Re: How you directly access serially chained devices, like LEDS, shift registers, etc

Since the LEDs effectively ARE shift registers daisychained together there is no way to update a single LED, you doneed to refresh the complete string. But if you design a 192x12 display you could,...

ht16k33 was just an example, note the "or similar" in my post - I don't exactly remember which holtek chip has individual brightness control, but there are some, they're installed in these commercial...

Re: How you directly access serially chained devices, like LEDS, shift registers, etc

It is not about what can run what, it is about efficiency.
As another solution, I think, led decoders like HT16K33+discrete RGB LED or similar can be used.

The 5x6 grid is not very roomy for good fonts. After a bit of experimenting I ended up with the rectangular fonts that follow. I thing they are readable from longer distance.

Re: How you directly access serially chained devices, like LEDS, shift registers, etc

Actually, I'm not doing anything so far, just in future, I want to make a small RGB display, 192 X 12 pixels, using these LEDs. My experience with 64x8 LED displays, based on 4 x MAX7219 was not so...

Re: How you directly access serially chained devices, like LEDS, shift registers, etc

From what I've read, if you're running 256 LEDs, you get them where you want them now, but to change #240 requires shooting out 256 color commands. Is this your only option, or might there be...

How you directly access serially chained devices, like LEDS, shift registers, etc?

Hello.

I connected 6 pieces of APA102C to 16F886 and they all work fine, control appears to be quite straightforward and simple:
