采用磁共振方式的无线充电专利文件，分享给对无线充电技术感兴趣的朋友 wireless Power(Using magnetic resonance wireless charging patent file sharing to friends interested in wireless charging technology)

自己写的，TI的TMS320F28335程序，使用AD7606，DA7724，LCD 12864模块显示，调试可用(Write MY own, TMS320F28335 TI program, using AD7606, DA7724, LCD 12864 module display, debugging available)

这是一个基于C51的软件模拟串口程序，希望对大家有用。(This is a C51-based simulation software serial procedures in the hope that useful.)

可以产生幅度、频率可调的方波，频率50hz到1M(Can produce the amplitude, frequency adjustable Fang Bo, frequency of 50Hz to 1M)

STM32F407 MPR121键盘模块驱动，可以实现12个触摸点并且读出键值(STM32F407 MPR121 driver)

说明：  基于MSP430F5438A的AD9854驱动，AD9854的DDS核具有48位的频率分辨率（在300M系统时钟下，频率分辨率可达1uHZ）。输出17位相位截断保证了良好的无杂散动态范围指标。AD9854允许输出的信号频率高达150MHZ(Based on the AD9854 driver of MSP430F5438A, the DDS core of AD9854 has a frequency resolution of 48 bits (up to uHZ at 300 M system clock). Output 17-bit phase truncation ensures a good dynamic range index without spurious. AD9854 permits up to 150 MHZ of output signal frequency)

说明：  Si417发射机的PCB文件以及数据手册、arduino控制si4713的代码文件。(The PCB file of Si417 transmitter and the code file of data manual and Arduino controlling si4713.)

可驱动8/16位数码管显示或64/128只独立LED 的芯片BC72811A中断编程。BC7281A只占用单片机3个I/O口(can drive 8/16 Digital Display or 64/128 only independent LED chip BC72811A interrupted programming. BC7281A only occupies three microcontroller I/O port)

使用STM32F103 32位芯片配置红外遥控器以及控制红外遥控器(Configuration of Infrared Remote Controller and Control of Infrared Remote Controller with STM32F103 32 Bit Chip)
