Infineon SoC based Bluetooth CYW20820 Bluetooth music light control transmitter solution

1. Bluetooth music light control transmitter solution introduction:

Bluetooth has become part of our life: Bluetooth headset, car Bluetooth, Bluetooth PC accessories, etc.; this time we introduce the Bluetooth music light control transmitter program; now many occasions will use music lights, such as the stage, KTV, music fountain lights, etc., are through the music to control the effect of lighting, different music with different lights, making the atmosphere and music more compatible, more able to create very rich atmosphere, such as soothing music with soft lights; very rhythmic music with intense changing lights;

2. Bluetooth music light control transmitter to achieve the principle of:

Players through the Audio lineout input to the Bluetooth music light control transmitter, through the amplifier to amplify the Audio signal, and then through the ADC to get the Audio amplitude; and then through the Bluetooth to send out the Audio amplitude, the music light received from the light control transmitter command, according to the command control and adjust the music light change (color / brightness / fade, etc.);;
