Now, if I could find out which device drivers exist for the eb40a
target. I have found the serial driver. But is there a driver for
the general IO pins? Or should I just go ahead and use the memory mapped
hardware?
There is no generic driver for GPIO pins. The are probably #defines
for them in the hal_plf.h file. Use those.
more specifically
hal/arm/at91/eb40a/current/include/plf_io.h
and hal/arm/at91/var/current/include/var_io.h
Look around in the at91/eb40a and at91/var HALs for mentions of PIO to see
how the pins are already configured and used.
