Get Started with PIC USB Connectivity

摘要

You can add USB to your next project with Microchip Technology's new array of parts. The 8-, 16-, and 32-bit microcontrollers will complement your designs with USB peripheral support, embedded hosting, and dual-role and OTG capabilities. Many of us are just coming to grips with the idea of supporting a USB interface as the communications medium of choice for our product designs. PC manufactures have eliminated the DE9 (standard for years on every PC) and replaced it with USB (and FireWire) connectors. We've been forced to learn more about the protocols than we ever wanted to know. Unless my product incorporates PC-type architecture, I can't take advantage of all the peripherals out there. So, I can forget about adding a storage device, keyboard, or other USB peripheral to my project. Microcontrollers just don't have the room to handle a USB host's responsibilities.
