MODE CONTROL IN FREQUENCY MODE
Mode control has two setups based on audio synchronization mode select: the frequency mode and the amplitude mode. During
the
frequency mode
user can select two filter options by MODE_CTRL as shown below. User can select the filters based on the
music type and light effect requirements. In the first mode the frequency range extends to 8 kHz in the secont to 4 kHz.
The lowpass filter is used for the red, the bandpass filter for the blue and the hipass filter for the green LED.
Higher frequency mode
MODE_CTRL = 00 and SYNC_MODE = 1
30023827
Lower frequency mode
MODE_CTRL = 01 and SYNC_MODE = 1
30023828
MODE CONTROL IN AMPLITUDE MODE
During the
amplitude synchronization mode
user can select between three different amplitude mappings by using
MODE_CTRL select. These three mapping options give different light response. The modes are presented in the following graphs.
Non-overlapping mode
MODE_CTRL[1:0] = [01]
30023829
Partly overlapping mode
MODE_CTRL[1:0] = [00]
