Awesome content! Thank you so much for sharing your knowledge!!!

You declare dataAddress as byte in your write and read function. but you previously said the address was on 9 bits ! In your example you only write and read the 10 first address, so we cannot see what happen for addresses bigger that 255 ? How do we give your function addresses bigger than 255 ?

I see EEPROM on TV main board and on DVD mainboard. There was a time we were copying EEPROM logo from original TV to chinese unknown TVs. What else does the EEPROM do apart from storing logo?

could you tell me if this could be used to reset a 3d printer filament print cartridge?

realy a great video from you but just i would now the difference between the differnce eeproms ic ( exemple AT24CXX, 24CXX etc....)

Sorry for coming this late, but what can i use in circuitpython?

Question: if the address valueof type byte, how do you address the upper 256 bytes? Surely the value needs to be of type ushort.

Hi sir
Thank you for sharing
with your code we can just read and write 256 byte (just one block )
how can i read and write mor than 256 byte
My eeprom is 24lc04
