步进电机红外遥控C语言程序,单片机红外遥控+步进电机+1602液晶显示c语言源程序...
這是我做的紅外遙控控制的1602顯示轉(zhuǎn)速和轉(zhuǎn)向的步進(jìn)電機(jī)c語言原程序,已經(jīng)調(diào)試成功！有些模塊是以前做其他實驗時做的，現(xiàn)在是直接調(diào)用的,包括1602液晶顯示技術(shù),TC9012紅外解碼,然后就是四相步進(jìn)電機(jī)的控制程序了,我是把這些東西結(jié)合起來。對這個東西有興趣的或者要做畢業(yè)設(shè)計的可以看看啊,不懂的請上單片機(jī)論壇http://www.51hei.com/bbs/ 公開討論，我會給大家做出詳細(xì)的解答。
