首先確定APP001上的LED燈，LED D1 ~ D8使用到PIC18F45K22那些腳位？
由下圖可知，LED D1 ~ D8接到ERD0 ~ ERD7
而ERD0 ~ ERD7又接到PIC18F45K22的RD0 ~RD7
確認完腳位後就可以開始寫程式了
我想做一個跑馬燈從左至右
首先創建新專案，這部分因為在上一篇有分享，這邊就不重複了
檔名我取Lab1
專案建好後，啟動MCC，先去改包裝，因為我是用DIP
所以Package從UQFN40改成PDIP40
去設定RD0 ~ RD7為GPIO的Output
1.勾選右邊視窗Pin Module
2.Project Resources切到Pin Module
3.Custom Name改名及取消勾選Analog
最後Generate Code
初始化的Code產生完後，會記錄在.c與.h檔內，因此我們要用時需要在自己的程式中include
接下來可以開始寫Lab1所需要的功能了
這邊我發現使用MCC會幫你創建main.c
但若是使用MCC前先自行加入main.c那麼用MCC產生Code之後
就不會在創建main.c了，而是用原先創立的
而使用MCC幫你創建的main.c有一些好處
就是已經幫你include MCC先前創建的code
以及已經在程式開啟後做好初始化了
整段程式寫在main.c
會用到一些函式指標是因為要配合MCC產生的函式呼叫做搭配
的功能
這邊也使用到Timer1幫我做500ms的Delay
同樣也是之前有分享怎麼用MCC產生Timer
這邊也不再重複
