I want to use the TLV320AIC12k audio codec together with the
STR715F MCU: from the codec datasheet it is clear that it is better
to configure the codec as SPI master device and the MCU as SPI
STR71X BPSI seems not to be very flexible and I have some
When using BSPI in slave mode the BSPIn_CLK register should
be "don't care", but in the users manual we read "In slave mode
this number must be an even number greater than seven...".
Is there any relationship between the clock rate (generated
by the master device) and the prescaler value ?
Because I cannot use the /SS signal, to start the communication
I think use the interrupt routine triggered by the falling edge of
an incoming signal (e.g. P0.14). Do you think it is possible or I
will face with latency problems ? The maximum speed I foresee
is 22050 bps ans so the minimum distance from the falling edge
of the signal and the falling edge of the clock cycle is 22 usec.
