Re: [neonixie-l] Nixie Clock - Direct Drive HV5530

Beautiful, works like a dream! 

I’ll go on and play around with GPS and Motion sensor features.

If you don’t mind, I’ll ping you again for anything quick but I’ll try to 
understand the code myself first.

You did save me a couple of nights going through the code though :)

Thanks so much.

Max

[SWISSNIXIE - Jonathan F.]

Hi

If I understand correctly, you need to alter the code in the section 
"menuItemHandler"
https://github.com/sgtJohnny/sunix/blob/master/sunix.ino 

The function calls on line 639 and 654 do set the values to the three tube 
groups, if you do not have the seconds column, you would have to change 
this this:
*formatOutput(menu_item, 255, currentVal, 0, 0);  *and set the currentVal 
to the second tube group resulting in *formatOutput(menu_item, currentVal, 
255,  0, 0); *

Re: [neonixie-l] Nixie Clock - Direct Drive HV5530

[Max Di Noi]

Hi Jonathan,

I have built this clock and works well. I have however decided to go for a 4 
digits version instead of 6. I can manually set the time, no issues. But when I 
go through the parameters menu, I can see the menu number but not the parameter 
numbers of each menu as the code is displaying those using the second digits 
which I don’t have.

I can code in Assembler but I am not very good with Arduino yet. Is there an 
easy way to modify the code for 4 digits only?

Any help would be much appreciated.

[neonixie-l] Nixie Clock - Direct Drive HV5530

[Max DN]

Hello,

I'm starting to design my first 6 digit nixie clock and I'd like to use 
direct drive of the tubes (my power supply can take 6 nixies without 
multiplexing).

So far I have built my Nixie watch, coding in ASM, worked on extreme power 
saving etc.

I could multiplex the nixies as I did in this project 
https://fb.watch/eTb69SnxEP/ , but since I have a good power supply I 
wanted to build a clock with direct drive of the tubes.

I prefer to code in ASM (don't ask why :)  ), I could use a 100pin PIC18 to 
drive each digit individually through MMBTA92 & A42 transistors. However, 
if I want to use a PIC with a lower pin count (say 40pins), I may use a 
driver such as HV5530.

Would I still get same brightness as a genuine direct drive as when using 
A92 transistors? I suppose the switching that happens using CLK/SDA on 
the HV5530 is not too different than a good multiplexing. I may be wrong.

And if I were do code ASM to use HV5530, does anyone have sample ASM code? 
I managed to write myself the code to read/write time from an RTC using 
CLK/SDA so I suppose it's very similar but I cannot figure it out from the 
datasheet of HV5530.

Any help is much appreciated.

Max
