Hi all,
I'm trying to emulate a DS2505 and fill its eeprom with 795 bytes, I'm using arduino IDE 2 and arduino UNO board
The master is a medical machine wich use "search" command to find 2 onewire eeproms DS2505 and DS2430A, then it use "match" command many times to select the DS2505 and read 795 bytes by blocs, finally it stops reading by a reset pulse to continu with the DS2430A.
The real chip DS2505 is dead but I know its content, my purpose is to replace it with arduino board
If I fill the table mem_dummy[] with 574 bytes or less everything works fine, if I use a little bit more memory, the slave respond with wrong family code and data, and with 795 bytes, the slave won't work at all!

This is what I have changed for the configuration:

"setup OneWire" give the following error : 'Setup' was not declared in this scope Setup OneWire, so it is commented
image
I have commented many commands, so tell me if I have wrong
In DS2506.h, only MEM_SISE_PROPOSE is changed :

UPDATE : I still have the same issue with arduino uno and nano, but arduino mega 2560 and ESP-01 work fine, thanks very much for this library
Just I'am wordering if wifi is activated or not ESP-01 with this firmware? If yes, how to disable it?
