[sdiy] New SPI SRAM

[Tom Wiltshire]

Excellent! Someone was asking me about how to increase the delay length for my dsPIC Digidelay project the other day, and that would be a simple solution. The current design uses two 23LC1024’s for 4 seconds of delay memory at 32KHz. That would push it out to 16 seconds without a lot of other changes beyond tweaking the addressing (e.g. no extra chip select lines or other hardware changes).
