点阵字体产生工具以及相关显示函数。
在开发嵌入式系统时,需要显示不同大小或类型字体的汉字。显然,对于嵌入式系统,不太可能使用矢量字体,而点阵字体,不同大小的字体不能简单的缩放。 另外,对一个小系统,也不需要完整的字体,往往只要几十个,甚至几个就够了。
一般,我们采用的方法是,自己准备点阵字体的数据,在显示汉字时,把这些数据写入显存就行了。 这时又存在另外一个问题,由于是不完整的字库,不能简单的用汉字的内码去找到对应的字体数据,如果逐个比较,又费时间。比较好的方法就是把字体数据排序,用二分法查找,这样可以大大提高查找效率。
这里为以上问题提供了一个完整的解决方案:
产生字体数据:指定字体类型、大小,自动产生字体数据。
字体数据排序:可以按Unicode,也可以按Ansi排序。
集成显示函数:提供相关显示函数。为了节省空间,我们把文字分成thin和wide两种,前者用于显示传统的ASCII字符集,后者用于显示汉字等多(双)字节字符

按键 步进电机
步进电机是将电脉冲信号转变为角位移或线位移的开环控制电机,是现代数字程序控制系统中的主要执行元件,应用极为广泛。。在非超载的情况下,电机的转速、停止的位置只取决于脉冲信号的频率和脉冲数,而不受负载变化的影响,当步进驱动器接收到一个脉冲信号,它就驱动步进电机按设定的方向转动一个固定的角度,称为“步距角”,它的旋转是以固定的角度一步一步运行的。可以通过控制脉冲个数来控制角位移量,从而达到准确定位的目的;同时可以通过控制脉冲频率来控制电机转动的速度和加速度,从而达到调速的目的。(Stepper motor is an open loop control motor which transforms electrical pulse signal into angular displacement or linear displacement. It is the main executive element in modern digital control system, and is widely applied. In the case of non overloaded, the motor speed and stop position depends only on the pulse frequency and pulse number, regardless of load changes, when the stepper driver receives a pulse signal, it drives stepper motor to set the direction of rotation of a fixed angle, called "step", it is the rotation of the fixed point of the operation step by step. We can control the angular displacement by controlling the number of pulses, so as to achieve the goal of accurate positioning. At the same time, we can control the speed and acceleration of motor rotation by controlling the pulse frequency, so as to achieve the purpose of speed regulation.)
