ROM和RAM指的都是半導體儲存空間,ROM是Read Only Memory的縮寫,RAM是Random Access Memory的縮寫。ROM在系統停止供電的時候仍然可以保持資料,而RAM通常都是在掉電之後就遺失資料,典型的RAM就是電腦的記憶體。 RAM 有兩大類,一種稱為靜態RAM(Static RAM/SRAM),SRAM速度非常快,是目前讀寫最快的存放裝置了,但是它也非常昂貴,所以只在要求很苛刻的地方使用,譬如CPU的一級緩衝,二級緩 沖。另一種稱為動態RAM(Dynamic R
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

——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
