If you understand how a dekatron works, you can apply that knowledge on how to cycle the cathode signals. You'll notice on the datasheet that all cathodes, except one, are grouped together. The one isolated cathode (pin 9) will serve as a reset to get the device into a known state.
To advance one tick, you would pull pin 8 low (while pin 9 is still low), wait perhaps a few hundred usec, then release pin 9. This sequence 'transfers' the ionized cloud to the next cathode. To advance another tick, pull pin 3 low, while keeping pin 8 low, wait, then release pin 8. To move the glowing cathode, you basically sequence the cathodes so that there is always at least 1 cathode energized at all times, and energize an adjacent cathode to 'move' the glow. To get a solid glowing bar, rather than an individual pixel, you would need to cycle the process rapidly. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
