The CDC RS-232 Emulation Demo by Microchip Technology showcases the implementation of the Communication Device Class (CDC) specification for USB-to-serial communication. It enables a microcontroller or embedded system with USB capabilities to emulate an RS-232 serial port over USB. This demo establishes a virtual COM port on a host device, such as a computer, allowing bidirectional serial communication. By encapsulating serial data and control signals using the CDC protocol, the demo enables seamless integration with legacy serial communication systems. Microchip provides example code, firmware, host-side driver software, and documentation for developers to implement CDC RS-232 emulation in their own projects. This demonstration simplifies the integration of USB-enabled devices into systems relying on RS-232 communication, offering a flexible and convenient solution.
