data_transfer

As a multicarrier transmission system Orthogonal frequency division multiplexing (OFDM) has been widely applied in wireless communication systems due to its numerous advantages like robustness against multipath fading and delay, high data rate transmission capability, high spectral efficiency, allows adaptive modulations

说明：  12864液晶显示，采串并形都有 for msp430 x芯片驱动代码 画图都有十分方便使用 。 12864LCD属于点阵图形液晶显示模块，不但能显示字符，还能显示汉字和图形，分带汉字库和不带那字库两种，价格也有差别。(12864 LCD belongs to dot matrix graphics LCD display module. It can display not only characters, but also Chinese characters and graphics. There are two kinds of Chinese character library and non-Chinese character library, and the price is also different. The 12864LCD with Chinese character library is very convenient to use. It does not need to write complex Chinese character display program. As long as two bytes of Chinese character machine code are written in time sequence, Chinese characters can be displayed. The driver is much simpler.)

门禁开发流程，通用流程解析，详细分析了小区门禁开发流程和思路等(Access control development process, general process analysis, train of thought analysis, etc.)

这个是C++编程实例100篇，里面包含有100个工程实例用于学习(C++ Programming Example 100)

STM32F407通过ADC，DMA输出 幅值，频率可调正弦波(STM32F407 outputs amplitude and frequency adjustable sinusoidal wave through ADC and DMA)

说明：  可以用于开发微星公司旗下dspic2010单片机程序，windows操作系统可以安装(Can be used to develop MSI company's dsPIC2010 MCU program, windows operating system can be installed)

基于51单片机的按键例程，常见问题： 1. 按键无反应 请您确认程序是否下载成功，连线正确无误，确认无误后还是无效果的话，将排线重新插拔下，单片机拿下来重新安装，重启开发板试试！(Key routines based on 51 single chip microcomputer,common problems: 1. Press the key and no response. Please confirm whether the program was downloaded successfully and the connection is correct. If it is still ineffective after confirmation, plug and unplug the cable again, take down the MCU and reinstall it. Restart the development board to try!)

This is the source code of the driver of the two wire serial comunication (i2c) for PIC4 microcontroller.
