vertical speed + and -.

[Jan 737]

Hey freunde,


A little question, I'm plannig a 737ng MCP and this one use for the vetical speed display 5 digits.
The first one for the + or - and the other four for the actual v/s.
Are the +/- provided by FSbus (version 2)?

Regards Jan.

Hi Jan,

- is implemented since first version. A + is not implemented.
The reason: a 7 segment display cannot show a nice +

Maybe do a separate + / - indicator with the LED module. You might be able to get a special alphanumeric segment led and hook up just the "plus" sign with some wires and wire that as a led in fsbus - then if the value is positive have it light up, and if it is negative, have just half of the segments light up, so that it shows just a "minus".

If it is the same size as your 7-segments, you might be able to put it right next to them.

Dunno, that might work.
