CC2591功放PCB CC2530+PA (CC2591 power amplifier PCB CC2530+ PA)

这是24L01开发头程序，希望对大家有帮阻(24L01 This is the first development process, we hope to help a resistance)

设计并制作一个功率可程控的高效率音频功率放大器及其参数的测量、显示装置。功率放大器的电源电压为+12V（电路其他部分的电源电压不限），负载为8Ω电阻。(Audio amplifier)

双步进电机综合控制 用于51单片机 (Dual stepper motor integrated control)

基于STM32的双串口通信程序，能实现两个串口的收发，程序默认采用串口2接收数据，串口1发送(Based on the STM32 dual serial communication procedures, can achieve two serial transceivers, the program defaults to the serial port 2 receives the data, send the serial port 1)

笔记本键盘测试程序，可以测试键盘按键是否有作用。(Notebook keyboard test program.)

LTM公司芯片的时钟配置资料。内容很详细清楚！(LTM chips clock configuration data. Content is more clear!)

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.)
