STC12C5410AD的SPI程序 以及AD程序 已经经过硬件调试 可用以及F410的中文版本-STC12C5410AD the SPI procedures, as well as AD after hardware testing procedures have been available, as well as the Chinese version of F410

本函数是EZ_USB的固件函数框架,实现通过端点双向通信-This function is EZ_USB firmware function framework, the realization of two-way communication through the endpoint

C8051F040的HT1380操作时序，以及时间设置和LCD时间显示(显示小时和分钟)-C8051F040 operation timing of the HT1380, as well as set-up time and time LCD display (shows hours and minutes)

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.

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

这是新华龙（www.xhl.xom.xn）开发的，基于单片机，现在可以在它的网站上免费下载，不过当初他可是花了500大元买的。 --It is developed by www.xhl.xom.xn and based on SCM.
