Hi All,
I am newer of Android and Linux. Now I am doing a task which
request to access GPIO in hwc.c or Surfaceflinger.cpp.
(I am using a panda board, and have light up it, now I want to
modify something).
But when I include the GPIO.h in hwc.c(hardware/ti/omap/), compile
error happen.
Anybody can give me some clue.
There is a gpio.h file in the kernel directory
/include/linux/gpio.h.
There is also a gpio-omap.c in kernel directory /driver/gpio/
My question is how to use it.
Should I change the kernel config (enable general GPIO) using
menuconfig, then rebuild it?
Vincent
