A USB to UART bridge typically contains an CP210x chip which performs data translation.
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.
The following devices were tested with the current CP210x driver:
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.
