README.md Implementing USB communication device class (CDC) on EFM32 MCUs 1. Introduction USB revolutionized the PC peripheral space by making a very simple plug-and-play interface for users. As a result, many modern computers no longer support RS-232 serial COM ports, opting for the slimmer USB alternative.

This can be an issue for the developer who needs a COM port for communication between a peripheral and host PC. A subset of the USB Communication DeviceClass (CDC) can be used to emulate a serial port providing a virtual COM port UART interface. This allows developers to use legacy applications with new products using the same COM port interface as before, with few hardware and software modifications. Figure 1 USB CDC Virtual COM Port System This application note describes the USB communications device class driver (or USB CDC) in detail and includes an implementation example for the Silicon Labs EFM32 MCU. Assumptions This document assumes the following: • A working knowledge of the C programming language. How To Install En Focus Pitstop Pro 12 Crack on this page. Software Wifi Hacker. • Familiarity with the USB 2.0 specification and terms and abbreviations defined by the USB specification. Live Interior 3d Pro 2.8 Mac Osx Torrent.
