单片机编程 简易频率计设计
本实验要求设计一个简易的频率计,实现对标准的方波信号进行频率测量,并把测量的结果送到8 位的数码管显示,所要求测量范围是1Hz~99999999Hz。整个设计的基本原理就是对1 秒钟之内输入的方波进行计数,把所得数据保存在计数器里,经过译码器处理之后,然后送往数码管显示。这里采用的方案是在采样时钟的上升沿开始计数,然 ...

无线通信 UHF读写器设计中的FM0解码技术
&nbsp;
&nbsp;针对UHF读写器设计中,在符合EPC Gen2标准的情况下,对标签返回的高速数据进行正确解码以达到正确读取标签的要求,提出了一种新的在ARM平台下采用边沿捕获统计定时器数判断数据的方法,并对FM0编码进行解码。与传统的使用定时器定时采样高低电平的FM0解码方法相比,该解码方法可以减少定时器定时误差累积的影 ...

C/C++语言编程 基于(英蓓特)STM32V100的看门狗程序
This example shows how to update at regulate period the WWDG counter using theEarly Wakeup interrupt (EWI).
The WWDG timeout is set to 262ms, refresh window set to 41h and the EWI isenabled. When the WWDG counter reaches 40h the EWI is generated and in the WWDGISR the counter is refreshed to prevent ...

This example provides a description of how to use a DMA channel to transfer a
word data buffer from memory (Flash) to memory (RAM).
The dedicated DMA channel is configured to transfer once a time a 32 word data buffer
stored as constant in the Flash memory to another buffer in the RAM memory.
The r ...
