What are the four I2C modes of operation?
The I2C module may be configured to operate in the following modes: I2C slave, 7-bit addressing, I2C slave, 10-bit addressing, and. I2C master, 7- or 10-bit addressing.
What is I2C protocol?
I2C stands for Inter-Integrated Circuit. It is a bus interface connection protocol incorporated into devices for serial communication. It was originally designed by Philips Semiconductor in 1982. Recently, it is a widely used protocol for short-distance communication.
Where I2C protocol is 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.
CAN protocol I2C?
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.
What is the difference between I2C and CAN?
Most MCUs with i2c buses can only go upto 400 kHz. CAN is differential, and is more immune to noise. CAN only allows 8 bytes to be sent at a time, i2c is essentially unlimited (this can be good or bad depending on how you look at it). You can broadcast with i2c, although i2c uses node addresses for most messages.
What is the difference between UART and RS232?
UART is a communications protocol, whilst RS232 defines the physical signal levels. That is, while UART has everything to do with logic and programming, it has nothing to do with the electronics per se. Whilst RS232 refers to the electronics and hardware needed for serial communications.
What is CAN and how it works?
A Controller Area Network (CAN bus) is a robust vehicle bus standard designed to allow microcontrollers and devices to communicate with each other’s applications without a host computer.
Is CAN based on I2C?
I2c is synchronous and CAN is asynshronous. 2. i2c needs slave address and CAN does not need slave address protocol.
What is the I2C protocol?
PIC Microcontroller Communication with I2C Bus: A step by step guide to Master I2C Protocol and Start using it Who We Are? I²C Allows communication of data between I2C devices over two wires. which makes it easier for anyone to exchange information without too much wiring.
What is the difference between Cancan and I2C?
CAN is a message based protocol. I2C is a address based protocol. In CAN each node can behave as Master or Slave. *In I2C the slave device can’t be a master. Speed and distance also different. If you understand I2C arbitration rules and cause then understanding CAN will be efficient.
What is the difference between CAN bus and I2C bus?
CAN is differential, and is more immune to noise. CAN only allows 8 bytes to be sent at a time, i2c is essentially unlimited (this can be good or bad depending on how you look at it). Several MCUs have to communicate with each other. So the first bus is thought of were the CAN bus, but what about the I2C bus.
What are the advantages and disadvantages of I2C?
An I2C protocol has a lot of advantage but beside it, I2C has a few limitations. It consumes more power than other serial communication busses due to open-drain topology. It is good only for a short distance. I2C protocol has some limitation for the number of slaves, the number of the slave depends on the capacitance of the I2C bus.
