Topic: SPI Ram Question About reading (Read 537 times) previous topic - next topic


Okay, so the whole idea behind adding SPI RAM ICs to an Arduino is to increase the amount of RAM and store large variables or whatnot, but won't reading a value stored in the ICs just load the variable back into the microcontroller's SRAM?

Please let me know if I'm grossly misunderstanding the idea.


Yes, it will.

But you can e.g. save a long text received over serial byte-by-byte in SPI ram and later process it byte-by-byte.
If you understand an example, use it.
If you don't understand an example, don't use it.
