18B20在msp430下的应用 没有错误，运行相当完好 且兼备简洁易用的优点-18B20 in MSP430 applications under the error-free, running very well and the advantages of both simple and easy-to-use

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
