  • 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.
