evilrevolution Posted January 28, 2010 Report Share Posted January 28, 2010 I'm keen on reading the speed signal (wired, not GPS) through a custom app. Im guessings its just a serial port or something, but any advice hould be helpful rather than trial & error Quote Link to post Share on other sites
FourG Posted January 28, 2010 Report Share Posted January 28, 2010 I'm keen on reading the speed signal (wired, not GPS) through a custom app. I'm guessings its just a serial port or something, but any advice hould be helpful rather than trial & error The schematic for the AV board in the F900/90BT repair manual has the speed sensor signal going through a margining network and then over to the Navi board into a Xilinx CPLD used for timing control. The schematic doesn't call out how the CPLD connects to the Titan CPU, it may be a GPIO/interrupt pin or a two-wire interface. Might still be trial-and-error territory.
