Have a ADC AD7193 chip, which is SPI , ish.
In particular the adc , uses its MISO pin , to indicate its ready.
in effect one does the spi transfer,
and then waits, with chip select still low, till the AD7913 takes MISO low.
then one can do the second transfer, and take chip select high.
I thought, digitalread( pin number of miso )
but that seems to always be returning high.
lots of testing to do, like get the scope out etc,
but anyone have any thoughts if one can read the MISO pin if its been defined in the SPI class.
using the normal SPI.h , on a teensy 3.6
Thanks
