The EEByteWrite function is defined as: Sign up using Email and Password. Home Questions Tags Users Unanswered. Xt24c16a only really for higher speed block transfers. The datasheet which I haven’t seen surely shows you the protocol used to address the memory?
He’s run into a problem in the library routines he is using rather than having a coding error per se. Are you just writing to page zero? See my comment on his answer.
As you can see the address parameter is an unsigned char which means it can only accept values up to I checked the datasheet and found three pins as p0p1p2 meaning page control pins. He’s trying to adapt, the question is reasonable and he needs encouraging. For example see this similar project which describes the I2C protocol.
To access more than addresses you will need to write your own routines that control the target chip appropriately. This is a typical trap for the uninitiated and the question is aat24c16a reasonable one.
According to the datasheet it must have addresses and I datasgeet be able to write unsigned int into it [ 1 unsigned int per 2 addresses] but I am only able to write unsigned ints onto addresses. The problem here is actually with the I2C peripheral library, not your code.
Email Required, but never shown. Roh 2, 5 27 It has 8 pages. But i still st24c16a figure that out It’s a shame to see this question not receiving a few upvotes.
