#163660 - what I meant Responding to: ???'s previous message |
Have you tried writing a single byte of data with double byte address and read it back to make sure it works before starting page write and read?
Also verify with a scope that your clock is 400kHz. If you have a digital scope you could use it to see what is goining on in the read / write process. Mahmood |
