在MPLAB IPE V4.05中使用PACKIT3加载新PIC18F65 K40 IC中的十六进制代码时出现以下错误。在所有论坛中,我发现硬件出现错误的可能性,但我已经尽可能多地检查了我的硬件。我怀疑在IC,请任何人给我一个建议或解决方案。当连接我的硬件与PACtiT3我得到:目标电压检测目标设备ID(0xFFFF)是一个无效的设备ID。请检查您的连接到目标设备。即使目标设备没有发现我试图编程它然后我OT:下面的内存区域将被编程:程序存储器:开始地址=0x0,结束地址=0x7FFFULID内存程序地址:0预期值:Eff7接收值:FFFFAST失败到程序设备
以上来自于百度翻译 以下为原文 The following error was appeared while loading hex code in fresh pic18f65k40 IC using pickit3 in MPLAB IPE v4.05. In all forums i found that the possibility of errors occur in hardware but I've checked my hardware at most possible ways. I doubted in IC, please anyone give me a suggestion or solution. When connecting my hardware with pickit3 i got: Target voltage detected Target Device ID (0xffff) is an Invalid Device ID. Please check your connections to the Target Device. Even the target device not found i tried to program it then i got: The following memory area(s) will be programmed: program memory: start address = 0x0, end address = 0x7fff User Id Memory program memory Address: 0 Expected Value: eff7 Received Value: ffff Failed to program device |

很明显,这不是和PIC对话。你确定PGD和PGC引脚是否正确连接,没有什么能阻止MCLR被拉到VDD之上?
以上来自于百度翻译 以下为原文 It's plainly not talking to the PIC at all. Are you sure you have the PGD and PGC pins connected correctly, and that there is nothing preventing MCLR being pulled above Vdd? |
