Overview

Many devices formerly connected via UART have been equipped with USB interfaces using serial to UART converters such as the CP210x USB-to-UART Bridges from Silicon Labs. emUSB-Host is capable of easily addressing such devices.

USB to TTL
A USB to UART bridge typically contains an CP210x chip which performs data translation.

Key features

  • Compatibility with different CP210x devices
  • Ability to send and receive data
  • Ability to set various parameters, such as baud rate, number of stop bits, parity
  • Handling of multiple CP210x devices at the same time
  • Notifications about CP210x connection status
  • Ability to query the CP210x line and modem status
  • Small footprint

Application Samples emUSB-Host CP210x

USB to TTL

CP2102 USB to UART Bridge

Compatibility

The following devices were tested with the current CP210x driver:

  • CP2102
  • CP2103
  • CP2104

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 CP210x 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.

Requirements

Components required to use emUSB-Host CP210x:

  • emUSB-Host CP210x
  • 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)
