# **WCH USB 配置工具 CH34xSerCfg 使用说明** ## **一、概述** CH34xSerCfg配置软件用于WCH USB转串口系列芯片进行USB参数配置，通过该工具可对芯片的厂商识别码VID、产品识别码PID、最大电流值、BCD版本号、厂商信息和产品信息字符串描述符等参数进行修改配置。 程序支持配置型号：CH343P、CH342F、CH347T/F、CH344Q/L、CH348Q/L、CH9101U/H/R/Y、CH9102F、CH9103M、CH9104L。 （注：CH342F/CH9102F批号倒数第4位是字母的芯片,则内置EEPROM可支持此配置功能。） ## **二、CH34xSerCfg 功能说明** 本节对 CH34xSerCfg 软件功能进行说明，使用前需安装对应产品VCP驱动和应用库，下载链接： [GitHub - WCHSoftGroup/ch343ser_linux: USB driver for USB to serial chip ch342, ch343, ch344, ch9101, ch9102, ch9103, etc](https://github.com/WCHSoftGroup/ch343ser_linux) [GitHub - WCHSoftGroup/ch9344ser_linux](https://github.com/WCHSoftGroup/ch9344ser_linux) ### 1、填写配置项 在CONFIG.INI文件中填写需要修改的配置项，**不需要修改的配置项可不用填写**。 | **配置项** | **说明** | 可选值/注意事项 | | :--------------------------: | :----------------------------: | :----------------------------: | | **VendorID** | 厂商识别码 | 使用合法ID | | **ProductID** | 产品识别码 | 使用合法ID | | **MaxPower(HEX)** | 最大电源电流值 | 以2mA为单位，填十六进制 | | **PowerMode** | USB供电方式 | Self-Powered或Bus-Powered | | **Wakeup_Enable** | 睡眠唤醒功能 | 1：开启 0：关闭 | | **CDC_CTSRTS_FlowControl** | CDC模式下是否启用硬件流控 | 1：开启 0：关闭 | | **EEPROM_Disable** | 禁用eeprom默认配置 | 1：禁用 0：开启 | | **TNOW_DTR_SoftSet** | TNOW/DTR引脚功能配置 | 1：开启 0：关闭 | | **CH9101RY_MODEM_Enable** | CH9101R/Y芯片MODEM引脚功能配置 | 1：开启 0：关闭 | | **CH9101RY_DSR_MUX_TXS** | CH9101RY DSR#脚功能 | 0:TXS功能(默认) 1: DSR#功能 | | **CH9101RY_RI_MUX_RXS** | CH9101RY RI#脚功能 | 0:RXS功能(默认) 1: RI#功能 | | **CH9101RY_DCD_MUX_TNOW** | CH9101RY DCD#脚功能 | 0:TNOW功能(默认) 1: DCD#功能 | | **CH9101RY_DTR_MUX_SUSPEND** | CH9101RY DTR#脚功能 | 0:SLEEP功能(默认) 1: DTR#功能 | | **Serial_String** | USB设备序列号字符串 | 长度范围0~24字节 | | **Product_String** | USB产品信息字符串 | 长度范围0~40字节 | | **Manufacturer_String** | USB厂商信息字符串 | 长度范围0~40字节 | **注意事项**： - 修改设备的 VID 或 PID 后，原 VCP 驱动将不再适用于该硬件，设备此时只能使用系统自带 CDC 驱动（CH340/CH348 系列不支持系统 CDC 驱动），若需要使用 VCP 驱动，需在驱动static const struct usb_device_id xxx_ids[] 结构体数组中，增加对应的ID匹配项，重新编译、加载驱动。 - 不要修改CONFIG.INI文件中除配置项外的其他内容或格式。 ### 2、编译和执行示例 - 从ch343ser_linux和ch9344ser_linux资料的lib文件夹中获取libch34xcfg.so(.a)、libch343.so(.a)和libch9344.so(.a)库文件，将库文件放置到系统标准库路径下或者param_config目录，将lib文件夹下所有头文件也拷贝至param_config目录； - 进入param_config目录下，执行命令：gcc ch34x_demo_param_config.c -lch34xcfg -lch343 -lch9344 -o CH34xSerCfg - 命令格式1：./CH34xSerCfg [串口设备路径] ​ 输入g：获取当前配置 ​ 输入s：配置芯片 ​ 输入r：向EEPROM写入厂商默认配置 ​ 输入q：退出程序 ### 3、使用示例 执行程序 sudo ./CH34xSerCfg /dev/ttyCH343USB0 配置文件 ```shell [Public] VendorID= ProductID= MaxPower(HEX)=40 PowerMode=Bus-Powered Wakeup_Enable=1 CDC_CTSRTS_FlowControl=1 EEPROM_Disable=1 TNOW_DTR_SoftSet=1 CH9101RY_MODEM_Enable=1 CH9101RY_DSR_MUX_TXS=0 CH9101RY_RI_MUX_RXS=0 CH9101RY_DCD_MUX_TNOW=0 CH9101RY_DTR_MUX_SUSPEND=0 Serial_String=abcdeabcde Product_String=USB Single Serial Manufacturer_String=www.wch.cn ``` 配置示例： ```shell press g to get usb config, s to set usb config, r to set default config, q to quit this app. s CINFIG.INI [VendorID] null CINFIG.INI [ProductID] null Update [MaxPower(HEX)] >>>>>>>>> [0x40].
