数字频率合成器DDS9851的驱动程序实验

利用pic单片机的定时计数器测量汽车轮速，并利用串口将数据发送出去。-Using pic microcontroller timing counter measure vehicle wheel speed, and the use of serial data sent.

这是我用汇编语言编写的计时器程序，通过计算机发命令开始倒计时，其中也有其他功能，但主要是倒计时，比较好用，这是个小程序，穿上来了表心意-This is the language I used compilation prepared by the timer procedures, through the computer started the countdown orders, which also has other functions, but the countdown is more convenient, it is a small program to put on the table liking

这个是在参加电子设计大赛时的作品，里面包含了数控稳压电源的设计原理、细节、源码-is participating in the Electronic Design Competition at work, it contains the NC Regulators Power design principle, details OSS, etc.

通讯规则: 1:时钟7.3728 MHz/波特率9600/9个数据位/奇校验/1个停止位/硬件多机通讯功能/ 2:通讯连接采用硬件MAX485,双向单工 3:每个上行/下行的数据包的字节个数都是一样的(通讯数据量) 4:每个上行/下行的数据包都采用CRC8校验 5:数据接收采用中断+查询的方式 6:总是由主机向从机发送一个数据包,从机收到数据包后向主机回复一个数据包 7:不管是主机还是从机,如果收到的数据包有任何错误,都将丢弃该数据包,等效于没有接收 8:从机之间不能相互通讯,必须通过主机才能交换数据 9:无效地址是0,主机地址是1,从机地址是2.3.4......广播地址是255 -err

视觉暂留，编程从一个I/O口输出一扫频信号，驱动一支LED灯闪动，频率范围为10HZ~99HZ，扫描时间为30秒，在LED闪动期间观察，一旦发现无法识别LED灯闪动时，按下按键K1，立即停止输出，并将此时的信号频率显示在数码管上，该信号的周期为测试者的视觉暂留时间。-Persistence of vision, programming from an I/O port outputs a sweep signal to drive an LED light flashing, the frequency range of 10HZ ~ 99HZ, scan time of 30 seconds, the LED flashing during the observation, once found it impossible to identify the LED lights flashing, press the key K1, immediate cessation of the output, and at this time the signal frequency displayed on the digital control on the test cycle of the signal" s persistence of vision time.
