stm32用作频率测试的程序
基于stm32 的单片机频率检测,精度可达到0.00,上限未知,频率:单位时间内完成振动的次数,是描述振动物体往复运动频繁程度的量,常用符号f或v表示,单位为秒-1。为了纪念德国物理学家赫兹的贡献,人们把频率的单位命名为赫兹,简称“赫”。每个物体都有由它本身性质决定的与振幅无关的频率,叫做固有频率。频率概念不仅在力学、声学中应用,在电磁学和无线电技术中也常用。交变电流在单位时间内完成周期性变化的次数,叫做电流的频率。
分析:把一件事情、一种现象、一个概念分成较简单的组成部分,找出这些部分的本质属性和彼此之间的关系。分析的意义在于细致的寻找能够解决问题的主线,并以此解决问题。分析方法作为一种科学方法由笛卡尔引入,源于希腊词“分散”。分析方法认为任何一个研究对象都是由不同的部份组成的,是一种机制。

stm32红外遥控
应用背景红外遥控的编码目前 红外遥控的编码目前 红外遥控的编码目前 红外遥控的编码目前 广泛使用的是: 广泛使用的是: 广泛使用的是: NEC Protocol 的PWM(脉冲宽度调制)和Philips
RC-5 Protocol 的PPM(脉冲位置调制)。ALIENTEK战舰STM32开发板配套的遥控器使用的是NEC协议,其特征如下:
1、8位地址和8位指令长度;
2、地址和命令2次传输(确保可靠性)
3、PWM脉冲位置调制,以发射红外载波的占空比代表“0”和“1”;
4、载波频率为38Khz;
5、位时间为1.125ms或2.25ms;关键技术本实验采用定时器的输入捕获功能现红外解码, :开机在LCD上显示一些信息之后,即进入等待红外触发,如过接收到正确的红外信号,则解码,并在LCD上显示键值和所代表的意义,以及按键次数等信息。同样我们也是用LED0来指示程序正在运行。

LPC2148 USB音频设备的例子
LPC2148 USB Audio Device Example
This USB example project implements an USB Audio Device that connects via the USB interface to the PC. It may be used on the following devices:
LPC2141
LPC2142
LPC2144
LPC2146
LPC2148
An USB Audio Device (HID) does not require any special USB driver, since the USB Audio support is already built into Windows 2000 and Windows XP. Therefore USB Audio devices can be directly connected to the computer. This example project is designed to work with Keil MCB2140 Evaluation Board.
Refer to Running USBAudio for information on how to operate this example project.-LPC2148 USB Audio Device Example This USB example project implements an USB Audio Device that connects via the USB interface to the PC.
