OK its obvious really. The 24C32 is a 32k BIT device not a 32k BYTE device!
Sorry to waste your time.
Perhaps for those not used to these devices it would help to describe it as 32k BIT not just 32k
Thanks
Andy

Re: Tiny RTC DS1307 + 24C32 Real Time Clock Module (HCMODU00
A ha! A much simpler test that shows the problem. It seems that addresses above 4k wrap in the library somewhere!

Re: Tiny RTC DS1307 + 24C32 Real Time Clock Module (HCMODU00
Hello, I am having trouble accessing the EEPROM. The following testcode code works fine for TESTLEN of up to 256 but does strange things in the first byte of each pair for TESTLEN 512 an up. The first byte seems to get some bits stuck at '1'. This doesn't make much sense on a serial device. I have t...
