#GPIO - General Purpose Input/Output Pin Control
AT#GPIO=[<pin>,
<mode>[,<dir>[,<save
]]]
Execution command sets the value of the general purpose output pin
GPIO<pin>
according to
<dir>
and
<mode>
parameter.
Not all configuration for the three parameters are valid.
Parameters:
<pin>
- GPIO pin number; supported range is from 1 to a value that depends on the
hardware.
<mode>
- its meaning depends on
<dir>
setting:
0 - no meaning if
<dir>=0
- INPUT
- output pin cleared to 0 (
Low
) if
<dir>=1
- OUTPUT
- no meaning if
<dir>=2, 3, 4, 5, 6
- ALTERNATE FUNCTION
1 - no meaning if
<dir>=0
- INPUT
- output pin set to 1 (
High
) if
<dir>=1
- OUTPUT
- no meaning if
<dir>=2, 3, 4, 5, 6
- ALTERNATE FUNCTION
2 - Reports the read value from the input pin if
<dir>=0
- INPUT
- Reports the read value from the input pin if
<dir>=1
- OUTPUT
- Reports a no meaning value if
<dir>=2
- ALTERNATE FUNCTION
3 - if
<dir>=0
– INPUT, enable Pull-Up
4 - if
<dir>=0
– INPUT, enable Pull-Down
<dir>
- GPIO pin direction
0 - pin direction is INPUT
1 - pin direction is OUTPUT
2,3,4,5,6 - pin direction is Alternate Function ALT1, ALT2, ALT3, ALT4, ALT5
