有詳細的么。

感覺很不錯誒，最近剛開始學(xué)習(xí)ADF4351模塊，還有很多地方不懂，作者大大的這個挺有參考價值的

是C文件里面數(shù)4行下面的程序嗎把程序加進去就行了嗎

樓主的這個diam估計是從他自己的工程項目中提取取出來,又沒有說是什么MCU芯片的,你得移植進你的項目,你用的是什么單片機?得改一下delay,把ADF4351.c里面該去掉的全都去掉,然后加入你自己的main()才行,樓主的文件只是一些函數(shù)而已,你得自己在main里面調(diào)用這些函數(shù),實現(xiàn)你自己的功能,說白了就是復(fù)制粘貼然,然后用你自己的思路來組合,以便實現(xiàn)你需要的功能.你可能需要一個完整的實例來參考學(xué)習(xí),論壇里面有人上傳這個芯片的430MCU的工程,你可以參考一下:http://www.zg4o1577.cn/bbs/dpj-99871-1.html
