Local SRAM library for 23AA04M chip
This library was forked from here. From the comments of this program:
Sample program to use a Serial SRAM chip to expand memory for an Arduino Portenta giving access to an additional 4Mbit of random access memory. The 23AA04M uses the Serial Peripheral Interface (SPI) to transfer data and commands between the UNO and the memory chip. Note that the functions could be extracted as a beginning for a library for this chip. [This is one such library - DD].
Used the following components:
(1) Arduino Portenta
(2) Microchip 23AA04M SPI SRAM chip soldered on a PCB
