LED灯效驱动

ET6208/6210/6212 是一颗单片集成音频7 段图形均衡器并可驱动8*8(ET6208)，10*10(ET6210)，12*12(ET6212)点阵的LED 驱动电路。ET6208/6210/6212 有音频同步模式和普通模式两种工作模式。在音频同步模式下，通过内置带通滤波器把20Hz~20KHz 的输入音源信号细分为7 个频段，再通过内置的高精度ADC 把每个不同频段的平均幅度值转换成对应的数字值，同时计算出音源信号的总平均幅度值，最后送到输出显示。在音频同步模式下MCU 无须进行任何数据操作，只需要设置相应的指令，LED 灯就可以随着输入音源的频率以及强弱同步显示7 路对应频率的 • 可选择的音频同步模式和普通模式\r\n\r\n• 音频同步模式最少只需发送一条指令，无须 MCU 进行任何的数据操作\r\n\r\n• -18dB~+18dB 音频信号增益可调整\r\n\r\n• 7 段音频均衡器及1 路总音量强弱显示\r\n\r\n• 音频模式下用户可自定义显示幅度对应的阈值\r\n\r\n• 音频模式下用户可以自定义音频同步显示 LED 阵列的排列方式（仅针对ET6210，ET6212）\r\n\r\n• 普通模式和音频模式均可以实现 128 阶亮度等级\r\n\r\n• 内置 256*8bit(ET6208)，256*10bit(ET6210)，256*12bit(;
