What's the currently preferred method for implementing all these.
Interrupt sampling of i2c sensors written to SPI flash, that periodically copies data to uSD.
And then write to uSD card from SPI flash by transferring to RAM first so as to not interfere with samples getting written to SPI flash.
Essentially, how do you avoid long waits on uSD card to not interfere with interrupt sampling?
