大神好，我想問(wèn)問(wèn)這個(gè)速度和里程的代碼具體可以解釋一下嗎  沒(méi)看懂

if(m>=10)
      {
            m=0;
            Mileage=Mileage+10*(Velocity/3.6)/2;                //里程m=里程+速度km/h/3.6/2
            Velocity=count *2*3.14*RADIUS /100000*2*3600  /40;//將500ms的距離經(jīng)過(guò)運(yùn)算得到km/h，將速度/100，方便顯示
            count=0;
      }
}

終于弄明白了，那個(gè)除以40是樓主隨便寫的樣，我沒(méi)有要，參考樓主朋友的程序，我打算用在電動(dòng)車?yán)锍瘫砩�，所以將安全速度改成了加脈沖個(gè)數(shù)設(shè)置了，使每圈的磁極脈沖個(gè)數(shù)與輪半徑都參與里程與速度關(guān)連了，仿真沒(méi)有問(wèn)題了等有空做個(gè)實(shí)物出來(lái)試試看到底行不行了。
if(m>=10)
{
m=0;

Mileage=Mileage+count*2*3.14*RADIUS/maicong/10;//里程數(shù)mileage=里程+記數(shù)值*輪周長(zhǎng)/每圈磁極對(duì)數(shù)/10
Velocity=count *2*3.14*RADIUS/maicong/100000*2*3600 ;//velocity是速度，將500ms的距離經(jīng)過(guò)運(yùn)算得到km/h，方便顯示
count=0;

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(gè)人以為還是不錯(cuò)的，但是其中有一處個(gè)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(chǔ)處理函數(shù)SETS();，放在if(Mode==0&&bike_set==0)中，具體見(jiàn)下屬函數(shù)，會(huì)導(dǎo)致里程存儲(chǔ)過(guò)于頻繁，對(duì)于FLASH是一種考驗(yàn)，又因?yàn)楸境绦虻倪壿嬛�，測(cè)速計(jì)算處于定時(shí)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(méi)有必要那么頻繁的存儲(chǔ)里程數(shù)據(jù)。還有其中的/40注釋沒(méi)有說(shuō)明，其實(shí)我以為就是前面別人所說(shuō)的磁極脈沖數(shù)。個(gè)人見(jiàn)解歡迎批評(píng)指正，謝謝。

版主能否解釋一下里面的參數(shù)

Mileage=Mileage+10*(Velocity/3.6)/2; //里程m=里程+速度km/h/3.6/2
Velocity=count *2*3.14*RADIUS /100000*2*3600 /40;//將500ms的距離經(jīng)過(guò)運(yùn)算得到km/h，將速度/100，方便顯示
