General Description
ET6212 is a 12*12 lattice of the LED driver IC with audio 7 band graphic equalizer.ET6212 have two kinds of working mode, audio synchronization mode and normal mode. When audio synchronization mode enable, the input audio signal is divided into 7 bands through the built-in band-pass filter, then the 7 filtered analog audio signals and one volume signal are converted to digital signal through the built-in high-precision ADC, and display. In audio synchronization mode, MCU does not need any data manipulation, only one instruction is needed to send.Display length and cycles of display frame of built-in 256*12bit RAM, therefore it cannot occupy many system resources and increase in user’s flexibility of programming.
