You are fundamentally correct in all your assumptions about the TT3. You can't load a .t3f file into either a blank PIC, or a existing PIC 16F628 chip, since neither of these have the Byonics bootloader required to install the file. You can update your old TT3+ by purchasing a new, 16F1827 PIC from Byonics, and you will be able to install any .t3f file ( WXtrak, TinyPack, etc) to convert your old TT3 into any compatible device. Not all .t3f files will actually work in a TT3, since some are hardware specific, including all of the Micro-Trak transmitter/transceiver products.?
Byonics recommends TeraTerm because it's free and runs on Windows, but you can use pretty much any any terminal program to load new firmware into a TT3 chip. It's easier for us to help you with any required troubleshooting if you are using Windows and TT, since we use it every day. Again, you won't be able to re-write your old 628 or brand new (blank) 1827 chip without the bootloader, which is closely held.

This query is more to a matter of interest, at least at the moment, but I am confused. I have a TT3+ which uses a 16F628 PIC included in the kit. I note from the Byonics site, they have made other Firmware available for different applications (rather than the basic tracker) and a set of tracker Firmware to revert to the tracker mode (a later version) if you change your mind.? Out of interest, I downloaded the file which includes in the instructions a cryptic (to me at least) comment: "Note only TinyTrak3Plus's with the 16F1827 chip can be upgraded this way." I assume from this, the current TT3+ are shipped with a 16F1827, which it seems is compatible with the 16F628 (I am happy to be correct on this).? There is also a reference to?Tera Term Pro and, reading the instructions, it seems the supplied 16F1827 has some extra code included to allow it to work with Tera Term Pro,? Again, I am happy to be corrected on this.? Now my question: Can I use another method (in particular a normal programmer) to simply load the? *.t3f? file into either a? 16F1827 or even a 16F628 (a new one) and use the programmed device in my? TT3+. I am assuming Tera Term Pro is a Windows programme and, while I can access a Windows machine, I prefer to use Linux.? At the moment this is just a question asked out of interest rather than something I plan/need to do. 73 Brian G8OSN |
