What is I2C compatible interface?
I2C is a serial protocol for two-wire interface to connect low-speed devices like microcontrollers, EEPROMs, A/D and D/A converters, I/O interfaces and other similar peripherals in embedded systems. It was invented by Philips and now it is used by almost all major IC manufacturers.
How do I extend my I2C?
You can use a higher voltage to power the i2c extender chips and the buffered bus. That way, you could have a 3.3V micro controller and 3.3V sensor but get better range extension by running the range extenders and the buffered bus at 5V.
How can I make my I2C more robust?
The solution to reducing this problem is simple: all devices use a good grounding system and use a shielded cable for the bus. The use of a shielded cable for the bus is to help to suppress the EMI, but it has parasitic capacitances. The longer the cable, the bigger the capacitance.
What is the difference between I2C and can?
CAN is a message based protocol, designed specifically for automotive applications for the communication between the main host controller and other devices (also now in industrial automation ). It can be transferred to long distances. I2C is a short distance communication used between the ICs in a same circuit.
How long can an I2C bus be?
So the maximum bus length of an I2C link is about 1 meter at 100 Kbaud, or 10 meters at 10 Kbaud. Unshielded cable typically has much less capacitance, but should only be used within an otherwise shielded enclosure.
Does I2C need twisted pair?
In twisted pair cables, the I2C signals should be paired with power or GND wires, not with other I2C signals. In ribbon cables, the I2C signals should only be adjacent to power or GND wires. The length of the cable does normally not affect the amplitude of the crosstalk very much.
What is the I2C bus?
The I2C bus is a standard bidirectional interface that uses a controller, known as the master, to communicate with slave devices. A slave may not transmit data unless it has been addressed by the master. Each device on the I2C bus has a specific device address to differentiate between other devices that are on the same I2C bus.
What is an I2C microcontroller?
A particular strength of I 2 C is the capability of a microcontroller to control a network of device chips with just two general-purpose I/O pins and software. Many other bus technologies used in similar applications, such as Serial Peripheral Interface Bus (SPI), require more pins and signals to connect multiple devices.
Is there a standardized connector for I2C interconnects?
I 2 C does not employ a standardized connector, however, board designers have created various wiring schemes for I 2 C interconnections.
What is IIc (Inter-Integrated Circuit)?
I2C ( Inter-Integrated Circuit, eye-squared-C) and is alternatively known as I2C or IIC. It is a synchronous, multi-master, multi-slave, packet switched, single-ended, serial communication bus invented in 1982 by Philips Semiconductors.
