Expand description
Full duplex (master mode)
Notes
-
It’s the task of the user of this interface to manage the slave select lines
-
Due to how full duplex SPI works each
read
call must be preceded by asend
call. -
Some SPIs can work with 8-bit and 16-bit words. You can overload this trait with different
Word
types to allow operation in both modes.
