Unfortunately I cannot read the .sch files, as it looks like they are some binary format instead of the text format that gEDA expects. Would it be possible for you to post the schematics as simple pictures? In my design (see http://www.milovana.com/forum/viewtopic.php?t=3327 for details and schematics) I was able to avoid an extra PCB by using a longer plastic tube to transmit the pressure to the pressure sensor on the main PCB. (Btw, I have experience of open source software licensing, and you have done it absolutely right.) This is quite interesting to find, as I have done something similar myself.

I embedded the EEPROM messages in the .asm file using DE statements org'd to 0xF00000 and incremented for each item. I don't have a USB to serial adapter board so have attached a MAX232, just need some time to hook it up to the PC now. Thinking about wedging the code into the M'chip CDC USB framework and eliminating the RS-232, looks complicated though. I'm considering Internet enabling it as well, perhaps an MSN plugin... Again, thanks for posting the code, it's generated quite a bit of interest here and hopefully there's plenty of fun to be had.

I just opened the EEPROM view and entered them there. That's something I have to look into then. It also appears that I forgot to include the hex file with them in (I have now posted that above. if you import that into MPLAB then go to the EEPROM view you will be able to see the function names) Thanks for showing an interest, hope you have fun with it.

They don't appear to be in the .ASM file.... I might be missing something, but i can’t find any mesages in EEPROM? They don’t appear to be in the .ASM file….
