SparkFun_External_EEPROM.h question regards Arduino UNO connection

Other Miscellaneous
1

Hi, I am using both the SparkFun external EEPROM library and the associated example codes to successfully connect to an AT24C02C external EEPROM wired to an Arduino UNO. The device address for this EEPROM is 0x50 … and that is the device code in the .h library.

Problem is I also need to connect to another similar EEPROM that has a hardwired address of 0x53.

Of course SparkFun_External_EEPROM.h will not recognise it and … whilst I can see the relevant 0b101000 entry in the .h file … I cannot edit it.

I’m hoping I have not transgressed any forum guidelines in posting this query here … I was not certain where it would be most appropriate.

Can anybody suggest how to use/amend the library to connect to a device with A2, A1, A0 device bits that are non-zero?

Many thanks

just change myMem.begin() in the sketch to include your address. e.g. myMem.begin(0b1010011, Wire)

Fantastic Paul … worked as you suggested. Thank you so much!
