  2. 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]

  3. Asynchronous serial communication - Wikipedia

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

    Asynchronous start-stop is the lower data-link layer used to connect computers to modems for many dial-up Internet access applications, using a second (encapsulating) data link framing protocol such as PPP to create packets made up out of asynchronous serial characters. The most common physical layer interface used is RS-232D.

  4. NOP (code) - Wikipedia

    en.wikipedia.org/wiki/NOP_(code)

    NOPs are often involved when cracking software that checks for serial numbers, specific hardware or software requirements, presence or absence of hardware dongles, etc. in the form of a NOP slide. This process is accomplished by altering functions and subroutines to bypass security checks and instead simply return the expected value being ...

  5. AVR microcontrollers - Wikipedia

    en.wikipedia.org/wiki/AVR_microcontrollers

    The external data space is overlaid with the internal data space, such that the full 64 KB address space does not appear on the external bus and accesses to e.g. address 0100 16 will access internal RAM, not the external bus. In certain members of the XMega series, the external data space has been enhanced to support both SRAM and SDRAM.

    Arduino layout-compatible board, designed for use with a USB-TTL serial cable. DuinoBot v1.x [89] ATmega32U4 RobotGroup Argentina [90] Arduino fully compatible board, with integrated power supply and controllers designed for robotics. Compatible as well with the system "Multiplo" eJackino [91] Kit by CQ publisher in Japan.

  8. Serial communication - Wikipedia

    en.wikipedia.org/wiki/Serial_communication

    In telecommunication and data transmission, serial communication is the process of sending data one bit at a time, sequentially, over a communication channel or computer bus. This is in contrast to parallel communication , where several bits are sent as a whole, on a link with several parallel channels.

  9. Serial Peripheral Interface - Wikipedia

    en.wikipedia.org/wiki/Serial_Peripheral_Interface

    It is sometimes called a four-wire serial bus to contrast with three-wire variants which are half duplex, and with the two-wire I²C and 1-Wire serial buses. Typical applications include interfacing microcontrollers with peripheral chips for Secure Digital cards, liquid crystal displays , analog-to-digital and digital-to-analog converters ...
