高压无刷电机系统设计，包括电源，驱动，保护等重要部分(High-voltage brushless motor system design, including power supply, drive, protection and others detail)

MQ-7烟雾模块 DHT11模块 430单片机驱动 数字量 非模拟量 1602显示(MQ-7 DHT11 430F149 1602)

说明：  根据stm32f103自带DA功能和DMA实现输出正弦波,可根据改变定时器周期改变正弦波频率。(According to the DA function and DMA of stm32f103, the output sinusoidal wave can be realized, and the frequency of sinusoidal wave can be changed according to the period of timer.)

ASCII码字库，包括12*12，24*24，32*32(ASCII codeword library, including 12*12, 24*24, 32*32)

这是一个由STM32的MCU实现了脉宽调制输出的例子。(Generate PWM using STM32 MCU.)

keil4的工程文件 生日歌代码 利用蜂鸣器唱一段生日歌 能重新启停(Keil 4 Project Document Birthday Song Code Use buzzer to sing a birthday song to restart and stop)

说明：  能够驱动5v-12v直流电机电动小车的驱动不但要求电机驱动系统具有高转矩重量比、宽调速范围、 高可靠性，而且电机的转矩 -转速特性受电源功率的影响，这就要求驱动 具有尽可能宽的高效率区。(The drive of 5V-12V DC motor electric car requires not only the motor drive system with high torque-weight ratio, wide speed range and high reliability, but also the torque-speed characteristics of the motor affected by power supply power, which requires the drive to have as wide a high efficiency area as possible.)

1小时学会C语言51单片机C语言入门教程(failed to translate)

说明：  1.从键盘上输入若干两位十进制数,寻找其中的最小值,然后在屏幕上显示出来. 2.两个十进制数之间的分隔符,输入结束标志自定,但要在报告中说明. 3.对输入要有检错措施,以防止非法字符输入,并有适当的提示. 4.将整个程序分解为若干模块,分别用子程序实现.在报告中要给出模块层次图.(1 Enter a number from the keyboard two decimal digits, to find the lowest value, and then displayed on the screen.           Separator 2. Between two decimal numbers, marks the end of a custom input, but to explain in the report.           3 have error detection on the input measures to prevent the illegal character input, and have the appropriate prompt.           4. The entire program is divided into several modules, each with subroutines in the report to give the module hierarchy diagram.)

使用C8051F020驱动的DAC8541程序，其他单片机也可以参考。(DAC8541 use C8051F020-driven program can also refer to other microcontrollers.)
