Vfd vaf1613-12lsr2

Good Morning

Have bought a VFD on ebay - 16 character starburst (removed from a fruit machine)

Ive not had any luck with it so far....

Has anyone had any experience with these displays and know how to get them working?
Ive got a 12v supply to the unit, and have been trying to send data...nothing so far...

SYMBOL resetvfd = PORTC.0 'Reset
SYMBOL clockvfd = PORTC.1 'Clock
SYMBOL datavfd = PORTC.2 'Data

PAUSE 2000
'-------------------------------------------------------------------------------
resetvfd = 1

PAUSE 1000
resetvfd = 0
PAUSEUS 50
resetvfd = 1
PAUSEUS 150

SHIFTOUT datavfd,clockvfd,5,[$FF,$C0,$A0,$04,$04]

Just spit balling,
Did you make portc.0 digital? I'm thinking you might need that logic level.
You might try swapping resetvfd=x values and/or adding a longer delay. Seems it's only out of reset for 50us which may be too short of a time to see display.
Again may be of no use but it's the first thing I thought of.

Thanks for the reply

I've tried playing around with the delay times, different shiftout modes today
still nothing

the pic i'm using is 16F877 @ 20MHz
PORT C all set to O/P - I Believe all of port C is digital I/O

Not sure if this helps, the digits of the model number after the dash are different, but this might work.....
