OBEX for 8 Segment LED

NWCCTV

I have one of these 8 Segment LED boards http://www.ebay.com/itm/5V-MAX7219-8-Digit-Red-LED-Display-Module-7-Segment-Digital-Tube-For-Arduino-MCU-/281251260576?pt=LH_DefaultDomain_2&hash=item417be1a8a0

except mine uses 2 Ea. 74HC595D drivers. Does anyone know of a Spin Object for this display?

That link is for am 8-digit 7-Segment display which appears to be made of 2 4-digit modules.

NWCCTV

Yes, I understand this. I only provided that to show the type of display I was asking about.

Post a photo of your display, especially any text on the PCB.

It's silly (IMO) to expect objects for every off-the-shelf design one finds on eBay. If your display uses the 74x595, look for an object for that -- like this:

If it's a 2 digit 7 segment + decimal point display then most likely each output from the '595 is connected to one segment or the dp through a current limiting resistor. If that is the case you can use a look up table to convert the BCD or ascii digits to the segment/dp bits and shift them out using a standard '595 driver.

@Johnny Mac, Thanks for that. I will give it a try later. I did a search in the OBEX for the 74HC595D
and several Items came up but that one did not. So far I have found one of them that may be promising.
