looking for example code to test 6x TPIC6C596C

Using Arduino Project Guidance
1

i bought some display drivers from Sparksfun.
i have them assembled to my displays, but i have looked all over and i am unable to find any test code of any sort.
i plan to use my UNO for the testing.

i found this code, but it is for only testing 2 digits.
https://learn.sparkfun.com/tutorials/large-digit-driver-hookup-guide#example-two-large-digits
but it does not explain all the connections to the UNO.

i'd like to be able to test 6 digit display. some sort of test mode / count

thanks for any help.

What kind of display drivers ? Okay Found it.
They say that several of these boards can be daisy chained. So you do all six displays like that.

  number %= 100; //Reset x after 99

Change that 100 to 10000 (and change 99 in the comment to 9999)

  for (byte x = 0 ; x < 2 ; x++)

Change that 2 to a 4.

There, your example now does 4 digits.

thanks, that worked.. i actually did changes to operate 6 digits. took a while to count up that high, then i discovered that if i changed it to operate 3 digits, then the 4-6 would be duplicated as to what 1-3 was doing.
kinda neat..

now i just have to go the next step and find some code that i can use to turn this display into a GPS clock,

Not really.
Digits 4-6 aren't updated until you push the 'next' 3 digits to digits 1-3.
The shift registers are like single-file train carriages with a door at one end.
If you push passengers in, they will bump each other along - one place at a time, until the very first passenger eventually falls out the other end... and so on!

You could always use a larger increment, like 1111:
0
1111
2222
...
8888
9999
11110
12221
13332

  number += 1111;
  number %= 1000000UL;  //Reset x after 999999
