REQ: Info on functionality of LED digital display
I have a Brantz International 2 Pro rally trip meter which can, when seleced
by a toggle switch, give a display of your average speed on an LED digital display. This trip meter is positioned in fron to the navigator in Targa Rallying and I want to duplicate the average speed readout on a panel in front of me, the driver. What is likely to be the signal that creates this digital display, would it be a voltage that is interpreted by the LED readout or some thing else entirely? Any help or guidence on how to do this would be very much appreciated. Mike S |
Info on functionality of LED digital display
It's most likely a binary signal (BCD - binary coded decimal) that is
lighting the segments of the LCD. You may have a voltage to freq. converter running to a counter then to your BCD decoder or the voltage amplitude is being sampled and running to the BCD decoder. Also probably using grey scale coding to prevent the read out from jumping all over the place.... "AHS3903" wrote in message s.com...
