HI William, I am a realative newbie to programming so I think what I did would
be easyer to understand. I have already done what your are asking for I have a
arduino connected to 3x 595's for 24 Output pins also I wrote a code for it so
it changes based on a RTC. It was for a art project where
Hi all-
I've been circling back to the nixie clock project I am working on that
starts with a base kit of 6 IN-14s each with their own module that contains
a PCB with a 74141 on it. I have never used shift registers before, but
finally got around to some initial experiments driving one 74HC595
I will need three 74HC595s if I go this route (6xABCD, 8 registers per 595
IC). The techniques I had come across on the Arduino consisted of serially
feed bits to the 595 until all 8 registers per chip were full. It would seem
like I need to send 24 bits each second as the clock ticks.

Yep, if you're trying to bit-bang the SPI then you are definitely
re-inventing the wheel. Look at Arduino sketches for other SPI devices
and see how they do it there. I don't have any arduino experience so I
can't be of much help either, but I've used the SPI port on the AVR many
many many times
