Contains apk, lib library file (Java Driver), App Demo Example (USB to UART Demo SDK).ĬH9340 datasheet, USB CDC to single serial port, built-in crystal oscillator, supports built-in CDC driver in operating system.Peter Bennett has the right idea, I think.
It provides 8-bit parallel interface, used for MCU 8-UART extension.ĬH340/CH341 USB to serial port Android free drive application library, for Android OS 3.1 and above version which supports USB Host mode already, no need to load Android kernel driver, no root privileges. It supports hardware flow control, compatible with 16C550/16C750. Each UART receive/transmit has independent 128-byte FIFO. CH315H is a USB signal isolation control chip, used for optoelectronic isolator.ĬH438 datasheet. The extension distance of network cable can be up to 300 meters. CH315G is a USB1.1 extension cable control chip. The datasheet is the the description of USB to serial port.ĬH315 datasheet.
Drivers support Windows/Linux/Android/Mac, etc. Used to distribute to the end user with the product.ĬH340 datasheet, USB bus converter chip which realizes USB to serial port/printer port, etc., integrated crystal oscillator, chip information can be customized. The 2-wire interface provides two signal lines SCL and SDA, and supports 4 transmission speeds.ġ.CH341SER.EXE(Windows driver, supports WIN10/WIN8/WIN7/XP etc.)Ģ.CH341SER_ANDROID.ZIP(Android application)ĬH340/CH341 USB to serial port Windows driver, supports 32/64-bit Windows 10/8.1/8/7/VISTA/XP, Server 2016/2012/2008/2003, 2000/ME/98,Microsoft WHQL Certified, supports USB to 3 and 9 wire serial ports.As a Host/Master host, it supports common synchronous serial interfaces such as 2-wire and 4-wire.FlexWireTM technology, enables flexible 2-wire to 5-wire synchronous serial ports through software.Which is similar to the memory read/write mode. The MEM mode provides signals such as A0, RD# and WR# etc.EPP provides signals such as AS#, DS# and WR# etc.Two modes are available: EPP mode and MEM mode.Supports two-way communication of the IEEE-1284 specification and supports one-way and two-way transmission of printers.Supports various standard print port printers, optional low speed printing and high speed printing.Compatible with Windows/Linux/MACOS and so on, and the application is fully compatible.Standard USB print port for upgrading the original print port printer, compatible with the relevant USB specifications.Supports access to the CH341 external serial EEPROM memory in UART communication.through external voltage conversion chip. Provides further RS232, RS485, RS422 interface, etc.Supports UART transmit enable, UART receive ready rate control signals and so on, and common MODEM interface signals.Supports 5, 6, 7 or 8 data bits and 1 or 2 stop bits, supports odd, even, none, mark, space parity.
Hardware full duplex serial UART interface, integrated transmit-receive buffer, supports communication baudrates varies from 50bps to 2Mbps.Original UART applications are totally compatible without any modification.
