I had to fine tune how I was doing that to remove the flicker. I think it is caused by a beat between how often you go around the main loop and what you think the state of the tubes should be. You have to keep of an error term to keep track of the state you should be in.
Anyhow it seems to work and I think the hardware I was programming is quite similar. It is an Arduino uno driving a display shield with no way to PWM the state of the tube. It is hard to know without getting my hands on the hardware. However my code is github here if you want to take a look: https://github.com/judge2005/NixeTubesShieldNCS314/blob/master/NixieClockShieldNCS314HW1.1.ino.
