常见问题
数据协议采用单线归零码的通讯方式,芯片在上电复位以后,DIN端接收从控制器传输过来的数据,首先送过来的32bit数据被第一个芯片提取后,送到芯片内部的数据锁存器,剩余的数据经过内部整形处理电路整形放大后通过DO端口开始转发输出给下一个级联的像素点,每经过一个像素点的传输,信号减少32bit。芯片采用自动整形转发技术,使得该像素点的级联个数不受信号传送的限制,仅仅受限信号传输速度要求。
芯片内部的数据锁存器根据接收到的32bit数据,在OUTR、OUTG、OUTB、OUTW控制端产生不同的占空比控制信号,等待DIN端输入RESET信号时,所有芯片同步将接收到的数据送到各个段,芯片将在该信号结束后重新接收新的数据,在接收完开始的32bit数据后,通过DO口转发数据口,芯片在没有接受到RESET码前,OUTR、OUTG、OUTB、OUTW管脚原输出保持不变,当接受到280μs以上低电平RESET码后,芯片将刚才接收到的32bitPWM数据脉宽输出到OUTR、OUTG、OUTB、OUTW引脚上。
提供SOP8封装。
主要特点
R、G、B、W输出端口耐压20V,DIN端口耐压9V。
