我收集的fft算法-I collected fft Algorithm

详细的红外测温模块的电路原理图，以及驱动程序源代码。-Infrared temperature measurement module detailed schematic diagram of the circuit, as well as the driver source code.

这个是STM32 MODBUS程序 经过测试可以用，串口加定时器中断实现数据传输。3.5个字符时间收不到数据即认为是一帧数据发送结束。

应用背景 调试通过的u盘程序，主芯片stm32f103，实现了fatfs文件系统。。。。。。。。。。。。。。。。。。关键技术在open103v（STM32F103V芯片）开发板上做的NANDFLASH做U盘程序，刚刚调试通过，不过速度还有点慢。

单片机复位电路的可靠性设计复位电路的基本功能是 系统上电时提供复位信号直至系统电源稳定后撤销复位信号为可靠起 见电源稳定后还要经一定的延时才撤销复位信号以防电源开关或电源插头分-合过程中引起的抖动而影 响复位-MCU reset circuit reliability design of the circuit" s basic function is to reset the system power-on reset signal until the system is to provide stable power to withdraw the sake of the reset signal as a reliable power supply stable even after a certain delay to revoke a reset signal to prevent the power switch or Power plug points- combined jitter caused in the course affected by reset

用em4094和STC12C5412合成二代证读写器，该文中有完全原理图和软件设计思路 -Synthesis of second generation with the em4094 and STC12C5412 card reader, the text has full schematics and software design ideas

pcmic初始代码！--Startup code for pcmic.

嵌入系统 基于s5p210裸机程序 仅供参考和学习 控制LED的开发环境是在linux操作系统中。测试通过 运行正常

用TC2实现的DOS多任务功能，包含全部源代码。-using the DOS TC2 achieve multi-tasking functionality, including full source code.
