Hi all

··· I need to have "6" 7-segment displays do a little light show. I am using a shift register to control the display, and I got it to display numbers here is the code that I am using:


nonZ = 0························· 'work from left to right······················

for index = 1 to 0

value = mile1 dig index

temp = value

read seven_seg_data + value, value

if temp = 0 then skipmile2

nonZ = 1

skipmile2:

if nonZ=1 OR temp <> 0 then SENDmile2

value = $00

sendmile2:

shiftout displaydata,odoclk,msbfirst,[noparse][[/noparse]value\7]

next



nonZ = 0

for index = 3 to 0

value = mile dig index

temp = value

read seven_seg_data + value, value

if mile1 <> 0 then send

if temp = 0 then skipmile1

nonZ = 1

skipmile1:

if nonZ=1 OR temp <> 0 OR index = 0 then SENDmile1

value = $00

sendmile1:

shiftout displaydata,odoclk,msbfirst,[noparse][[/noparse]value\7]

next

pulsout strobe,1



Thanks,

TC

    Subject: [noparse][[/noparse]basicstamps] 4 Digit Led displays

    Fellow Stampers:

    I am an active stamper and have turned to this group many times and read
    with interest all posts. Every once in a while someone uncovers some great
    deal or product and lets the group know about it. Well I have stumbled
    into a great deal and wanted to let my fellow stampers know about it. I
    was able to purchase hundreds of 4 digit common anode displays
    4" 2.5" and 1.8" and are unloading them on E-Bay. Please do not
    interpret this as a strictly sales pitch but as an opportunity to get some
    really neat LED Displays at a very reasonable price.

    If interested please check the following links to EBAY

    Thanks
    Eric
