Single-chip dual-ambience lamp music beat control method, system and electronic device

Abstract

The present application relates to a kind of single-chip dual atmosphere lamp music rhythm control method, two atmosphere lamp beads are provided in each lamp holder and are driven by single lamp holder chip, the method comprises: S1.music signal is collected to the music played by car control module, the energy information of multiple frequency bands is calculated by the mel-frequency spectrum diagram of each frame signal, and light effect mode is selected by car control module;S2.the energy information, light effect mode instruction is encapsulated into LIN signal by CAN conversion LIN gateway module, and is issued to each lamp holder chip;S3.corresponding relationship of the frequency band and color is pre-stored in the lamp holder chip, after the lamp holder chip receives LIN signal, the color and brightness information of each lamp bead are obtained by interpolation and look-up table processing in combination with the slave node address of lamp holder, to drive atmosphere lamp work.The present application has the advantages of low communication delay, low hardware cost, and various atmosphere lamp modes.
