模拟接受max7219的数据，主要是原系统升级，需要将原单片机驱动7219的数据接受并分析数据及命令。-simulation accept the data, major upgrade of the original system, the need for the original Microprocessor 7219 data accept and analyze data and orders.

学习单片机的一本比较好的入门书，不但讲述基本的指令操作，典型应用可以作为不错的参考-learning MCU a good entry, not only about the basic operating instructions, a typical application can be used as a good reference

PICKS0108图形液晶驱动程序C源代码，编译为PICC18

PIC单片机SPI通信C语言程序（93LS46）-PIC single-chip SPI communications C Programming Language (93LS46)

改程序实现了C8051F120混合信号片上系统32位乘法，提高了在C8051上实现乘法的精度，较少了计算误差-Reform process to achieve the C8051F120 mixed-signal system-on-chip 32-bit multiplication to improve the C8051 to achieve precision multiplication, the calculation error of less

调度器内核，使用者只需要添加自己的任务即可，系统可以最多添加6个任务

用GPC和PID对汽温进行控制的代码（过程控制的作业）-GPC+PID steam temperature control

这是一个接收单片机数据的软件,通过对接收的数据分析来显示相应的LED.目前只能显示一个LED,有时间会全部做好的,目前接收到的数据为0A0B0C,也就是从单片机发出来的数据为10,11,12,单片机的程序是a-This is a single-chip microcomputer software to receive, through the analysis of data received to display the corresponding LED. Currently only display a LED, will all have time to do a good job of currently received data 0A0B0C, that is, from a single machine sent to the data for 10,11,12, SCM process is a

常用元件汇总，包括：1N系列二极管、74系列、4000与4500、变容二极管参数、常用二极管、常用芯片、场效应管性能、光电器件、横流二极管、快恢复二极管、三极管等-Summary of commonly used components, including: 1N series of diodes, 74 series, 4000 and 4500, Varactor parameters, commonly used diodes, commonly used chip FET performance, optoelectronic devices, cross-flow diodes, fast recovery diodes, transistors, etc.

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
