12x11 LED Matrix

The AS1130 is configured to control one big LED matrix.

Figure 24. AS1130 - Dot Matrix Structure

In Table 9 it’s described which databit represents which LED in the matrix. Per default all databits are ‘0’, meaning no LED is on. A ‘1’ puts the

LED on.

Each Current Segment of the LED Matrix consists of 11 LEDs, therefore 2 bytes of data are required for one Current Segment. CS0 is defined by

the two bytes with address 0x00 and 0x01 and also includes the address of the used Blink & PWM dataset for this frame.
