  2. Serial Peripheral Interface - Wikipedia

    en.wikipedia.org/wiki/Serial_Peripheral_Interface

    The key SPI parameters are: the maximum supported frequency for the serial interface, command-to-command latency, and the maximum length for SPI commands. It is possible to find SPI adapters on the market today that support up to 100 MHz serial interfaces, with virtually unlimited access length.

  3. NMEA 0183 - Wikipedia

    en.wikipedia.org/wiki/NMEA_0183

    NMEA 0183 is a combined electrical and data specification for communication between marine electronics such as echo sounder, sonars, anemometer, gyrocompass, autopilot, GPS receivers and many other types of instruments.

  4. Null-terminated string - Wikipedia

    en.wikipedia.org/wiki/Null-terminated_string

    This allows the string to contain NUL and made finding the length need only one memory access (O(1) (constant) time), but limited string length to 255 characters. C designer Dennis Ritchie chose to follow the convention of null-termination to avoid the limitation on the length of a string and because maintaining the count seemed, in his ...

  5. KISS (amateur radio protocol) - Wikipedia

    en.wikipedia.org/wiki/KISS_(amateur_radio_protocol)

    The length of time to keep the transmitter keyed after sending the data (in 10 ms units). 0x?5, 0x?? FullDuplex: 1: 0 means half duplex, anything else means full duplex. 0x?6, [...] SetHardware: Varies: Device dependent. 0xFF: Return: 0: Exit KISS mode. The TNC stops processing KISS protocol and returns to its vendor-specific behavior.

  6. Arduino Uno - Wikipedia

    en.wikipedia.org/wiki/Arduino_UNO

    The word "uno" means "one" in Italian and was chosen to mark a major redesign of the Arduino hardware and software. [7] The Uno board was the successor of the Duemilanove release and was the 9th version in a series of USB-based Arduino boards. [8] Version 1.0 of the Arduino IDE for the Arduino Uno board has now evolved to newer releases. [4]

  7. RS-422 - Wikipedia

    en.wikipedia.org/wiki/RS-422

    Data rate versus line length chart, from RS-422 Annex A.1. Several key advantages offered by this standard include the differential receiver, a differential driver and data rates as high as 10 megabits per second at 12 meters (40 ft). Since the signal quality degrades with cable length, the maximum data rate decreases as cable length increases.

    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.

  9. Universal asynchronous receiver-transmitter - Wikipedia

    Maximum standard speed of both of the 2692's channels is 115.2 kbit/s. The 26C92 is an upwardly compatible version of the 2692, with 8-byte transmitter and receiver FIFOs for improved performance during continuous bi-directional asynchronous transmission (CBAT) on both channels at the maximum standard speed of 230.4 kbit/s.
