[En-Nut-Discussion] Adding/Modifying Device Drivers

[Andrew Mieczkowski]

Hello again,

     I apologize in advance for repeating some of the original
information, but I have done so in the attempt to add additional
specificity and clarity to my situation.

 

     I am using Nut/OS with an AT91SAM7XC256-EK board and I would like
to use the SPI as a communication method similar to the UART. I have the
Yagarto ARM toolchain installed, but I have been using the "make clean"
and "make install" to compile my program for the ARM so far.

 

    As the UART is so easily implemented, is there a similar driver for
SPI communication somewhere? I have extensively searched for SPI driver
implementations, but the only one I have been able to locate is the one
for a Memory Card. Although this driver exists, I seem to be unable to
modify the source and incorporate it into my project. When I was using
the Ethernut 2 board, I could always "rebuild all", but the method to do
so for the ARM seems to be eluding me. I have also seen mention of
modification of make files to perform various functions, but has also
not been as fruitful as I had hoped.

 

   Any assistance or a point in the right direction would be greatly
appreciated.

 

Thanks Again,
