单片机课程设计--步进电机驱动器-毕业设计内容摘要：

R液晶显示步进电机运行状态，其效果比用数码管显示要更加明了，也更容易读取相关状态和数据。 液晶上显示有电机运行的状态、当前 步数 、运行方向以及其运转速度。 其显示原理如下图 42： 图 42 液晶显示流程图 正反转流程图 步进电机的正反转用 K K2控制，初始化电机为顺时针转，即“》”， 每当按下 K4键，电机转向改变，具体流程图如下图 43： 启动与停止流程图 启动与停止是用 K1键来 控制的，初始化标志位 on_off==0,档按下 K1，即将 on_off置 1，每当按下 k1,都将在启动与停止间切换，具体流程图如下图 44： 图 44 启动与停止流程图 第 4 章 硬件设计 硬件的设计与选取 步进电机的驱动 步进电机的驱动采用 ULN2020，接到单片机的 ~，具体如 图 51： 图 51 步进电机驱动及其接口图 单片机的选取 目前市面上的通用型单片机种类很多，且适合不同应用场合的新产品不断出现，但目前的应用状况，以 8位中档 MCS51系列单片机的应用最为普遍。 基于这次课程设计的要求不高，我们可以选用 51系列或 52系列单片机，其有可靠性高，易于扩展以及实用性好等特点，完全可以满足我们的控制要求。 液晶 LCD1602 显示模块 P0接液晶的数据传送口， ~。 其接线图如下图 53： 图 53
