Figure 28. Audio controlled LED digital processing internal circuit

These three output channels (ch1, ch2, ch3) can be routed to any of the current sources according to Figure 27.

The digital processing can be done in two different operating modes (defined by the register bit freq_mode):

8.8.1

Amplitude Mode

This mode is selected by freq_mode=0.

The input amplitude is mapped into different colors for RGB LED(s) or brightness for single color LED(s). The mapping

is controlled by the register audio_color. If audio_color = 000, then the mapping is done as follows:

Very low amplitudes are mapped to black, for higher amplitudes, the color smoothly transitions from blue, green, cyan,

yellow, red and eventually to white (for high input amplitudes).
