sram_read_write_test
The sample program demonstrates the use of the library to clear memory and then write a data structure to it and subsequently read that structure from memory. It is written using the standard Arduino IDE, which will also work with the standard Atmel Studio software. Communications between the Arduino and the memory is done via SPI (Serial peripheral interface) which uses 4 pins. There is one pin for input data (MISO), one for output data (MOSI), one for the system clock (SCL or SCK) and one pin used to select the specific device.
