LPC单片机I2C编程-LPC SCM I2C programming

控制小车用PWM方式来控制小车的转速，小车的步进电机需要用直流电机控制，因为单片机产生的电流小，需要驱动-Vehicles with PWM control mode to control the car

设计使得原本需要14个IO接口的键盘显示少用了9个单片机IO接口,虽然该设计的优势在本实验中没有完全体现出来,但若在现代工业设计中应用此方案,在对引脚需要较大的产品中其优点将体现得淋漓尽致。.-Design makes the original needs 14 IO interface shows the use of a keyboard 9 Singlechip IO interface, although the advantages of the design in this experiment did not fully reflected, but in modern industrial design in the application of this program in the pairs of primers Products feet larger in its merits and will be reflected most vividly. .

利用单片机的P32管脚进行测量频率,计时很精确-P32 pin single-chip computer to measure the frequency, timing is very precise

计数综合程序！已经调试通过，拿来就可以使用！-Comprehensive counting procedures! Have been debug is passed, use can use!

S3C44B0扩展16C554串口，包括原理图和源码 原来上传过源码，看到很多人下载，考虑到下载者阅读方便，所以这次增加了原理图。-16C554 serial S3C44B0 expansion, including schematics and source code uploaded the original source, to see a lot of people to download, taking into account that those who download the ease of reading, so the increase in schematics.

学习51的要关注哦,是STC的烧录软件,方便51单片机学习,通过串口就可一烧写程序,减少开发费用,-learning the concern Oh, STC is the replication software for 51 MCU study, through a serial port can be burning, reduce development costs,

实现stc12c5410ad/stc12c2051单片机ad转换和pwm功能-Single-chip implementation stc12c5410ad/stc12c2051 function ad conversion and pwm

基于５１单片机的３２位除法程序-based on the 32-bit microcontroller division procedures

51定时器初始值计算器(初学单片机的好工具)-51 timer starting value calculator (begins studies monolithic integrated circuit good tool)
