIC to send "ASTRAL" to the tripmate rather than modifying the trip mate. (I'm really really curious why you didn't do this, My other thought was to use a single throw double pole switch hooked inline on the serial cable to get the thing started, so modification wouldn't be necessary and I could use it with other serial devices.) 3. I am going to try to power the tripmate and the pic off the same battery source. 4. I may use a secondary PIC and board to run an LCD screen. Abitious, maybe, but I've got lots and lots of time to figure things out. If you or anyone else reading this wants to track my progress, I will be posing it online hopefully soon. I do have some questions, however, I am well aware that tons of people ask you questions feeling you are obligated in some way to answer them. Please only respond to my questions if you are so incline. Questions: 1) I noticed on some of your other projects you mention that you use the CRC compiler. I am quite poor and can't aford anything but the feebies on MicroChip's website or wherever else I happen to look. Am I going to have a problem compiling your code with one of these? Is there a way I can rectify any problems? 2) Is there any other problems you want to warn me of? Thanks, if you are interested I'll keep you posted. If not... Well when I have a site set up with the project I'll post it here then and anyone who's intrested can have a look. Awesome project thanks for helping on a jumpstart by posting what you did.

It will display the datum as well as log it. It also parses the GPGGA sentence for the altitude information.

It's probably a well known fact, but the software that came with the thing had a fatal y2k bug. A few years ago found a Qbasic routine that at least gets me back the ability to retrieve coordinates from the (expletive deleted) thing. Will the stuff posted here allow me (should I actually somehow do the project) to lose the laptop, or simply to interface to it in a less (?) proprietary way?
