DS2431 Difference behavior between real eeprom and arduino emulator #93

Closed x225am closed 3 years ago

x225am commented 3 years ago

Hi all, I have some devices with DS2431 eeprom I have read all info from it loaded in to the Arduino eeprom emulator. For some reason when I trying use this emulator in the real device it just would not accept it. I read with logic analayzer packets between master and eeprom and compare them with emulator. For some reason emulator would not respond on requests. Please have a look screens from the Analayzer: This is from original DS2431 eeprom Ashampoo_Snap_Sunday, 6 December 2020_22h59m06s_001_ And this one is from emulated. For some reason it only reset packets. Ashampoo_Snap_Sunday, 6 December 2020_23h01m23s_003_

cool that you have the needed tools and interest in getting this to run. unfortunately your screenshot does not tell much. its 99% a timing-problem (as usual). Well, i can only give you the same answer as yesterday: please read through the main readme. There is a dedicated help-section
