mcu msp430F149中看门狗WDT的应用(mcu msp430F149 application of the WDT in watchdog)

本节所给出主程序功能为51单片机从USB总线读取两个字节数据，计算两个数据的和。另外本文还给出了CH372的主端点、辅助端点之间数据上传下传的子程序，供读者参考。(The main function of this section is given as 51 microcontroller reads the two bytes of data the USB bus, two data and computing. This article also gives additional primary endpoint between the auxiliary endpoints CH372 Uploaded data transfer routines, for reference)

cj60lib示例代码，包含例子的工程，虽然简单却实用。(example of cj60lib)

基于msp430单片机的秒表及12864函数，经过149及169验证的(Msp430 microcontroller based function stopwatch and 12864, after 149 and 169 validation)

一个变压器保护的程序，是配电变电所内的保护程序(A transformer protection program, is within the power distribution substation protection program)

模拟BMS，测试充电桩，经测试完好！符合《GB-T 27930-2015 电动汽车非车载传导式充电机与电池管理系统之间的通信协议》，用的USB转CAN外接模块。(Analog BMS, charging pile test, tested good! In line with the communication protocol between the GB-T 27930-2015-board electric vehicle conductive charging unit and battery management system. )

基于STM32F4的四轴航拍平台。以STM32F407为控制核心，四轴飞行器为载体，辅以云台的航拍系统。硬件上由飞控电路，电源管理，通信模块，动力系统，机架，云台伺服系统组成。算法上采用简洁稳定的四元数加互补滤波作为姿态解算算法，PID作为控制器，实现飞行，云台增稳等功能(Four axis aerial platform based on STM32F4. Taking STM32F407 as the control core, the four axis flying vehicle as the carrier, and the aerial camera system with ptz. The hardware is composed of flight control circuit, power management module, communication module, power system, frame and PTZ servo system. The algorithm uses a simple and stable four yuan number plus complementary filtering as the attitude calculation algorithm, and PID is used as a controller to achieve flight, PTZ stability, and other functions)

本总体方案完成国标GB20600-2006数字电视地面广播传输系统基带部分功能。 输入数据码流经过扰码器（随机化）、前向纠错编码（FEC），然后进行比特流到符号流的星座映射，再进行交织后形成基本数据块，基本数据块与系统信息组合（复用）后并经过帧体数据处理形成帧体，帧体与相应的帧头（PN序列）复接为信号帧（组帧），经过基带后处理转换为输出信号（8MHz带宽内）。该信号经变频转换为射频信号（UHF和VHF频段范围内）。用C程序设计了图形交互界面，可以在界面上直接设置调制参数。(The overall program completion GB GB20600-2006 digital terrestrial television broadcasting transmission systems baseband function. The input data stream through the scrambler (randomization), forward error correction (the FEC), then the symbol constellation mapping bitstream to the stream, and then after forming the basic block interleaving, the basic data block and information combined system ( multiplexing) after data processing and after the frame body forms a frame body, frame body with a corresponding header (PN sequence) multiplexed signal frame (framing), after post-processing baseband signal is converted to an output (internal 8MHz bandwidth). The signal is downconverted to a radio frequency signal (in the VHF and UHF frequency range). C program designed graphical interface, you can set modulation parameters directly on the screen.)
