Photon flash memory expansion


How can I use an external SPI flash chip to expand Photons user memory


Depends on the chip used


Thanks ScruffR,
I was going to use W25Q64JVSSIM TR., 8 Megabyte flash
But please do make your own recommendation


This is a NOR flash hence SPIFFS or FatFs would be libraries to help with that.
Have a look at this
