一个对4X4数字键盘进行行&列扫描,获取扫描码的程序,支持符合键,串键,软件去抖.-one pair of 4x4 digital keyboard ranks scanning, access code scanning procedures, with key support and collaborate keys, software to tremble.

本设计以P89V51RD2FN单片机为电动小车的控制核心，采用MSA-LD2.0倾角传感器实时测量跷跷板的倾斜角，用ST198光电传感器检测黑色引导线监测小车运动。光电传感器和倾角传感器模块把实时测量信号馈送至单片机，利用专用细分芯片TA8435H驱动步进电机，以脉宽调制式斩波方式对步进电机步进角进行细分，控制和调节小车速度。采用增量式PID控制算法确保小车能够达到平衡；用RT128×64M液晶显示时间、角度等参数。经测试表明：小车各项性能指标达到设计要求，能够实现30秒内小车行驶到规定点，并保持跷跷板平衡；在跷跷板一端配重可调整的情况下，小车也能自动找到平衡点并保持跷跷板平衡。-The single-chip design for the electric car P89V51RD2FN control of the core, the MSA-LD2.0 seesaw angle sensor real-time measurement of the tilt angle, the detection of black ST198 photoelectric sensor to monitor vehicle movement and guide lines.Photoelectric sensors and angle sensors in real-time measurement module to feed the signal to the microcontroller, using a dedicated sub-chip stepper motor driver TA8435H to PWM chopper-type stepper motor on the sub-stepping angle, control and regulation vehicle speed. The use of incremental PID control algorithm to ensure that the car can achieve balance with LCD RT128 × 64M time, angle and other parameters.After the test showed that: the performance car

本程序是通过单片机进行电机的控制，可以控制电机的转速，前进和倒退。单片机通过串口接收来计算机的控制信号(可以采用无线方式进行串口的通讯)。工具采用的是“韦福”的仿真软件。-this procedure through the MCU for motor control, control of the motor forward and retrogression. SCM through the computer serial port to receive the control signal (which can be used for wireless serial communications). Tools used the "ru" simulation software.
