Interface an sram bus for your arduino: 3 steps
go over the diagram proven here and connect your SRAM, making adjustments for the particular choice if IC. after you have everything connected, it’s only a matter of executing some code to allow your arduino speak with it.
The beginning code here’s lent in the blog of Jim Eli, at uc experiment because frankly his code was much better than mine, and most likely simpler to describe.
To create to memory, you initially drive the CS pin low, then over SPI send the write command (0x02) adopted through the 16 bit address you need to email. automatically, the lc512 has become prepared to take data, 8 bits at any given time, write them beginning in the address you provided, and increment the address by 1. should you keep writing past 0xFFFF it’ll simply rollover to 0x0000 and going. it’ll write as lengthy while you offer it data.

Studying from memory is essentially exactly the same factor. send 0x03 to see, the address you need to start studying at, after which inform your microcontroller to begin listening for that data being delivered to it. as lengthy while you keep listening, and delivering time signal, the SRAM could keep delivering data for you, looping with the memory addresses forever if you would like it to.
when you are done, just drive the CS pin high in order that it knows to seal up because you are completed with it. that’s what is needed to talk with SRAM over SPI. great, is not it? you can now add extra memory for your projects so that you can log data, or anything you require more RAM for. what if you want two chips? how can you do this? continue reading.
