This tutorial provided an overview of USB technology, its components, and the steps involved in configuring a PIC microcontroller as a USB device. It also explained the necessary circuitry and programming code needed to establish USB communication.

2012年9月4日 · Microchip has provided almost all of the code and examples to run USB code on PIC chips. This code is called the USB stack, and we will use this as the main library for communicating to PCs. Unfortunately, there are a few bugs for certain PIC chips and some quirks to getting the libraries setup in MPLAB.

Usbpicprog is an USB in circuit programmer for Microchip PIC processors. The hardware is as simple as possible, the current version only contains one PIC18F2550, 4 mosfets, and besides the connectors a hand full of passive components.
