我是一名学生，最近在设计一块PIC的板子。在用PICkit2烧录的时候显示：VPP Voltage error. Check target and retry operation.
这个是怎么回事啊？我在Microchip论坛上看到说在VDD和VPP之间连接一个二极管？
我用的是PIC18f14k50,
在MPLAB上的详细信息如下
Found PICkit 2 - Operating System Version 2.32.0
PICkit 2 Unit ID = OlHoss
Target power detected ( 3.43V)
PKWarn0003: Unexpected device ID: Please verify that a PIC18F14K50 is correctly installed in the application. (Expected ID = 0x4760, ID Read = 0x0)
PK2Error0049: VPP Voltage error. Check target and retry operation.
PICkit 2 Ready |
