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.

The Byte Write operation to the AT24C02 requires 7 42c02 device address, one byte memory addressand one or more bytes of memory data. However, I want you to confirm that your write byte and read byte function work properly or not the ones that you said they worked.

If you observed i2v waveform you will find that only first data was written. Read this before posting a programming question Don’t use “copy for forum” in the IDE.

I will share you my i2c code using i22c, it is very simple and doesn’t use interrupt, so it is easier to follow the flow. I checked the wave forms on DSO. In reply to sagar:.
