  2. Standard Commands for Programmable Instruments - Wikipedia

    en.wikipedia.org/wiki/Standard_Commands_for...

    The Standard Commands for Programmable Instruments (SCPI; often pronounced "skippy") defines a standard for syntax and commands to use in controlling programmable test and measurement devices, such as automatic test equipment and electronic test equipment.

  3. Ladder logic - Wikipedia

    en.wikipedia.org/wiki/Ladder_logic

    As soon as the "Run" solenoid engages, it closes the "Run" NO contact, which latches the solenoid on. The "Start" switch opening up then has no effect. Note: In this example, "Run" represents the status of a bit in the PLC, while "Motor" represents the actual output to the real-world relay that closes the motor's real-world circuit.

  4. Reset (computing) - Wikipedia

    en.wikipedia.org/wiki/Hard_reset

    For example, in the x86 architecture, asserting the RESET line halts the CPU; this is done after the system is switched on and before the power supply has asserted "power good" to indicate that it is ready to supply stable voltages at sufficient power levels. [2] Reset places less stress on the hardware than power cycling, as the power is not ...

  5. Magic SysRq key - Wikipedia

    en.wikipedia.org/wiki/Magic_SysRq_key

    Many embedded systems have no attached keyboard, but instead use a serial console for text input/output to the running system. It is possible to invoke a Magic SysRq feature over a serial console by sending a serial break signal, followed by the desired key. The method of sending a break is dependent on the terminal program or hardware used to ...

  6. In-system programming - Wikipedia

    en.wikipedia.org/wiki/In-system_programming

    Many microcontrollers need a dedicated RESET line to enter in the Programming Mode. It is necessary to pay attention to current supplied for line driving and to check for presence of watchdogs connected to the RESET line that can generate an unwanted reset and, so, to lead a programming failure. Moreover, some microcontrollers need a higher ...

  7. Pressy Button - Wikipedia

    en.wikipedia.org/wiki/Pressy_Button

    Pressy Button or Pressy is a programmable button that can be inserted into the headphone socket of a smartphone or tablet [1] and used as an extra button to perform tasks on the device. [2] It is also dubbed as the almighty Android button. [3] A Kickstarter campaign was launched in August 2013 to raise funds for Pressy. The campaign ended on ...

  8. Programmable interrupt controller - Wikipedia

    en.wikipedia.org/wiki/Programmable_interrupt...

    In computing, a programmable interrupt controller (PIC) is an integrated circuit that helps a microprocessor (or CPU) handle interrupt requests (IRQs) coming from multiple different sources (like external I/O devices) which may occur simultaneously. [1]

  9. Control system - Wikipedia

    en.wikipedia.org/wiki/Control_system

    A control system manages, commands, directs, or regulates the behavior of other devices or systems using control loops. It can range from a single home heating controller using a thermostat controlling a domestic boiler to large industrial control systems which are used for controlling processes or machines.
