Good afternoon,
I'm trying to program a Quad CODEC from IDT reference 821034 through
SPI, and I'm having an issue:
The component requires 2 clock cycles in addition after setting CS back
to inactive state, otherwise the transmitted data is not latched in. I'm
wondering how I could do that easily in a Linux driver using the
standard SPI subsystem.
What I could do is to transmit a 2 bits data after setting CS to OFF
state, but how can I do that ?
Also, another issue I have is that between each byte I shall set CS to
OFF for at least 3 clock cycles. This can be done of course by sending
bytes one by one, but is there another easy way to do the same by
configuration ?
Regards
C. Leroy
