- 动态扫描显示接口 动态扫描显示接口是单片机中应用最为广泛的一种显示方式之一。其接口电路是把所有显示器的8个笔划段a-h同名端连在一起，而每一个显示器的公共极COM是各自独立地受I/O线控制。CPU向字段输出口送出字形码时，所有显示器接收到相同的字形码，但究竟是那个显示器亮，则取决于COM端，而这一端是由I/O控制的，所以我们就可以自行决定何时显示哪一位了。而所谓动态扫描就是指我们采用分时的方法，轮流控制各个显示器的COM端，使各个显示器轮流点亮。-dynamic scan displa

- 时序电路是指它的输出不仅取决于当时的输入，而且也取决于过去的输入，即过去输入不同，则在当前的情况下，输出也可能不同。-Sequential circuit is the output depends not only on its input at that time, but also on past input, that is different from the last input, then in the current circumstances, the output also
Bootloader
- 基于AT91RM9200的BootLoader设计与实现 ，依赖于CPU体系结构的代码，比如设备初始化、开关中断、初始化时钟等，通常都放在stage 1中，而且都用汇编来实现，以达到短小精悍的目的。而stage 2通常用C语言来实现，这样可以实现较复杂的功能，而且代码有较好的可读性和可移植性。-AT91RM9200-based design and implementation of the BootLoader, depends on the CPU architecture of the c

- 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元件。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，即给电机加一个脉冲信号，电机则转过一个步距角。-Stepper motor is the electrical impulse signals into angular displacement or linear displacement of the open-loop control components. In the non-overl
