技术资料 基于单片机的超声波测距报警系统研究
在汽车倒车时,车主可以通过终端显示器,清晰地看到汽车尾部和侧部与附近物体之间的距离,而一旦两者之间的距离小于系统预设的值时,系统就会发出警报,提示司机及时进行处理,避免出现碰撞剐蹭。可见,敏感性强、性能良好、探测范围广的测距报警系统,在日常行车中具有非常重要的应用价值。本文在简要阐述超声波测距运行机制与原理 ...
技术资料 基于单片机的便捷纸张测数装置
本纸张计数显示装置用于对70g/m2的A4纸张数进行测量。其原理是利用FDC2214模块对平行金属极板间的电容值进行测量,建立起纸张数与测量值一一对应的数学模型。装置以STM32F103C8T6单片机为控制器,对纸张数与FDC2214模块测量值按数组形式存储,作为自校准的依据。通过FDC2214模块实时测量值与数组数据的比较,在平均滤波的基础上 ...
电源技术 MR16 LED驱动MR16 LED灯与电子变压器兼容
Abstract: There are differences between the operation of low-frequency AC transformers and electronic transformersthat supply current to MR16 lamps, and there are also differences in the current draw for MR16 halogen lamps andMR16 LED lamps. These contrasts typically prevent an MR16 LED lamp from ...
单片机编程 A Single-Chip Pulsoximeter Des
This application report discusses the design of non-invasive optical plethysmographyalso called as pulsoximeter using the MSP430FG437 Microcontroller (MCU). Thepulsoximeter consists of a peripheral probe combined with the MCU displaying theoxygen saturation and pulse rate on a LCD glass. The same se ...
单片机编程 PCA9517 Level translating I2C-
The PCA9517 is a CMOS integrated circuit that provides level shifting between lowvoltage (down to 0.9 V) and higher voltage (2.7 V to 5.5 V) I2C-bus or SMBus applications.While retaining all the operating modes and features of the I2C-bus system during thelevel shifts, it also permits extension of t ...
