What are the functions used to receive data over I2C?
I2C is an acknowledgment-based communication protocol i.e. transmitter checks for an acknowledgment from the receiver after transmitting data to know whether data is received by receiver successfully. I2Cworks in two modes namely, Master mode. Slave mode.
What are the advantages of I2C?
What Are the Advantages of I2C? I2C vs UART vs SPI
- maintains low pin/signal count even with numerous devices on the bus.
- adapts to the needs of different slave devices.
- readily supports multiple masters.
- incorporates ACK/NACK functionality for improved error handling.
How do I validate I2C?
Test and Validate Key I2C Features
- START and STOP condition generation.
- ACK and NACK condition generation.
- The response of the device under test in different states: idle, read, write, address_match, ACK.
- Synchronization of the clock between the master and slave.
- Validation of 7-bit address.
Where is I2C being used?
I2C Communication The I2C bus protocol is most commonly used in master and slave communication wherein the master is called “microcontroller”, and the slave is called other devices such as ADC, EEPROM, DAC and similar devices in the embedded system.
What is the main use of I2C?
The I2C protocol is used to establish communication between two or more ICs (Integrated Circuits), hence why it’s known as Inter-Integrated Circuit (I2C) communication. However, it should be noted that I2C could also be used as a communication protocol between two ICs that are located on the same PCB.
What is the application of I2C?
The I2C protocol is a serial communication protocol that is used to connect low-speed devices. For example, EEPROMs, microcontrollers, A/D and D/A converters, and input/output interfaces. It was developed by Philips semiconductor in 1980 for inter-chip communication. Almost all major IC manufacturers now use it.
What can I do with I2C communication protocol?
With I2C, you can connect multiple slaves to a single master (like SPI) and you can have multiple masters controlling single, or multiple slaves. This is really useful when you want to have more than one microcontroller logging data to a single memory card or displaying text to a single LCD.
How does a slave device work in I2C?
Each signal line in I2C contains pull-up resistors to restore the signal to a high of the wire when no device is pulling it low. All transfers are initiated and terminated by the “master device”; the “master device” can write data to one or more “slave devices” or request data from the “slave devices”.
What is the purpose of the I2C bus?
The I2C bus is a very popular and powerful bus used for communication between a master (or multiple masters) and a single or multiple slave devices. Figure 1 illustrates how many different peripherals may share a bus which is connected to a processor through only 2 wires, which is one of the largest benefits
Why is high speed mode used in I2C?
High-speed mode Speed is one of the factors that limit the I2C bus application. Using a pull-up resistor which sets a logic 1 limits the maximum transfer speed of the bus which is why the high-speed mode at a speed of 3.4 Mbit/s is introduced.
