LED address mapping

Default is constant brightness control with 14/16 pulse width.

During normal operation, the user defined value will be stored in the respective location.

8.3.1

Display setting (maximum number of digits):

The 3-bit values corresponding to selection of number of digits of display are shown below:

000: 1 digit 8 segments

001: 2 digits 8 segments

010: 3 digits 8 segments

011: 4 digits 8 segments

100: 5 digits 8 segments

101: 6 digits 8 segments

Select the number of digits by writing the value in page 0x10 and the address 0x00 in LSB2

to LSB0.

8.3.2

Dimming setting (brightness levels):

The 4-bit values corresponding to different brightness levels are shown below:

0000: pulse width is 1/16

0001: pulse width is 2/16

0010: pulse width is 4/16

0011: pulse width is 10/16

0100: pulse width is 11/16

0101: pulse width is 12/16

0110: pulse width is 13/16

0111: pulse width is 14/16

Set the dimming timing (write into respective address location from 0x00 to 0x03; page 0x10

& 0x11).
