Programming LCD 1602 with stm32f4

PICccs编译器包含破解方式，验证可以正常使用。(The PICccs compiler contains cracking methods to verify that it can be used properly.)

这是一段模拟电荷法（scm)的matlab源程序，求解了超高压输电线路下方工频电场，仿真出了离地面1.5m处的二维电场模型，该程序经过验证，准确无误，谢谢。(This is a charge simulation method (scm) of matlab source, solving the EHV transmission line-frequency electric field below, simulation 1.5m from the ground out of the Agency)

说明：  使用CC2530读取SHT20传感器的温湿度数据并发送或串口打印(This program get temperature and humidity data by SHT20 and send data though cc2530 with wireless or usart.)

CC2530获取终端光亮度，用于智能家居组网(Acquisition of analog brightness values in CC2530 ​ ​ for smart home networking)

基于keil软件的51单片机程序，18B20测温及12864液晶显示的文件。晶振为12M(Based on the the keil software 51 microcontroller procedure 18B20 temperature measurement and 12864 LCD file. Crystal-12M)

针对FastDFS分布式文件系统的功能测试代码(Functional test code for FastDFS distributed file system)

说明：  PWM输入+DMA，亲测可用，有需要的朋友可以自行下载。(PWM input + DMA, pro-test available.)

根据stm32f103自带DA功能和DMA实现输出正弦波,可根据改变定时器周期改变正弦波频率。(According to the DA function and DMA of stm32f103, the output sinusoidal wave can be realized, and the frequency of sinusoidal wave can be changed according to the period of timer.)
