About CP210x

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.

Application Samples emUSB-Host CP210x

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.
