用C8051F330单片机控制直流电机的程序 驱动为L298

研究所积累的资料9,大家秘密使用,千万别告诉别人!-9 Institute of accumulated data, we use a secret, please do not tell others!

优点：中断中只做很少的事情，通常我是在接收中断中post一个信号量，触发别的任务读数据-Advantages: only a small interruption in the things I usually post in the receiving a signal interruption in the amount of time to trigger other mission data

急救车与交通灯）（1）南北与东西方向，每个方面由红黄绿三个灯控制（2）南北向：　红（30秒），黄（5秒），绿（25秒）　　　东西向： 红（35秒），黄（5秒），绿（25秒）　　　上述基本参数可以根据实际情况自行调整，灯的变化规律与实际路口规律相同，绿灯在最后5秒钟时，黄灯亮，然后红灯亮，不允许两个方面同时亮绿灯。（3）绿灯的时间显示在数码管上进行显示。（4）可以通过一个开关控制，当开关信号为0时，整个交通灯全灭提高要求：（1）设计一个紧急控制开关信号，当紧急开关信号为1时，两个方向的灯全为红灯。紧急开关撤消后，按照开关按下之前的状态继续运行（其参数要保存）。（2）设计一个夜间行车开关，当开关按下后，两个方向都只有黄灯闪烁，其它灯熄灭。（3）设计两个方向的亮时时间可调。-emergency vehicles and traffic lights) (1) North and South and east-west direction, each with three yellow-green from red lights control (2) to the north and south : red (30 seconds), yellow (5 seconds), Green (25 seconds) to things : red (35 seconds), yellow (5 seconds) Green (25 seconds) above basic parameters can be adjusted to the actual situation, the light changes with the actual law of the same intersection, the green light in the final five seconds, the yellow light is on, and then a red light, bright, not two fronts simultaneously bright green. (3) the green light at the time displayed on the digital display control. (4) can be controlled by a

程序能够实现将十二位的二进制数5V对应fffH变换成一路0~5V的电压。 精度方面：在使用时上下波动范围大约是0~2fH能保证高位寄存器准确； 调试过程中遇到了一系列问题：（1）p0口的使用需接上拉电阻，内部没有带电阻；（2）调试的过程最好使用单步运行，以便于察看寄存器的内容；（3）对系统板不熟悉，一些硬件方面容易出问题，像口连接，电源、地的连接。（4）直流电源使用不准确，内部的各个电源输出是独立的，需要共地。 -procedures to achieve 12 to a binary number 5V counterparts fffH transform all the way into the 0- 5V voltage. Accuracy : the use of fluctuating ranges of 0 ~ 2fH can guarantee accurate high register; debugging process encountered a series of questions : (1) p0 I need to connect to the widening use of resistance, with no internal resistance; (2) the process of commissioning the best use of single-step operation, in order to inspect the contents of Register; (3) The right not familiar with the system board, Some hardware problems are likely to occur, such as connectors, power, and connectivity. (4) DC power supply use of inaccurate, all within the Power output is independent, to the total needs.
