the problem is that i really do not understand the process of how to do it. I would need some sort of program as well. I have the bin file that would need to be loaded on it. It is just not in my knowledge base
Not sure what your Computer Science / Electrical Engineering background is. If this is too basic of an explanation - charge it to my head and not my heart.
---------
Skimming through the project - it looks like you are attempting the Option 2) Modify an USB-to-serial cable.
You're doing this because:
1) the PCLogBook requires that the dive computer be connected with a USB device (either the $$$ one sold commericially or the inexpensive one you are building.)
AND
2) you must change the characteristics of this custom built USB device by altering the VID (Vendor-ID) / PID (Product-ID) to prevent the OS from detecting it as a standard USB to Serial device. You don't have to understand what this means. Just that it is so.
The 24C02 is an EEPROM that when properly programmed and installed on your custom built USB device will make sure that the VID / PID are altered as required above.
In order to program it - you'll need to purchase / build a piece of hardware to temporarily mount the EEPROM in. This will create the electrical conditions that permit the EEPROM chip to be programmed (burned) with the EEPROM data that you have downloaded from http://www.divecable.com/site/downlo...2303-24c02.zip
You'll also need some sort of software to drive the burner hardware above - something to tell the 24C02, "Hey - this is the data that I want to program you with. Be so programmed!"
You'll find instructions for using PonyProg with SI-Prog on the lancos site - but this project is probably starting to feel like an onion (I've got to build an EEPROM burner before I can build my dive computer interface...) If you want to avoid building the SI-Prog yourself - you could by the EEPROM burning hardware. Googling - I found the following for about $22 (24Cxx, 93Cxx and 25xxx Serial Eeprom programmer E-EPROM) it claims to be compatible with PonyProg - and is compatible with the 24C02 EEPROM. Of course - I'm not vouching for this seller - use them at your own risk.
Once you have either built or bought an EEPROM burner. Use PonyProg - (or another program of your choice) to install the EEPROM data on the the 24C02 chip. Then solder the configured 24C02 chip onto the standard USB to serial device you are modifying.
If you've done everything perfectly - you'll be able to interface your dive computer to the PcLogBook Software.
If you'd like to PM me - I'd be happy to provide more direction
yeah i guess that is what i will have to do. I was hoping to to find someone who had one and just pay them a little to do it for me. thanks for the help. I will order one soon and then see how the program looks to load it. I may need som emore help ;-)
If I had the setup - I'd burn it for you. (maybe someone else will still volunteer...) But my last project of this sort was 20 years ago (a EISA mounted AD/DA converter that briefly lived in my PC until I fried it.) Nowadays - I'm lucky just to find time to dive - much less have other hobbies.
It looks like a fun (if a bit complicated) project. But you'll have learned lots by the end of it! Good luck.
screw learning! I already had someone make the circuit board for me but i realized a little late that the website has not been updated in a long time. This means that the files required to modify the dive rite program were not there so now i have to go the modded USB route instead of modifying the program.
I know it's a bit late, but I'm rarely on the forum. The "files needed to modify the dive rite program" are still on divecable site, and if something changed in the program itself (new version or something) I can look for my source files form the patches and fix them to work again (I think). And the "lazy" way with patching the program is my favorite one, because of the eeprom programming problem .
well I had a friend build the board for me. I even took apart a USB cable to figure out where to stick the EEPROM and cound not find it. I was bummed and then after a year of looking, a dive shop was unloading the clamp/download cable as the computers are no longer made. I was able to get the 200 MSRP cable to 50 bucks. Figured I had just about spent that much already. Sorry i whimped out
