SPI

stm32下跑通usb外设，编译环境基于keil(stm32 next run through usb peripherals, based on keil compiler environment)

keil c51 V7.50 完整版 ，并带破解版、但在中文环境有BUG，无2K限制，已经注册可以至2033年(Keil full version and bring change, but in the Chinese environment BUG, 2K without restrictions, to be registered in 2033)

USefull memory chip to use with embedded micro controllers. The Chip interfaces on the SPI bus and provides a method of high capacity non-volatile memory storage

采用8位MCU的燃气点火器的源程序，采用汇编程序编写(8-bit MCU gas ignition source, using assembler programming)

基于stm32单闭环pid调速控制，单电阻采样，正弦波驱动，pid调速。(Based on stm32 pmsm drive, single sampling resistor, sine wave drive, pid speed control.)

基于stm32固件库的跑马灯范例，供参考(An Example of Racing Horse Lamp Based on STM32 Firmware Library)

The paper deals with the process of designing a phonetically and prosodically rich speech corpus for unit selection speech synthesis. The attention is given mainly to the recording and verification stage of the process.

说明：  利用DHT11采集温湿度，利用中断，每2秒采集一次，并利用串口传输至上位机系统(use DHT11 to get temperature and humidity)

说明：  飞思卡尔智能车控制代码，我们做的是变形三轮直立组，目前只有三轮状态下的运动控制代码，PID参数需要结合自己车模的结构参数做相应的调整，速度环和方向环均采用的是位置式pid算法。(Freescale Intelligent Vehicle Control Code, we do deformation three-wheel vertical group, currently only three-wheel motion control code, PID parameters need to be adjusted with the structural parameters of their own model, speed loop and direction loop are using position PID algorithm.)
