用KEIL开发的操作C51单片机的IO口，使得完成对IO口的读写等操作...

用51写的接收GPS数据的程序，采用中断查寻来接受数据。本程序只接收纬度，经度，时间，.....接收其它数据类似-write with 51 receiving GPS data procedures used to receive interrupted tracing data. This procedure will only receive latitude, longitude, time ...... receiving other similar data

very good c program for software

浮点除法子程序,可以高效率计算浮点浮点除法,程序短小精干,非常讨巧-floating-point division subroutine, high efficiency calculation float float division, procedures small and lean, very quick and easy

利用DS18B20采集温度，显示温度到lcd上-DS18B20 collected using temperature, shows that the temperature on the lcd

在winavr上调试的一个adc程序，可测试。-In a winavr debugging adc procedures, can be tested.

波轮式全自动洗衣机的单片机控制.很实用的--Using SCM to control an automatic laundary machine.

单片机控制122x32液晶。液晶内部芯片包含RAM（类似于显存），当然不具备2D3D加速。不过，功耗非常低，一般几个毫瓦。-SCM 122x32 LCD. LCD chip contains an internal RAM (similar to memory), of course, does not have to speed up 2D3D. However, power consumption is very low, generally a few milliwatts.

用AD603提高超声波测距范围。超声波测距是一种非接触的测量方式，它是根据超声波从发射传感器到反射物体，再从反射物体到接收传感器的延迟时间.，利用距离/01. 2 ’，得到距离值，1 为声波在空气介质中的传播速度。由于反射超声波接收时的信号幅度与反射物体离接收传感器的距离远近有关，一般相差几十分贝-Ultrasonic Distance Measurement with the scope of AD603 improve. Ultrasonic Distance Measurement is a non-contact measurement, which is the ultrasonic sensor to the reflection from the launch of objects, objects from the reflector to the receiving sensor delay time., The use of distance/01.2, the distance values, one for the sound waves in air medium velocity. Receive as a result of reflection at the time of ultrasonic signal amplitude and the reflection from the object to receive the sensor distance, generally a difference of tens of decibels
