I think the 4109 is the best way to go for this project. Regarding clock speed, th HV5122 accepts data at up to 8MHz. The uC runs at 16MHz. I'm not sure how many clock cycles it take to send each bit, but I doubt that it could reach 1MHz so the 4109 should be good even clocking at full uC speed. The refresh display refresh rate will be 100 milliseconds, but that will increase when fades and effects are added, probably to around 10-20 milliseconds.
I'll update the schematic shortly. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
