UART
同时使用STM32三个串口的接收与发送，串口1使用printf(),串口2使用u2_printf(),串口3使用u3_printf().接受采用定时器中断超时，5ms未接收到数据认为本次接收结束，置位相应的标志位，主程序检测并处理接收数据。(STM32 simultaneously receive and send three serial, serial port 1 to use printf (), 2 serial ports use u2_printf (), 3 serial ports use u3_printf (). Accepting timer interruption timeout, 5ms does not receive data that the receiving end of this, set the appropriate flag, the main program to detect and process the received data.)

ANOlog_TMS320F28335
本装置采用单相桥式DC-AC逆变电路结构，以TI公司的浮点数字信号控制器TMS320F28335 DSP为控制电路核心，采用规则采样法和DSP片内ePWM模块功能实现SPWM波。最大功率点跟踪（MPPT）采用了恒压跟踪法（CVT法）来实现，并用软件锁相环进行系统的同频、同相控制，控制灵活简单。采用DSP片内12位A/D对各模拟信号进行采集检测，简化了系统设计和成本。本装置具有良好的数字显示功能，采用CPLD自行设计驱动的4.3’’彩色液晶TFT LCD非常直观地完成了输出信号波形、频谱特性的在线实时显示，以及输入电压、电流、功率，输出电压、电流、功率，效率，频率，相位差，失真度参数的正确显示。本装置具有开机自检、输入电压欠压及输出过流保护，在过流、欠压故障排除后能自动恢复。(This device single-phase bridge type DC-AC inverter circuit structure, TI company of floating in digital signal controller TMS320F28335 DSP as the control circuit, the core rules sampling method and DSP piece ePWM module function realization within SPWM wave. The maximum power point tracking (MPPT) used the constant pressure tracking method (CVT method) to realize the software, and phase lock loop to carry on the system the same frequency, phase control, control with flexible simple. By using DSP piece of 12 within the A/D of each simulation signal acquisition detection, simplified system design and cost. This device has a good digital display function, use CPLD to design the driver 4.3 " TFT LCD color LCD very intuitive to finish the output signal waveform and spectrum characteristics of online real-time display, and the input voltage, current, power, the output voltage, current, power, efficiency, frequency, phase difference, the distortion degree of parameters display properly.

STC8_Delay
说明： 次代码是针对STC8系列的单片机的延时函数，使用
此代码可以直接添加调用，程序自动获取内部系统时
钟后初始化延时函数。只要是ISP软件默认的时钟频
率都可以应用（特殊频率除外）
该代码为初版，还存在很多缺陷，请各位大佬勿喷，谢谢！
注意：
次代码仅适用于STC公司最新的STC8系列单片机(Delay Function of Single Chip Microcomputer)
