申请了一块PIC18F47Q10-CNANO KI的评估板，Made in Malaysia，使用开发环境MPLAB X IDE V5.4 + XC8 V2.2，都是官方最新的版本。可能笔记本装的开发环境太多，把评估板接上电脑之后，一直无法找到，显示驱动问题，无耐，升级了相关开发环境，升级完成之后，记的一定要在PACKS这个页面，把开发工具相关的Device Family Packs中的升级包安装一下，包含PIC18F47Q10,ATSAMD21相关的升级包都安装一下，否则，MPLAB无法连接评估板。
资料下载地址：
MPLAB X IDE V5.4 有win,linux,mac三种平台的版本 https://www.microchip.com/mplab/mplab-x-ide
MPLAB® XC8 Compiler v2.20 https://www.microchip.com/mplabxc8windows
PIC18F47Q10官方相关资料 https://www.microchip.com/wwwproducts/en/PIC18F47Q10
无法识别评估板会出如下内容：
如果不能一次连接成功，需要手动查找安装相关驱动包：
相关驱动安装完成之后，出现如下内容，设备管理器中会出现MICROCHIP TOOLS的设备，还会出现一个串口设备，电脑中显示多了一个U盘，1M大小。
新建一个工程，芯片选PIC18F47Q10，开发工具选 Curiosity Board: PIC18F47Q10 Curiosity Nano，编译器选XC8，输入新工程的名字，工程建完之后，在source files中建一个main.c的文件就可以了。
main.c例程如下，一个让指示灯闪烁的代码，这个是用TIMER1做的定时器，参考网友代码，调试通过：
