USB-8451 EEPROM

[NormanSim]

Hi there, I need help on writing & reading EEPROM using I2C. I tried to use USB-8451 (I2C) to write and read EEPROM (BR24L02-W from Rohm. However I only able to write & read the first 7 bytes of data. If the data written more than 7 bytes, I will read out data that is not in sequence (there isn't any error message) I have attached the VI that I used & the link to the EEPROM spec. http://pse.beganto.com/partdetailsrohm.do?description=&datasheet=http%3A%2F%2Fwww.rohm.com%2Fproducts%2Fdatabook%2Fgeneral%2Fpdf%2Fbr24l02-w-e.pdf&partno=BR24L02FV-W-E2&pid=524665 Thank you in advance for the reply. Best Regards, Norman

Hello,

Could you give me a sample of what kind of data you write, and what you read back? When you say the data is "not in sequence", does that mean you read the data you expect, but it is out of order? Or do you just read data that's incorrect? Thanks!

Regards,

I had the same problem with an EEPROM

I used General I2C write

Looks like you need to change the Target page size(bytes) from 128 to 8
