Hello

I have modified the shifter mechanism in a custom vehicle so that I can't
use the stock shift position display.

Would it be posible/practical to use a single character 16 segment or led
matrix unit to display the characters 1,2,3,D,N,R,P from a signal given by
a magnet activated reed switch for each position as the switch is closed
by a magnet attached to the shift lever? What driver/controller might I use?

Any comments and opinions will be appreciated.

Thanks for pointing me to the Picaxe microcontroller. It's a fascinating device
and I think it will do what I want. In fact, I think I can drive a single character
16 segment led display directly from the chip.

I checked my Helm manual for the vehicle involved (2006 grand prix, engine
and dash and wiring swapped to a '88 fiero) and found that the transmission
provides the pcm with the shift position by means of 4 coded lines. By configuring
the Picaxe 28X to have 4 i/p's and 16 o/p's, I can get the shift position by
splicing from these coded lines to the Picaxe i/p's and then program the o/p's to
activate the segments for each character I want to display.

What do you think?
