In AmigaOS one can use the i2c.resource component [24] for AmigaOS 4.x and MorphOS 3.x or the shared library i2c.library by Wilhelm Noeker for older systems. Arduino developers can use the "Wire" library. CircuitPython and MicroPython developers can use the busio.I2C or machine.I2C classes respectively.
A typical hardware setup using two shift registers to form an inter-chip circular buffer. To begin communication, the SPI master first selects a slave device by pulling its SS low. (Note: the bar above SS indicates it is an active low signal, so a low voltage means "selected", while a high voltage means "not selected")
LIN (Local Interconnect Network) is a network protocol used for communication between components in modern vehicles. It is a low-cost single-wire serial protocol that supports communications up to 19.2 Kbit/s with a maximum bus length of 40 metres (131.2 ft).
The current I3C Hub specification is defined by Intel. The hub attaches onto a I²C/SMBus or I3C bus and presents as two targets. The hub can be connected to up to 8 target devices, either I²C/SMBus or I3C. When needed, the hub translates between the two protocols by buffering data. [27]

Integrated open-source debugging cable for fast prototyping. The first Arduino Shield Compatible board with two Arduino slots to add more and more shields. BigBrother-USB [277] Freescale MCF51JM128
Synchronous Serial Interface (SSI) is a widely used serial interface standard for industrial applications between a master (e.g. controller) and a slave (e.g. sensor). SSI is based on RS-422 [1] standards and has a high protocol efficiency in addition to its implementation over various hardware platforms, making it very popular among sensor manufacturers.
For example, the bidirectional I²C bus uses pull-up resistors on its two shared communication lines. When not transmitting, devices present a Hi-Z output to effectively "release" control over the communication lines. When all devices on the bus are Hi-Z, the only influence on the circuit is the pull-up resistors, which pull the lines high.
