host controller interface
    In this paper, the Bluetooth technology is generally introduced, and the emphasis is put on the introduction to Host Controller Interface (HCI).
    本文首先对蓝牙技术进行了概括性的介绍,重点介绍了主机控制器接口(HCI)协议,并对HCI流程进行了剖析。
    While designing the hardware, we use AT9140800 (32-bit embeded MCU) as processor, SL811HS(USB host controller) as host controller. By analyzing the architecture of the chips, the founction of the pins and the read/write timing, the USB host controller interface circuit is accomplished. Depending on it, AT9140800 can operate and control SL811HS.
    在硬件设计上,以AT9140800为处理器(32-bit嵌入式MCU)和SL811HS(USB主机控制器)为主机控制芯片,通过分析芯片结构,引脚信号功能和读/写时序,完成了USB主机控制器接口电路的设计,实现了AT9140800对SL811HS的操作和控制。
