Connecting Serial RAM

swThere are certain applications that need more RAM than IQRF TR module can provide. Then a SPI serial RAM comes in handy.

A library described below uses bit banging technique to connect serial SPI RAM to any free MCU pins thus keeping SPI slave interface free for other purposes. In our example we use 256K memory 23A256/23K256 from MICROCHIP. A different type with the same protocol or different capacity can be used too.
