条码读入CPU
1. 与条码读入器的通讯
1.1 采用标准的UART通讯协议,波特率为9600,没有校验位,一个停止位。
1.2 通讯的过程是单工的,数据流总是从条码读入器到CPU。
1.3 正常的数据传送总是以一个换行符开始,六个数字,以一个回车符结束。

Microchip Technology Inc. 的HCS300 是一款跳码编码
器,它是专为安防遥控无钥门禁(RKE)系统而设计
的。 HCS300使用KEELOQ跳码技术,并具有安全性高、
封装尺寸小和成本低等特性。 HCS300 是单向遥控无钥
门禁系统和访问控制系统最完美的解决方案。-The HCS300 from Microchip Technology Inc. is a code
hopping encoder designed for secure Remote Keyless
Entry (RKE) systems. The HCS300 utilizes the KEELOQ
code hopping technology, incorporating high security, a
small package outline and low cost. The HCS300 is a
perfect solution for unidirectional remote keyless entry
systems and access control systems.via any external connection. The EEPROM data is pro-grammable but read-protected.

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.
