1  Using Arduino / LEDs and Multiplexing / Re: AS1130 Ongoing Discussion 132 Individually controllable, PWM LED driver on: March 22, 2013, 11:41:38 pm
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);
