    Overview

    Many devices formerly connected via UART have been equipped with USB interfaces using serial to UART converters such as the FTDI UART and FT-X devices from FTDI. emUSB-Host is capable of easily addressing such devices.

    ftdi
    A USB to RS-232 converter typically contains an FTDI chip which performs data translation.

    Key features

    • Compatibility with different FTDI UART devices
    • Ability to send and receive data
    • Ability to set various parameters, such as baud rate, number of stop bits, parity
    • Handling of multiple FTDI UART devices at the same time
    • Notifications about FTDI UART connection status
    • Ability to query the FTDI UART line and modem status
    • Small footprint

    Requirements

    Components required to use emUSB-Host FTDI UART:

    • emUSB-Host FTDI UART (Included in emUSB-Host PRO package)
    • emUSB-Host core (Included in emUSB-Host PRO package)
    • emUSB-Host target driver (One driver is included in emUSB-Host PRO package)
    • Real-time operating system (embOS or other)

    Resource usage

    Example Code Included

    An example application which uses the API is provided with any shipment or eval software including emUSB-Host. This example displays information about the FTDI UART device in the I/O terminal of the debugger. In addition the application then starts a simple echo server, sending back the received data. Several application samples can also be found on the emUSB-Host sample page.

    Compatibility

    The following devices were tested with the current FTDI UART driver:

    • FT8U232AM
    • FT232B
    • FT232R
    • FT2232D
    • FT231X
    • FT230XQ
