  • ForDummies_RFID_For_Dummies

    With all the recent hype over radio frequency identification (RFID) and the requirements to implement it, you might think that RFID can turn water into wine, transform lead into gold, and cure the world’s diseases. You might also be worried that RFID will enable Big Brother to track your move- ments to within a foot of your location from a satellite five hundred miles up in space. The truth is, RFID can do NoNE of these things. In this chapter, you find out the basics of what RFID is, what forces are dri- ving RFID as a replacement for the bar code in the marketplace, and what benefits RFID can offer

  • DAC8568驅動程序

    This example shows how you can use signal functions in the Visiondebugger to simulate a signal that is coming into one of the analog inputs of the LPC21xx.The Measure example is described in detail in the Getting StartedUser's Guide.The MEASURE  example program is available for several targets:Simulator: uVision Simulator for LPC2129MCB2100:   Keil MCB2100 evaluation board with ULINK debugger           - Application is loaded to internal Flash.           - Switch S2 (INT1) is used as GPIO and sampled             (jumper positions: J1= off, J7= on)           - potentiometer POT1 is sampled as AIN0             (jumper position: J2= on)           - serial port COM1 parameters: 9600 baud, no parity,             8-bits, 1 stop bit, flow control NoNEMCB2130:   Keil MCB2130 evaluation board with ULINK debugger           - Application is loaded to internal Flash.           - Switch S2 (INT1) is used as GPIO and sampled             (jumper positions: J1= off, J7= on)           - potentiometer POT1 is sampled as AIN1             (jumper position: J2= on)           - serial port COM1 parameters: 9600 baud, no parity,             8-bits, 1 stop bit, flow control NoNE

  • MAX30100血氧、心率檢測

       基于美信血氧和<a href="https://www.cirmall.com/circuits/tags/3004" "="" style="box-sizing: border-box; background: 0px 0px; color: rgb(5, 163, 94); text-decoration-line: NoNE;">心率檢測,以單片機STM32F103CBT6為主控核心,其中涉及電源模塊、心率血氧模塊、藍牙模塊。電源模塊是提供所有系統的供電,心率血氧是整個系統功能的實現,MCU讀取心率血氧信號,分析數據,藍牙模塊是實現無線的一種方式,連接外部和單片機。本設計可以通過手機藍牙連接。測量者可將手指放于被測處,測得的數據可在單片機上直觀顯示或者是電腦顯示。在數據顯示的問題上,本設計采用了二種方法,一種是手機藍牙連接,利用手機藍牙連接硬件電路的藍牙模塊,通過藍牙傳輸數據送往手機顯示,第二種是單片機液晶屏顯示,被測者可在液晶屏上直接獲取自己的血氧脈搏的數據。 最終,被測者可獲得自己的心率和血氧值。
