  2. Digital timing diagram - Wikipedia

    en.wikipedia.org/wiki/Digital_timing_diagram

    The timing diagram example on the right describes the Serial Peripheral Interface (SPI) Bus. Most SPI master nodes can set the clock polarity (CPOL) and clock phase (CPHA) with respect to the data. This timing diagram shows the clock for both values of CPOL and the values for the two data lines (MISO & MOSI) for each value of CPHA.

    A signal represented as a time series of samples taken at regular intervals. displacement current The effect of a time-varying electric field, which induces a magnetic field just as the motion of electrical charges does. display device Any device that displays data from an information system, such as a watch readout or an automatic scoreboard.

    Arduino (/ ɑː r ˈ d w iː n oʊ /) is an Italian open-source hardware and software company, project, and user community that designs and manufactures single-board microcontrollers and microcontroller kits for building digital devices.

  6. Unit interval (data transmission) - Wikipedia

    en.wikipedia.org/wiki/Unit_interval_(data...

    When UI is used as a measurement unit of a time interval, the resulting measure of such time interval is dimensionless. It expresses the time interval in terms of UI. Very often, but not always, the UI coincides with the bit time, i.e. with the time interval taken to transmit one bit (binary information digit).

  7. Asynchronous serial communication - Wikipedia

    en.wikipedia.org/wiki/Asynchronous_serial...

    Asynchronous serial communication is a form of serial communication in which the communicating endpoints' interfaces are not continuously synchronized by a common clock signal. Instead of a common synchronization signal, the data stream contains synchronization information in form of start and stop signals, before and after each unit of ...

    Block diagram for a UART. A universal asynchronous receiver-transmitter (UART / ˈ juː ɑːr t /) is a peripheral device for asynchronous serial communication in which the data format and transmission speeds are configurable.

  9. Serial Peripheral Interface - Wikipedia

    en.wikipedia.org/wiki/Serial_Peripheral_Interface

    The SPI timing diagram shown is further described below: CPOL represents the polarity of the clock. Polarities can be converted with a simple inverter. SCLK CPOL=0 is a clock which idles at the logical low voltage. SCLK CPOL=1 is a clock which idles at the logical high voltage. CPHA represents the phase of each data bit's transmission cycle ...
