Using L298 as the drive to control two
用L298作为驱动器,控制两相混合式步进电机。
按键从上至下分别为减速,加速,正转,反转,停止。
具体参数还没有设定过。速度有些慢,加速按2下有效,然后就不能再快了。
转速输出是按照最小系统版的数码管写的。电路图里太麻烦就没画了。-Using L298 as the drive to control two-phase hybrid stepping motor. Buttons from top to bottom respectively, deceleration, acceleration, are being transferred, reverse, stop. Specific parameters have not yet been set. Some of the slow speed, speed up by 2, effectively, and then can not be faster. Speed output is in accordance with the minimum system version of the digital tube wrote. Circuit where not too much trouble drew.

pic单片机
DB4~DB7:在L CD中的作用,为数据线,DB0~DB2接地,DB3接高电平以完成对液晶的初始化。本Demo例子程序中,与单片机的RB2~RB5连接,用户使用其他的管腿时,只需修改#define部分。
RS为数据、指令控制线,与单片机的RB1连接,当RS为高电平时对LCD模块数据寄存器操作,当RS为低电平时对LCD模块指令寄存器操作;
E为读写使能控制线,与单片机的RA5连接,每当E线向LCD模块发送一个正脉冲,LCD模块与单片机之间将进行一次数据交换;
A、K分别是LCD模块背光的正负电源引脚,1-1所示,我们将用RC2控制背光,改变R29的值将改变背光亮度
R/W为读写选择线,在ICD2DEMO教学实验板中,R/W线接地,只做对LCD模块的写操作
-pic Singlechip DB4 ~ DB7: in the role of L CD for the data lines, DB0 ~ DB2 grounding, DB3 then high in order to complete the initialization of the LCD. Examples of this Demo program, with the single chip RB2 ~ RB5 connection, the user to use other s legs, simply amend the
