Speaking of navigation, this is interesting, Locosys makes something called Traffic Message Channel (TMC) using the Silicon Labs SI4701 FM tuner RDS feature to gather real-time traffic and weather information. They use an 8051 microcontroller to read the RDS data from SI4701 and convert it into NMEA sentence format, which is of course, also a format used by GPS receivers. So, if you have onboard GPS, and bolt-on FM tuner with RDS, and some processing, you could do something similar. The NMEA part presumably is just to make it somewhat standard, is useful data on its own, but this is quite interesting. http://www.locosystech.com/download/module/TMC-1513_datasheet_v1.1.pdf I'm going to design just a very simple breakout board for the SI4701 to start playing around with it, this RDS stuff is very interesting. Later will make another board with SI4701 and small microcontroller plus audio codec. Microcontroller will read the RDS and also control/configure the FM tuner. Analog audio output would work alone but could also input into Neo or other application. Currently in the middle of switching jobs and residence though, so it may be a short while before I get any boards made. -- Doug _______________________________________________ OpenMoko community mailing list [email protected] http://lists.openmoko.org/mailman/listinfo/community
