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 with an Arduino connected to one set of 74141 inputs (ABCD) to keep things simple. I was able to get the different digits lit up based on my code, but am wondering if I am missing something in terms of ease of use here.
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. The fact that I have to do this serially one bit at a time seems like a pain in the neck. Am I missing something (I'm sure I probably am) in terms of being able to set all 24 in parallel? I'm hoping someone with more experience using arduinos and shift registers could provide some insights / tips. I'm also open to hearing about how to use these from a uC agnostic perspective if noone on list is doing this with arduinos, but some code snippets would be ideal from the arduino perspective.
