Hi guys
I have a slight problem and not sure how to sort it out, in my program I am saving 5 bites at a time to the the 24LC256
when i get to address 60 it writes 4 bites and dose not write bite five. Any suggestions on how to sort this

Hello Brian.
The 24LC256 has a page write buffer of 64 bytes
Therefore, you can only transmit 63 addresses at a time then you must use a stop condition.
That is why you are seeing the wrong value after 63 bytes.

Hi Martin

Thanks for the reply I get what you saying but what is confusing me is I'm not doing a 64 page bit write I'm only writing 5 bites. and it only dose it to me from bite 60 to 64. At bite 125 to 129 it works fine. That's what is confusing me, I have adjusted the software to over come this issue but just trying to understand why it only dos it at the end of the first 64 bites.

I posted a component many moons ago that handled page 'issues' automatically.

See https://matrixtsl.com/mmforums/viewtopi ... 523#p98523 I haven't tried it with v9 but if you give it a go and I'll try and help if there are any issues.

Note that - in your example it might be attempting to write the last byte to the start off the page
