Set output GPIOs to 1:
# gpio − c 9 − s GPIO_DataOut − v 0x2aa
Check the GPIO levels: all must be at level 1 (because they are outputs at level 1, or because thay are inputs
connected to the outputs).
# gpio − c 9 − g GPIO_In
GPIO_In − > 0x000003FF
Set output GPIOs to 0:
# gpio − c 9 − s GPIO_DataOut − v 0x0
Check the GPIO levels: all must be at level 0 (because they are outputs at level 0, or because thay are inputs
connected to the outputs)
# gpio − c 9 − g GPIO_In
GPIO_In − > 0x00000000
#
>
To see the current value of all registers of a channel (binary and hex format), use the -u option. For
example:
# gpio − c 9 − u
