Hi Richard, You mentioned you have a working solution to digit fading? I am pretty much in the position with designing a Nixie clock using the HV5622 chips. I have worked out most of the PCB design and got a few prototypes boards made up. The HV5622 chips are in series and I've managed to make up some code in Arduino IDE and can control individual pins/digits using ShiftOut() which is inherently a bit slow with moving data to the registers. I made up a fade table to quickly transition back and forth between the previous and next digit to give the illusion of cross-fading. This worked well for the most part, until I have more than 1 digit fading, then the latency starts to become more noticeable and the digits star to flicker in transition. After countless hours of reading, SPI seems to be the way to go as it's way faster to shift data out, however I am still in the middle of working out how to use SPI with the HV5622 registers and Arduino as I'm just getting random digits appearing all over the place. I guess the next step after that was working out how to cross fade digits. Would you be so kind with sharing what you came up with? Better than trying to re-invent the wheel :)
Thank you. / Owen On Sunday, 3 May 2020 at 18:06:15 UTC+10 Dekatron42 wrote: > There's another way of dimming/fading described in this thread with source > code on Github - not mine, just remembered it. > > > https://groups.google.com/forum/#!searchin/neonixie-l/fading$20table%7Csort:date/neonixie-l/bh7kymv2xQA/MogsmOnHAgAJ > > /Martin > -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
