LC101-HT42B564

 
Overview

本设计是一个USB转换板,采用合泰的USB转换UART芯片HT42B564,一边是usb接口作为HID设备实现与PC机免驱动连接;
为了方便调试,另一边也是USB接口,采用CH340芯片转换为串口,在PC端虚拟串口,从而实现USB与uart双向通信功能;
使用这个小板子,可以让普通没有USB接口的单片机,通过串口转换的方式,作为HID设备连接PC机,即插即用,用途广泛。

The HT42B564-x device is a high performance USB
to UART bridge controller with fully integrated
USB and UART interface functions, designed for
applications that communicate with various types
of UART. The device includes a USB 2.0 full
speed compatible interface which is used for PC
communication. The device also includes a fully
integrated high speed oscillator which is used as clock
source for the USB and UART baud rate generator.
The baud rate generator can support up to 115200bps
of baud rate for the UART interface.
