凌阳最出的超声波测距模组，通过555产生40KHz的超声波，有SPE061A单片机控制超声波的发射和接收，最初的版本在程序方面比第二版本来得简单，主要是通过了硬件电路减少了程序，附电路图、PCB图等-Sunplus most of the ultrasonic ranging modules, 40KHz generated through 555 of the ultrasound, ultrasound has SPE061A single-chip microcomputer to control the transmitting and receiving an initial version of the procedure than the second version is more simple, mainly through the reduction of hardware circuit procedures, with schematics, PCB map

脉冲发生测试.此程序为AD9850（DDS）直接数字频率合成器C语言源码。用125M的有源晶振，频率无失真输出可达到40M。-Impulse test. This procedure for the AD9850 (DDS) Direct Digital Frequency Synthesizer C language source code. With 125M active crystal, the frequency output can be achieved without distortion 40M.

这个是我今天用Keil_C51写的关于MAX5417的底层函数，微控制器可以用其他的（我是用51的，其他的话，只要修改一下头文件就可以了），上层软件只要调用Write_MAX5417()这个函数就可以了，代码简洁，层次分明，注释也不少，非常适合新手学习或者是直接拿来为自己的上层软件服务。-This is what I write today with Keil_C51 on the bottom of MAX5417 function, microcontroller can use the other (I am using the 51 other words, as long as the modified header file you can), and the upper software as long as the call Write_MAX5417 () this function it, the code is simple and structured notes are also many, very suitable for novices to learn, or is directly used for their top software services.
