Dear RIOT developers,
I think it is not a good idea to initilialize the SPI interface
automatically via the periph_init() function because it is not as static
as mentioned.
In my application I have 2 SPI interfaces defined in the periph_conf.h
file - but I wanted only to configure the second one of these interfaces.
I the older days everything went well, but when I pulled in the new
sources I was wondering why now the spi_init() function was invoked 3
times....2 times automatically by the periph_init() function
(initializing all defined interfaces) and one time by my own
(initializing only the second interface).....and it took some time to
find out what was going wrong.
For my opinion interface initialization should be under control of the
application which interface is set up.
Best regards,
Neo
