Re: Multiple i2c port drive & Multiple SPI port drive

a couple of things, u'd need to state the eeprom that you are using
if you're buying from the likes of aliexpress beware of some vendors selling boards with substitutes and labeling after the real original chips.
i'm not familiar with i2c hence have little to contribute here.
but that you've tried spi flash, and you may like to continue that attempt

i2c is 100-300 kbps max and unless you are keeping only a little data, you would likely run out of bandwidth trying to store adc data.
the main thing about i2c is using less wires, that's about it.
then you may like to try sdio that uses SPI, this won't be easier than the others,

it is in fact more complex due to dealing with a fat file system and sd cards. so you can expect more problems.
but then these days sd cards provides gigabytes of storage and that's the main attraction
