Can you blank the tubes in software? If so you could implement dimming in software, which is all PWM is. No need for a dedicated pin. I did this for an Arduino controlled clock kit I bought. There were no timers left, so I just kept track of whether the tubes should be on or off in the 'PWM' cycle in a small PWM class. Essentially your 'clock cycle' is however fast you can get around your main loop.
I implemented cross fading the same way! -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
