Example: How to Use Page Write Feature of I2C EEPROMs

[sayzer]

Hi Sayzer.

As the PBP manual states, the control byte must have bit 0 cleared. Is there any special reason that you have made it 1 in this command?

I2CREAD I2C_SDA, I2C_SCL,$A1,AdrR, [STR Mem\PageSize]

But here you still have it cleared:

I2CWRITE I2C_SDA, I2C_SCL,$A0,AdrW,[STR Mem\PageSize]

Hi Ioannis,

The way I read the data sheet of 24C512 eeprom, the write bit is 0 and the read bit is 1.
Same as 24LC64, 24LC512 also.

I agree that it is confusing, but it is a fact that for read operation either 0 or 1 works anyway.

[Ioannis]

Yes, the data sheet clearly states that bit 0 defines read or write. But PBP manual on I2C commands, says that this bit must be kept at 0. May be the compiler takes care of it. Anyway, I am sure it works just fine.

PBP handle the R/W bit for you.
