I2C SERIAL COMMUNICATION PROTOCOL HOW TO

When SCL is High, We have to toggle the SDA Low to High. Then we will read that data from EEPROM and send it to Serial Communication (UART). In our code, First, we will Write the Data into EEPROM.

Send again START command or Repeated START command.

Send Register address in Device (EEPROM), Where we have to access.

If you want to send more than one byte, keep sending that byte.

Send Device (EEPROM) Address with write mode.

Send the START command from the Master.

An EEPROM is a kind of non-volatile memory used in electronic devices like computers to store small quantities of data that should be saved when power is detached. EEPROMД®lectrically Erasable Programmable ROM (EEPROM) is a user-modifiable ROM that can be removed and reprogrammed frequently through the application of higher than the normal electrical voltage. For the sake of implementing Iв¬, we are going to interface EEPROM.

I2C SERIAL COMMUNICATION PROTOCOL HOW TO

So in this tutorial, we will see how to achieve that. Nowadays new microcontrollers have inbuilt Iв¬ Registers. Typical voltages used are +3.3V or +5V although systems with extra voltages are allowed.

Data is interchanged between these two devices. Iв¬ bus permits a master device to start communication with a slave device. Iв¬ bus uses two bidirectional open-drain lines such as SDA (serial data line) and SCl (serial clock line) and these are pulled up with resistors. The Iв¬ bus is used to attach low-speed peripheral integrated circuits to microcontrollers and processors. Iв¬ is a serial computer bus, which is invented by NXP semiconductors previously it is named as Philips semiconductors. 8051 -UART Interfacing Introduction Iв¬.6.6 Related 8051 I2C Interfacing Tutorial Suggestion to readД«efore getting into I2C interfacing with 8051, Please read the below topics.
