USB to UART Bridges and Their Use in Embedded Systems and IoT
The complexity of a USB interface makes the old school asynchronous serial UART interface attractive to embedded system development. In this video, we show how the USB to UART bridge works, how to install a Windows driver for one of these bridges, and demonstrate a connection to an ESP32 evaluation board using the CP2102 bridge. We also demonstrate the operation of a watchdog timer trying to recover from a non-functioning operating system.
