程序從頭到尾認(rèn)真研究與學(xué)習(xí)了一下，就程序整體邏輯而言，個人以為還是不錯的，但是其中有一處個人以為還可以進(jìn)一步優(yōu)化，其中正常顯示的邏輯中，關(guān)于里程的存儲處理函數(shù)SETS();，放在if(Mode==0&&bike_set==0)中，具體見下屬函數(shù)，會導(dǎo)致里程存儲過于頻繁，對于FLASH是一種考驗(yàn)，又因?yàn)楸境绦虻倪壿嬛�，測速計(jì)算處于定時器中斷中，每隔500ms才計(jì)算一次速度及里程數(shù)據(jù)，所以更沒有必要那么頻繁的存儲里程數(shù)據(jù)。還有其中的/40注釋沒有說明，其實(shí)我以為就是前面別人所說的磁極脈沖數(shù)。個人見解歡迎批評指正，謝謝。
