Microchip公司的PIC32 USB開發(fā)套件具有容易使用和低成本特性,采用32位MCU PIC32MX360F512L,3.3V穩(wěn)壓電源,8MHz晶振,用來(lái)調(diào)試的USB連接,采用PIC18LF4550 USB 微控制器進(jìn)行板調(diào)試,主要用在高度緊湊的圖像/用戶接口,以太網(wǎng)/USB/CAN連接,多任務(wù)嵌入控制和高性能音頻設(shè)備.本文介紹了PIC32 USB開發(fā)工具主要特性,框圖,元件布局圖以及電路圖和材料清單. The PIC32 Starter Kit provides the easiest and lowest cost method to experience the PIC32 microcontroller for the first time. From the over 35 source code examples to the getting started project, users quickly learn Microchip’s 32-bit family of microcontrollers and development tools. The kit includes everything needed to write, program, debug, and execute code on a high performance PIC32 microcontroller. 
圖1. PIC32 USB開發(fā)工具外形圖 The starter kit comes preloaded with demonstration software for the user to explore the new features of the PIC32. It is also expandable through a modular expansion interface,which allows the user to extend its functionality. The starter kit also supplies on-board circuitry for full debug and programming capabilities. The PIC32 Starter Kit contains the following items: • PIC32 Starter Kit Board • USB Mini-B cable PIC32 USB開發(fā)工具主要特性: 1. PIC32MX360F512L 32-bit microcontroller. 2. Green power indicator LED. 3. Regulated +3.3V power supply for powering the starter kit board via USB or expansion board. 4. On-board crystal for precision microcontroller clocking (8 MHz). 5. USB connectivity for on-board debugger communications. 6. PIC18LF4550 USB microcontroller for on-board debugging. 7. Orange Debug indicator LED. 8. Three push-button switches for user-defined inputs. 9. Three user-defined indicator LEDs. 10. Connector for connecting various expansion boards (on the underside of board).
