多层pcb板，可以直接制版并输出。本板是六层pcb，由dsp+arm共同组成！(Multilayer pcb boards, and can output to plate. The board is six pcb, composed of the dsp+ arm!)

stm32 smbus驱动程序，smbus和ii2c差不多，但有很多不同(stm32 smbus driver, smbus and ii2c similar, but there are a lot of different)

dspic33系列单片机，直流无刷电机控制程序，程序有注释，已调试修改(dspic33 series microcontroller, brushless DC motor control procedures, program notes, have been debug modification)

说明：  针对MCS-51单片机的硬件结构和原理、指令系统、汇编、中断、定时器、并行扩展等进行了讲解。(The hardware structure and principle, instruction system, assembly, interrupt, timer and parallel expansion of MCS-51 single chip computer are explained.)

基于430的DC_DC变化，采用PID控制，调节PWM的输出占公比，从而反馈调节输出电压(Based on 430 DC_DC change, using PID control, adjust the PWM output accounted common ratio, thus regulating the output voltage feedback)

This class checks whether the output is up to date.

说明：  机械臂控制，基于keil的程序，lcd屏控制(Manipulator control, keil-based program)

Written between C# and SIEMENS PLC1200, through the socket communications

基于NXP LPC2478的uCGUI例程，实现LCD和SDRAM的测试(uCGUI based on NXP LPC2478，include LCD and SDRAM test)

说明：  中移物联M5310A的基于C的软件代码，对学习NB-IOT的使用有较大帮助(The C-based software code of China Mobile IOT m5310a is helpful for learning the use of nb-iot)
