我刚接触PIC ，装了开发环境和18c编译器后做了最简单的一个工程。编译的情况应该是正确的，烧写是有如下问题：
ICDWarn0068:
This device has a VPP(max) below the minimum ICD2 VPP level of 12V.
Please ensure that external protection for MCLR is in place.
(Press the Help button for an example circuit or use AC164112 available from microchipDIRECT.com.)

望各位锅炉的朋友帮我看下问题。 |
