接下來的時間就要不斷的更新博客了 Im Back !
今天要想大家分享自己寫自己的庫的方法(寫的不對或者有錯誤請指正)
1. 我先把我所說的"模板"的含義說一下:并不是你一開始建立一個專案所建立的專案模板那么簡單,這個模板應該是最小的系統版為基礎的一個可以被你進行短期修改就可以使用在不同專案上的一個庫(當然這個程序是要建立在這個一開始的最小系統板的的專案模板的) 但是一定注意 這些基礎檔案一定要有序和方便易懂,你要知道每個檔案夾是什么意思,存放什么東西 )你可以自己找模板,但是都是大同小異,你對這個模板一定要熟悉,下面是我的模板鏈接
2. 為以后加入的外設做準備,比如加入一些檔案,或者找一些寫的好的函式加進去,這個部分你也可以再寫一個檔案夾來存放
加入Headfile.h的頭檔案放在USER就可以了(里面放你需要的通用的.h檔案,以后就不要經行反復的呼叫了.***注意:不能把外設的.h檔案加進來,一定是通用的***)
math函式檔案(一些數學公式的計算,再一些地方需要用到,你可以自己找更加好的)
3. 把基礎的一些通行或者外設的初始化寫好(比如I2C,USART,SPI,ADC等)
這里你可以把這些初始化寫在相應的外設中,比如你和顯示屏之間通信,你可以把USART所有的介面都定義在一起,然后外設函式呼叫.也可以在外設初始化的時候定義,我個人傾向于前面的那種,但是我也暫時沒有寫出來,因為它確實要對板子十分熟悉,并且要有經驗
4.加入自己的專案的代碼了
勾選那個 C99就可以避免你很多C語言的錯誤(比如在for回圈里進行變數的定義)
你建立一個專案的順序因該是循序漸進:
然后在main函式中進行相應初始化的定義,寫下一個的時候把它再注釋掉,寫完下一個以后解除注釋(這個可以一步步的測驗你的代碼錯誤:比如引腳的重復使用,有些這面定義了別的地方就不行了(一定會深有體會的))
最后就是軟硬體的結合看效果和除錯(先要保證可以實作基礎的功能,細節除錯放在后面.還是第一個博客的哪句畫:先確保代碼沒有問題再找硬體的問題
5.寫說明檔案 但一定注意:這是給別人看的 )
6.總結
1.想建立一個好的庫,你先得進行宏觀的規劃,把每一部分都分類做一個筆記來,然后順著筆記來寫

2.遇到代碼問題要懂得總結:這個問題你可能不是第一次遇到,但是你就是想不起來怎么解決,寫一個檔案去記錄下來(只記住簡單的處理方法就行)
最后是我的一個庫(沒完全寫完)
