Using the I2C Bus Judging from my emails, it is quite clear that the I2C bus can be very confusing for the newcomer. I have lots of examples on using the I2C bus on the website, but many of these are using high level controllers and do not show the
1.修改上一級目錄 Kconfig 加入如下代碼: source "drivers/char/fake_driver/Kconfig" 如果你的上一級目錄跟我不一樣需要修改Kconfig 路徑2.修改該你原始碼所在檔案 Kconfig (如果沒有建立一個Kconfig檔案) 例子如下: # fake driver for linux test menu "Fake driver" comment "I am a fake driver list, do noting!"

有時system.map檔案可以協助我們理解核心編譯,它記錄了所有代碼的運行地址。下面一起看看如何讀懂它system.map內容格式為:線性地址 類型 符號具體內容如下: 00100000 A phys_startup_32c0100000 T startup_32c0100000 A _text 注:表示核心代碼第一個位元組的地址c01000c6 t checkCPUtypec0100147 t is486c010014e t is386

1. The software must be conformed to its new vehicles of opportunity.2. Inference engine technology is developed in an application-independant way, and then applied to many uses. One can justify much more effort on the inference engines.Indeed,
——彭曉林 問題出現環境:當你刪除工程裡面的xxx.cpp檔案時候,重新編譯就會出現 “No rule to make targets xxx” 出現原因:由於檔案刪除了,但是工程檔案認為xxx.cpp檔案還存在,在編譯的時候繼續尋找xxx.cpp檔案,結果可想而知,當然是找不到xxx.cpp檔案,結果就是報告上面的錯誤。 解決方案:找出工程相關記錄xxx.cpp地方刪除。(我找了好一會才找到,起初刪除debug檔案,怎麼都不管用,後來
