/******************************步進(jìn)電機(jī)的驅(qū)動(dòng)*************************************
程序名稱: 按鍵控制電機(jī)正反轉(zhuǎn),LCD1602顯示正反轉(zhuǎn)
說(shuō)明:使用本程序你必須把 SE5設(shè)置為ON(2-3)短接
;FOSC = 12MHz
;---------------------------------------------------------------------------------
; 步進(jìn)電機(jī)的驅(qū)動(dòng)信號(hào)必須為脈沖信號(hào)!!! 轉(zhuǎn)動(dòng)的速度和脈沖的頻率成正比!!!
; 本步進(jìn)電機(jī)步進(jìn)角為 5.625度 . 一圈 360 度 , 需要64個(gè)脈沖完成!!!
;---------------------------------------------------------------------------------
; A組線圈對(duì)應(yīng) P1.4
; B組線圈對(duì)應(yīng) P1.5
; C組線圈對(duì)應(yīng) P1.6
; D組線圈對(duì)應(yīng) P1.7
; 正轉(zhuǎn)次序: AB組--BC組--CD組--DA組 (即一個(gè)脈沖,正轉(zhuǎn)5.625度)
