基于STC89C52单片机实现中断LED数码管显示及处理的程序，适合初学值使用(Based STC89C52 MCU interrupt LED digital display and processing procedures, suitable for beginners to use the value)

PROFIBUS-DP现场总线智能节点的设计程序和源码电路图(Design of intelligent node based on PROFIBUS-DP)

使用单片机任意IO口用软件的方法模拟实现异步串行数据传输的方法，并采用多次采样软件方法来增加软件模拟串口通讯的可靠性，在以上基础上，进一步用具有中断功能的IO口来实现数据的接收，从而增加软件模拟方式的实用性和灵活性；(The use of single-chip arbitrary IO port with the method of software simulation method to realize asynchronous serial data transmission, and the reliability of software sampling method to increase the software simulation of serial communication, on the basis of the above, further with interrupt function of IO port to realize the data receiving, thereby increasing the practicability and flexibility of software simulation method;)

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.)

说明：  stm32 无线收发，基于nrf24l01(STM32 wireless transceiver, based on nRF24L01)
