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.
A beat in a burst transfer is the number of write (or read) transfers from master to slave, that takes place continuously in a transaction. In a burst transfer, the address for write or read transfer is just an incremental value of previous address.
With multiple sub devices, a multidrop configuration requires an independent CS signal from the main for each sub device, while a daisy-chain configuration only requires one CS signal. Every sub on the bus that has not been selected should disregard the input clock and MOSI signals.
An example SPI with a master and three slave select lines. Note that all four chips share the SCLK, MISO, and MOSI lines but each slave has its own slave select. Chip select (CS) or slave select (SS) is the name of a control line in digital electronics used to select one (or a set) of integrated circuits (commonly called "chips") out of several connected to the same computer bus, usually ...
0x01 : Unit identifier (slave address) 0x03 : Function code (Read Multiple Holding Registers) 0x00 and 0x01 : high byte and low byte of the register address to read. The register address to read in this case is 0x0001. 0x00 and 0x01 : high byte and low byte of the number of registers to read. The number of registers to read in this case is ...
SMBus requires devices to acknowledge their own address always, as a mechanism to detect a removable device's presence on the bus (battery, docking station, etc.) I²C specifies that a slave device, although it may acknowledge its own address, may decide, some time later in the transfer, that it cannot receive any more data bytes.
ATmega328 is commonly used in many projects and autonomous systems where a simple, low-powered, low-cost micro-controller is needed. Perhaps the most common implementation of this chip is on the popular Arduino development platform, namely the Arduino Uno, Arduino Pro Mini [4] and Arduino Nano models.
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.
