24C02 I2C PDF

The programming and reading of I2C EEProms is one of the major uses of the as 2,4 or 8 separate 24C02 memories with sequential I2C sub-. I am trying to read and write I2C EEPROM (24C02 from Microchip) but i failed every-time. i am using Kohms as a pull up resistor in the I2C bus. My code is. Now the problem is: as I go through the datasheets of all such I2C serial memories there is a memory reset in that of AT24C02 which is not.

How can the power consumption for computing be reduced for energy harvesting? Just follow the sequence in the data sheet to reset the bus. Handy to check first if you are getting a connection with the device, try running the following code:.

Problem for reading and writting I2C Eeprom 24c02 6. This delay will be needed in fast microcontrollers, if you don’t delay you will read wrong data.

I will share you my i2c code using 24LC, it is very simple and doesn’t use interrupt, so it is easier to follow the flow.
