  2. I²C - Wikipedia

    en.wikipedia.org/wiki/I²C

    Below is an example of bit-banging the I 2 C protocol as an I 2 C controller (master). The example is written in pseudo C . It illustrates all of the I 2 C features described before (clock stretching, arbitration, start/stop bit, ack/nack).

  3. Power Management Bus - Wikipedia

    en.wikipedia.org/wiki/Power_Management_Bus

    The Power Management Bus (PMBus) is a variant of the System Management Bus (SMBus) which is targeted at digital management of power supplies.Like SMBus, it is a relatively slow speed two wire communications protocol based on I²C.

  4. System Management Bus - Wikipedia

    There is no limit in the I²C-bus protocol as to how long this delay can be, whereas for an SMBus system, it would be limited to 35 ms. The SMBus protocol just assumes that if something takes too long, then it means that there is a problem on the bus and that all devices must reset in order to clear this mode.

  5. Wishbone (computer bus) - Wikipedia

    en.wikipedia.org/wiki/Wishbone_(computer_bus)

    To prevent preemption of its technologies by aggressive patenting, the Wishbone specification includes examples of prior art, to prove its concepts are in the public domain. A device does not conform to the Wishbone specification unless it includes a data sheet that describes what it does, bus width, utilization, etc. Promoting reuse of a ...

  6. FPD-Link - Wikipedia

    en.wikipedia.org/wiki/FPD-Link

    FPD-Link III's embedded control channel uses the I2C bus protocol between the source and destination in the first implementations (however, it is not limited to I2C). The I2C master can read and write to all the slaves on the other side of the FPD-Link III chipset, which is effectively transparent to the I2C master and slaves communications.

  7. Master–slave (technology) - Wikipedia

    en.wikipedia.org/wiki/Master–slave_(technology)

    I2C and I3C are also an example of master-slave technology. Modbus uses a master device to initiate connection requests to slave devices. An edge-triggered flip-flop can be created by arranging two gated latches in a master–slave configuration. It is so named because the master latch controls the slave latch's value and forces the slave latch ...

  8. List of interface bit rates - Wikipedia

    en.wikipedia.org/wiki/List_of_interface_bit_rates

    The maximum goodput (for example, the file transfer rate) may be even lower due to higher layer protocol overhead and data packet retransmissions caused by line noise or interference such as crosstalk, or lost packets in congested intermediate network nodes. All protocols lose something, and the more robust ones that deal resiliently with very ...

  9. Bit banging - Wikipedia

    en.wikipedia.org/wiki/Bit_banging

    Bit banging allows a device to implement different protocols with minimal or no hardware changes. In some cases, bit banging is made feasible by newer, faster processors because more recent hardware operates much more quickly than hardware did when standard communications protocols were created.
