AS1119

Datasheet - Regi s t er Description

3 Blocks with 5x6 LED Matrix

The AS1119 can be configured to control three seperated blocks of LEDs matrixes. This must be set via the bit D0 in the AS1119 config register

(see AS1119 Config Register (0x04) on page 24)

.

Figure 22. 5x6 LED Matrix with 3 Matrixes

In Table 12 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.

Note:

LED A01 is the first LED of the Current Source 0 in the Matrix A. LED B01 is the first LED of the Current Source 6 in the Matrix B. and

so on.
