自定义数字键盘，IOS编程学习源码，很好的参考资料。(Custom digital keyboard, learning IOS programming source code, a good reference.)

此为基于单片机的可视听诊器设计。利用C语言实现了驻极体式声音传感器实现的心音数据采集系统功能，利用图形液晶模块实现显示的新型可视电子听诊器功能。(This is based on single-chip design visual stethoscope. The use of C language realization of the electret-type sound of the heart sound sensor data acquisition system, using graphic LCD display module to achieve a new type of visual function electronic stethoscope.)

Profibus-DP从站原理图， VPC3芯片配合STM32F103RBT6的系统，AD6原理图格式。(Profibus-DP slave schematics, VPC3 chip with STM32F103RBT6 system, AD6 schematic format.)

船舶螺旋桨设计程序，简单实用，不再需要人工查询图谱，B桨，au桨设计都有(ship propeller design )

该程序为数码管静态显示程序。 每按一次 独立按键 中的 T0，数码管的值便会加一(The procedure for the digital static display program. Each time you press the button in the Independent, the value of the digital tube will add a T0)

说明：  AD7175-2 24位ADC采集 stm32f103(Ad7175-2 24 bit ADC acquisition stm32f103)

说明：  本实验将实现如下功能：本章我们在UCOSII里面创建3个任务：开始任务、LED0任务和LED1任务，开始任务用于创建其他（LED0和LED1）任务，之后挂起；LED0任务用于控制DS0的亮灭，DS0每秒钟亮80ms；LED1任务用于控制DS1的亮灭，DS1亮300ms，灭300ms，依次循环。(This experiment will achieve the following functions: in UCOSII, we create three tasks: start task, LED 0 task and LED 1 task, start task for creating other tasks (LED 0 and LED 1), then hang up; LED 0 task for controlling the brightness of DS0, DS0 80 ms per second; LED 1 task for controlling the brightness of DS1, DS1 300 ms. 300 ms, cycle in turn.)

说明：  430单片机中的led显示模块,对于初学者来说,这个程序简单易懂,是学习430的好帮手(430 in single-chip led display module, for beginners, this easy-to-read program is a good helper to learn 430)

典型PID算法程序，经实验，控制效果优，控制精度高。(It is a representative program of PID arithmetic.The effect of control is excellent and the precision of control is high via experiment.)
