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.)

tms320F28335是一款新的dsp芯片，svpwm算法的实现和以前的2812等有点不同，现在将我写的分享给大家，已经调试过了，晶振是20MHz。28335的svpwm的实现。(tms320F28335 is a new dsp chip, svpwm algorithm implementation and the previous 2812 and so a little bit different, now I write for everyone to share, debugging, and the crystal is 20MHz. 28335 svpwm implementation.)

MPU6050传感器6050程序代码，基于430f5529单片机实现(MPU6050 sensor 6050 program code, based on 430 microcontroller is f5529)

MSPf5529LCD1602显示，初学小实验。(MSPf5529LCD1602 shows that the primary school experiment.)

待检测pcb板和标准pcb对比，然后对待测pcb腐蚀及膨胀处理，进行缺陷标注显示图像并输出焊盘缺失数，导线缺失数，短路数等。所以源图像均有，并再次测试无误，可以直接运行。(To be detected and the standard pcb board pcb contrast, then treat corrosion test pcb and the expansion process, defect labeling displays images and outputs missing number pad, missing a few wires, short circuit and number. So were the source image, and test again correctly, you can run directly.)

存储器（RAM 6264）扩展 可编程并行接口（8255）扩展 可编程计数/定时器（8253）扩展 A/D、D/A转换 可编程串行通信接口（8251）扩展 　　(Memory (RAM 6264) extended programmable parallel interface (8255) extended the programmable counter/timer (8253) Expansion A/D, D/A conversion programmable serial communication interface (8251) extended)

利用被动传感器坐标位置及测角误差 计算两站及多站无源测向交叉定位的精度矩阵 (The use of passive sensor coordinate position and angle measurement error calculation two stations and multi-station Passive Direction Finding Cross positioning accuracy matrix )

基于正点原子STM32F407的LCD显示实验(LCD Display Based on Positive Atom STM32F407 Explorer Platform)

实现STM32单片机使用RDA5807M型号的芯片收音机，代码通过简单的移植，就可以使用。(Implement STM32 MCU chip radio RDA5807M model code by simply transplant, it can be used.)
