描述 Description

ET6208/6210/6212 is a 8*8(ET6208), 10*10(ET6210) or 12*12(ET6212) lattice of the LED driver IC with audio 7 band graphic equalizer.
ET6208/6210/6212 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. When normal mode enable, users can achieve 1/8(ET6208) or 1/10(ET6210) or 1/12(ET6212) duty cycle dynamic LED display. 128-step dimming circuitry with PWM configuration and built-in automatic respiratory display function with 7 time steps can help users achieve more colorful patterns.
Users also can freely set the start address, display length and cycles of display frame of built-in 256*8bit(ET6208), 256*10bit(ET6210) or 256*12bit(ET6212) RAM, therefore it cannot occupy many system resources and increase in user’s flexibility of programming.
