In AmigaOS one can use the i2c.resource component [25] 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.
IEEE-488.1 specified the physical and electrical bus, and IEEE-488.2 specified protocol and data format, but neither specified instrument commands. Different manufacturers, and even different models, of the same type of instrument would use different command sets. SCPI created a standard which could be common across all manufacturers and models.
SPI protocol being a de facto standard, some SPI host adapters also have the ability of supporting other protocols beyond the traditional 4-wire SPI (for example, support of quad-SPI protocol or other custom serial protocol that derive from SPI [34]).
The communication protocol describes two sets of instructions. The Display Command Set (DCS) is a set of common commands for controlling the display device, and their format is specified by the DSI standard. It defines registers that can be addressed and what their operation is. It includes basic commands such as sleep, enable, and invert display.
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.
It can mix various data streams, including SPI, I2C or Ethernet; 500 Mbit/s, 1 Gbit/s and 3 Gbit/s sustained downstream link bandwidth; 187.5 Mbit/s upstream link bandwidth; Single/dual channel LVDS 18 or 24 bit; Video resolution up to 1280x720x24bit (720p) / 2 x 1280x720x18 bit / 1600x600x24 bit @ 60 Hz; APIX3 logo. APIX3 [8] [9] adds higher ...
Boundary scan is a method for testing interconnects (wire lines) on printed circuit boards or sub-blocks inside an integrated circuit (IC).Boundary scan is also widely used as a debugging method to watch integrated circuit pin states, measure voltage, or analyze sub-blocks inside an integrated circuit.
Management Component Transport Protocol (MCTP) is a protocol designed by the Distributed Management Task Force (DMTF) to support communications between different intelligent hardware components that make up a platform management subsystem, providing monitoring and control functions inside a managed computer system.
