可以用了，謝謝。

那你有賞網抓下且看過PICKit 3 的使用手冊嗎?

我是新手，我也遇到這個問題一直沒辨法解決，
BUILD SUCCEEDED 是OK，
但是用電路板就不行，有沒有高手可以指導一下，
我的電路板是APP025, 範例是曾百由的書。謝謝。

在 MPLAB IDE 下列出十種最有可能的錯誤:

Top 10 Reasons Why You Can't Debug
1. The oscillator is not working. Check your Configuration bits setting for the oscillator.
2. The target board is not powered. Check the power cable connection.
3. The debugger has become physically disconnected from the PC and/or the target board. Check the communications cables' connections.
4. The device is code-protected. Check your Configuration bit's setting for code protection.
5. You are trying to rebuild the project while in Release mode. Select Debug in the Build Configuration drop-down list on the project toolbar, then rebuild the project.
6. The debugger is selected as a programmer, and not as a debugger, in MPLAB IDE.
7. The debugger to PC communications has been interrupted. Reconnect to the debugger in MPLAB IDE.
8. The target application has become corrupted or contains errors.Try rebuilding and reprogramming the target application. Then initiate a Power-on Reset of the target.
9. Other configuration settings are interfering with debugging. Any configuration setting that would prevent the target from executing code will also prevent the debugger from putting the code into debug mode.
10. The debugger cannot always perform the action requested. For example, the debugger cannot set a breakpoint if the target application is currently running.
