  • IrDA Standard Stack for Microchip 16-Bit MCUs
    Infrared communication is a low-cost method of providing wireless, point-to-point communication between two devices. The Infrared Data Association, often referred to as IrDA, was formed in 1994 to develop standard methods for communicating over short-range infrared transmissions. These standards
  • Implementing a Simple Serial Mouse Controller
    interfaces to the host via a dedicated interface card or an RS-232 port. Their mechanisms are very similar. The major electrical components of a mouse are: ? Microcontroller ? Photo-transistors ? Infrared emitting diode ? Voltage conversion circuit The intelligence of the mouse is provided
  • Medical Device Link .
    in mW or dBm. Wavelength can be measured from 500 to 900 nm with an approximately 2-nm tolerance. Offering an easy-to-read digital display, the handheld device is designed to be user-friendly. Data can be transmitted from the system using an RS-232 interface. The instrument is available from the company
  • Sensor Sense: Optical data transmission
    are called couplers. They use pulse-modulated infrared light to transfer digital signals. The use of light as the transfer method means that ODTs do not incur physical wear like drag cables and slip rings nor require recalibration like radio systems. They operate without problems in electrically noisy
