STM32读卡器，可以用stm32做一个读卡器的模块，可以让电脑读取内存卡里面的东西(STM32 memory card inside the computer reads data)

说明：  利用ti公司生产的mcu最小系统版tm4c123g可产生占空比可调的驱动波形(Driving waveform with adjustable duty cycle can be generated by using the minimum system version tm4c123g of MCU produced by TI company)

stm32控制as9854正交波形，仅供参考，自己琢磨。(stm32 control as9854 orthogonal waveforms, for reference, on her own.)

说明：  SPI STM32F051C8T6 coonfig SPI

LPC23XX主芯片用户手册，针对周立功公司ARM7开发板，文档对芯片接口进行了详细的介绍，比如CAN总线(Chip user manual, LPC23XX main, the ZLG company must see the ARM7 products, documentation, on-chip interface introduced in detail, such as the CAN bus)

近30个LPC23XX系列，各模块源代码！(Nearly 30 LPC23XX series, each module source code!)

ARM9开发裸机程序 2440之i2c操作(ARM9 development program 2440 i2c bare metal operating)

共5个文件。2个描述了一些时钟的初始化以及时钟的使用。2个描述了UART的使用。一个文件是一个简单的使用示例。(This zip file contains the simple code to control the stm32 components. It tells how to initialize the clock module, use the clock module, and how to do the same thing to UART.)

友善之臂2440（arm920T）nandflash驱动源码，c语言实现(Friendly arm 2440 (arm920T) nandflash driver source code, c language)

这个是LPC1788开发板的测试用例 都已经试过可以编译通过(This is the LPC1788 development board test cases have been compiled through)
