一篇关于步进电机的细分，驱动，加速，减速的文章。(An article on the breakdown of stepper motors, drives, speed up, slow down the article.)

本程序是本人开发峰值电流表利用C8051F330的10位AD编写的汇编程序，里面的AD转换。CH452LED数码管驱动电路的I2C接口子程序可以参考，实际运行都已通过。(This procedure is the development of peak I use C8051F330 ammeter 10 AD to prepare the compilation process, the AD converter inside. CH452LED digital tube drive circuit I2C interface subprogram can refer to the actual operation have passed.)

根据STM32硬件开发文档绘制，原理图与PCB齐全，所使用的原理图库和PCB库也已配齐。经本人测试，完全可用，ISP系在和JLINK下载仿真都已实现。(According to the document drawn STM32 hardware development, schematics and PCB complete, the use of schematic library and PCB libraries have also been installed for. I tested, fully available, ISP tied and simulation have been achieved JLINK download.)

There is an increasing demand today for motor control circuits, as a result of the incredible proliferation of automated position control equipment, which is itself made possible by recent developments in the field of digital computation.

提高LCL型并网逆变器鲁棒性的电容电流即时反馈有源阻尼方法(Improve the LCL type grid inverter robustness of capacitive current instant feedback active damping method)

stm32的bootloader程序，基于Ymodem协议，通过Secure CRT串口实现IAP功能(stm32 the bootloader program, based on Xmodem protocol to implement IAP function via the serial port Securecrt)
