Introduction

USB-HS-Bridge v1.3 is a debug tool made by MuseLab based on WCH's CH346C With USB 2.0 High Speed, it support USB-to-UART/SPI Slave/UART/Passive parallel port/GPIO, can be used for a variety of high-speed transmission application

Features

● USB 2.0 high-speed device, 480Mbps bandwidth

● support USB-to-UART/SPI Slave/UART/Passive parallel port/GPIO

● IO level is adjustable, supports 3.3V/2.5V/1.8V/VREF

● Support different working modes

Working Mode

The CH346 development board supports three work modes,  the mode 2 is directly determined by the DIP switch M2. When the DIP switch M2 is turned ON, it switches to Mode 2. When it is turned OFF, it switches to Mode 0 or Mode 1. Mode 0 and Mode 1 can be determined by the dynamic configuration of the host computer software.

Dip Switch Config
DIP switch 1 is used to configure the work mode, and DIP switches 2-5 are used to configure the IO level. Note that DIP switches 2-5 are four-choice switches. When one switch is turned ON, the others must be turned OFF.

How To Use

there is a test demo under doc/CH346EVT/EVT/TOOLS/PC/CH346Demo/ for test with source code.
