其實(shí)這程序的難點(diǎn)就是怎么樣處理計(jì)數(shù)器中斷清零時(shí)帶來(lái)的負(fù)面情況......樓主再看一下就清楚了.......我講的虛擬計(jì)數(shù)器就是給每個(gè)經(jīng)過(guò)檢料開(kāi)關(guān)工件定個(gè)開(kāi)始計(jì)數(shù)器和結(jié)束計(jì)數(shù)器....這些計(jì)數(shù)器的值是從高速計(jì)算器那里得來(lái)的.....但它不會(huì)受高速計(jì)數(shù)器中斷清零時(shí)的影響,,,,,它會(huì)一直累積著計(jì)數(shù)值,,直到這個(gè)工件完成全部工序時(shí)才復(fù)位清零后循環(huán)再用......樓主應(yīng)該明白了吧.......不復(fù)雜的......
師付，能否講得詳細(xì)點(diǎn)，或者舉個(gè)實(shí)例，
“虛擬計(jì)數(shù)器就是給每個(gè)經(jīng)過(guò)檢料開(kāi)關(guān)工件定個(gè)開(kāi)始計(jì)數(shù)器和結(jié)束計(jì)數(shù)器....”這個(gè)開(kāi)始和結(jié)束計(jì)數(shù)器用什么
計(jì)數(shù)器啊？
