Topic: AS1130 Ongoing Discussion 132 Individually controllable, PWM LED driver (Read 47475 times) previous topic - next topic


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:
I'm allowed to have it 'cos it's not sharp.


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 will never ask you to do anything that I wouldn't do myself.


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.

Oh wow! Did you make those glasses yourself?
Code, codeeeeee

For anybody who may be interested, I'm porting the existing code over to Raspberry pi
Accelerate to 88 miles per hour.


Hi folks, sorry to resurrect an old thread. I read through this and did not see that this question was asked:

Once set up, and while running, does the AS1130 permit you to make changes to the PWM and/or frame(s) without a reset?

For example, can I address a single LED in the PWM table and alter its brightness?

Or does the AS1130 just play static frames?



Hi folks, I confirmed that the pwm, blink and on/off parameters can be tweaked on the fly without requiring a reset of the AS1130.
