modemless tnc builders (via bcc)
i have been having some fun experimenting some more with my tnc that was in qex last spring. i have added a couple more features...
1. the ability to send temperature reports in the beacon. you can format the temperature weather report as you wish, even in aprs format and it can be seen at your favorite aprs web site. i used the dallas ds18s20 1 wire sensor. very interesting device. it costs about $4 and can be remoted if you want. the temperature sensor is very small (looks like a regular transistor).i am using it to do some remote water temperature readings and it works great. the tnc will provide either degrees c or f, the high and low for the day, and a sequence number. you could, with some code mods use any of the "1 wire" parasitic dallas devices. a checksum is used over the 1 wire bus to insure data integrity. you can look at the ds18s20 specs at
http://www.maxim-ic.com/quick_view2.cfm/qv_pk/2815 2. an option to filter out non printable chars monitored from the terminal. keeps your terminal from doing screwy things when someone is sending control chars, like some of the dx clusters.
3. some diagnostic messages to help debug gps cable and option problems.
also, fixed a couple of other anomolies i found.
anyway, the new source is attached and you are welcome to use it. details of the new features are in the file near the front.
you do not have to add the ds18s20 to use the new software.
let me know of any problems you encounter.
have fun!
