It's amazing that there are now chips which will drive more than 100 individual LEDs.

When you get that number up to something like half a million LEDs,  you might be
able to invent something like, um, television.

Hey...you should try to market that idea...it might catch on... :smiley-mr-green:

Hi All,

I am working on a project using AS1130 and have problem in making scrolling works. I would like to do scroll of 'digit' accords 5x48 LED using 2 AS1130. (Similar to page 32 of datasheet) . I can already display the 'digit' on the LED matrix, but when I start scrolling, the 'digits' just do not pass the CS11 boundary. Can anyone give me some direction? Thanks in advance.

Follow is the way I am using now:

  as_config(0xc0, 0x0B, 0x02);  //IC1 sync out
  as2_config(0xc0, 0x0B, 0x01); //IC2 sync in

  as_config(0xc0, 0x01, 0x40);  //movie of frame0
  as_config(0xc0, 0x02, 0x01);  //play 1 frame
  as_config(0xc0, 0x03, 0x31);  //scroll digit in 5LED block
  as_config(0xc0, 0x04, 0x2B);  //CS0 to CS11

  //repeat for IC2
  as2_config(0xc0, 0x01, 0x40);
  as2_config(0xc0, 0x02, 0x01);
  as2_config(0xc0, 0x03, 0x31);
  as2_config(0xc0, 0x04, 0x2B);

Whoa.  Can you see out that while it is going?  Add a mode when you can power blast.  Be a superhero!  Also, remake with RGB leds, you could be totally freaky.  I love that.  If that was your idea that is a great one.
I have only come here seeking knowledge. Things they would not teach me of in college.

It doesn't matter if you can see when you look so cool :)

I made some long ago using a traditional strobed matrix approach. These use two AS1130 (on the BGA WL-CSP package) and are way more capable.

Easy to see through them.

Writing code for some RGB ones now :) But those aren't relevant to AS1130.

For anybody who may be interested, I'm porting the existing code over to Raspberry pi
