description/ordering information
These devices consist of two independent voltage
comparators that are designed to operate from a
single power supply over a wide range of voltages.
Operation from dual supplies also is possible as
long as the difference between the two supplies is
2 V to 36 V, and V
CC
is at least 1.5 V more positive than the input common-mode voltage. Current drain is
independent of the supply voltage. The outputs can be connected to other open-collector outputs to achieve
wired-AND relationships.
The LM193 is characterized for operation from −55°C to 125°C. The LM293 and LM293A are characterized for
operation from −25°C to 85°C. The LM393 and LM393A are characterized for operation from 0°C to 70°C. The
LM2903 is characterized for operation from −40°C to 125°C.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and

implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. All voltage values, except differential voltages, are with respect to GND.

The voltage at either input or common-mode should not be allowed to go negative by more than 0.3 V. The upper end of the common-mode voltage
range is V
CC+
− 1.5 V, but either or both inputs can go to 30 V without damage.

      资源摘要:基于STM32闭环步进电机控制系统设计（仿真，程序，说明）（1） 基本功能:本任务通过输出脉冲控制步进电机的停止、运动、方向。使用 两个按键分别控制步进电机的正转和反转，再次按下这两个按键，步进电机停止， 同时 LCD 显示电机状态信息。（2） 扩展功能:加入一个转速阈值设置功能，由电位器充当阈值设置器，可设 置目标转速并使电机接近设置的转速。

    6. STM32单片机车牌识别摄像头图像识别系统设计

      qq_63706618#硬件开发ZIP18.37MB7月前
      资源摘要:本系统有STM32F103RCT6单片机核心板、2.8寸TFT液晶屏显示、摄像头图像采集OV7670、蜂鸣器、LED电路组成。1、stm32单片机通过摄像头采集图像，并实时驱动TFT液晶屏显示相应图像。2、stm32单片机通过模式识别、匹配货的车牌的识别结果，并在屏幕上进行显示。3、识别主要过程包括图像采集、二值化分析、识别车牌区域、字符分割、字符匹配五个过程。4、车牌锁定后会有蜂鸣器提醒，在分析获取到车牌后对车停留时间进行计时，并进行计费。5、在图像采集界面，通过按键可以进入后台计费界面。在车牌识别后进入计费界面，可以通过按键退出计费界面，回到图像采集界面。注意：单片机处理能力及速率有限，目前识别汉字：渝、辽、沪、浙、苏、粤，车牌图片一定要清晰，无反光，容易识别。车牌识别操作技巧与按键功能说明：1、重要一点，通过摄像头前面螺钮可以调焦，拧到直到液晶显示图像最清晰（一般我们调试好的）。2、尽量让车牌号处于液晶中央位置，让车牌号内容处于两蓝线之间，且两蓝线处于红线上方。3、位置合适后，进入倒计时，到时蜂鸣器会“嘀
