Large Digit Drivers

Post by Bill_H » Sun Oct 22, 2017 6:27 pm

I have wired up two of the large digit drivers to bid LED segments
I'm running the 2 digit test program using an Uno and they work fine Except...
The digits are reversed. The tens digit is counting the ones and the ones digit is counting tens

Unfortunately the box is all put together and it is a doable but very unpleasant task to rewire.
I was hoping I could do something in the software to fix it.
I've looked over the TPIC6C596 datasheet but it's a little over my head.

I don't fully understand how it's shifting the data from one digit to the other.

Can someone help me understand this a little better?
These make an awesome display!
