  2. Programmable interval timer - Wikipedia

    en.wikipedia.org/wiki/Programmable_Interval_Timer

    The Intel 8253 PIT was the original timing device used on IBM PC compatibles.It used a 1.193182 MHz clock signal (one third of the color burst frequency used by NTSC, one twelfth of the system clock crystal oscillator, [1] therefore one quarter of the 4.77 MHz CPU clock) and contains three timers.

  3. Timing synchronization function - Wikipedia

    en.wikipedia.org/wiki/Timing_synchronization...

    Timing synchronization function (TSF) is specified in IEEE 802.11 wireless local area network (WLAN) standard to fulfill timing synchronization among users. A TSF keeps the timers for all stations in the same basic service set (BSS) synchronized. All stations shall maintain a local TSF timer.

  4. Time switch - Wikipedia

    en.wikipedia.org/wiki/Time_switch

    An astronomical (or astronomic) timer calculates dawn and dusk times (tracking the sun position) for each day of the year based on the latitude and longitude (or just north/central/south and time zone on more cheaply made ones), and the day of the year (month and date), programmed by the user upon installation in addition to the usual time of day, except in the case of GPS enabled astronomic ...

  6. Lighting control system - Wikipedia

    en.wikipedia.org/wiki/Lighting_control_system

    The major advantage of a lighting control system over stand-alone lighting controls or conventional manual switching is the ability to control individual lights or groups of lights from a single user interface device. This ability to control multiple light sources from a user device allows complex lighting scenes to be created.

  7. Timer - Wikipedia

    en.wikipedia.org/wiki/Timer

    A typical kitchen timer. A timer or countdown timer is a type of clock that starts from a specified time duration and stops upon reaching 00:00. An example of a simple timer is an hourglass. Commonly, a timer triggers an alarm when it ends. A timer can be implemented through hardware or software.

    an Async Type D timer that can run faster than the CPU; 12-bit ADC; 10-bit DAC; AVR DA-series (early 2020) – The high memory density makes these MCUs well suited for both wired and wireless communication-stack-intensive functions. integrated sensors for capacitative touch measurement

  9. High Precision Event Timer - Wikipedia

    en.wikipedia.org/wiki/High_Precision_Event_Timer

    The High Precision Event Timer (HPET) is a hardware timer available in modern x86-compatible personal computers. Compared to older types of timers available in the x86 architecture, HPET allows more efficient processing of highly timing-sensitive applications, such as multimedia playback and OS task switching .
