Parameters:
<pin>
<pin> <pin> <pin> - GPIO pin number; supported range is from 1 to a value that depends
on the hardware.
<mode> <mode> <mode> <mode> - its meaning depends on <dir> <dir> <dir> <dir> setting:
0 - no meaning if <dir>=0
<dir>=0 <dir>=0
<dir>=0 - INPUT
- output pin cleared to 0 (Low Low Low Low) if <dir>=1 <dir>=1 <dir>=1 <dir>=1 - OUTPUT
- no meaning if <dir>=2
<dir>=2 <dir>=2
<dir>=2 - ALTERNATE FUNCTION
1 - no meaning if <dir>=0 <dir>=0 <dir>=0 <dir>=0 - INPUT
- output pin set to 1 (High
High High
High) if <dir>=1
<dir>=1 <dir>=1
<dir>=1 - OUTPUT
- no meaning if <dir>=2 <dir>=2 <dir>=2 <dir>=2 - ALTERNATE FUNCTION
2 - Reports the read value from the input pin if <dir>=0
<dir>=0 <dir>=0
<dir>=0 - INPUT
- Reports the read value from the input pin if <dir>=1 <dir>=1 <dir>=1 <dir>=1 - OUTPUT
- Reports a no meaning value if <dir>=2
<dir>=2 <dir>=2
<dir>=2 - ALTERNATE FUNCTION
<dir> <dir> <dir> <dir> - GPIO pin direction
0 - pin direction is INPUT
1 - pin direction is OUTPUT
2 - pin direction is ALTERNATE FUNCTION (see Note).
Note: when <mode>=2
<mode>=2 <mode>=2
<mode>=2 (and <dir>
<dir> <dir>
<dir> is omitted) the command reports the
direction and value of pin GPIO<pin> GPIO<pin> GPIO<pin> GPIO<pin> in the format:
#GPIO: <dir>,<stat>
#GPIO: <dir>,<stat> #GPIO: <dir>,<stat> #GPIO: <dir>,<stat>
where:
<dir>
<dir> <dir>
<dir> - current direction setting for the GPIO<pin>
GPIO<pin> GPIO<pin>
GPIO<pin>
<stat> <stat> <stat> <stat>
•
logic value read from pin GPIO<pin>
GPIO<pin> GPIO<pin>
GPIO<pin> in the case the pin <dir>
<dir> <dir>
<dir> is set
to input;
•
logic value present in output of the pin GPIO<pin>
GPIO<pin> GPIO<pin>
GPIO<pin> in the case the pin
<dir> <dir> <dir> <dir> is currently set to output;
•
no meaning value for the pin GPIO<pin>
GPIO<pin> GPIO<pin>
GPIO<pin> in the case the pin <dir>
<dir> <dir>
<dir> is
set to alternate function.
Note: "ALTERNATE FUNCTION" value is valid only for following pins:
•
GPIO4
GPIO4 GPIO4
GPIO4 - alternate function is “RF Transmission Control”
•
GPIO5 GPIO5 GPIO5 GPIO5 - alternate function is “RF Transmission Monitor”
•
GPIO6
GPIO6 GPIO6
GPIO6 - alternate function is "Alarm Output" (see +CALA
+CALA +CALA
+CALA)
•
GPIO7 GPIO7 GPIO7 GPIO7 - alternate function is "Buzzer Output" (see #SRP #SRP #SRP #SRP)
•
GPIO10
GPIO10 GPIO10
GPIO10 – alterantive function is “DVI TX” (See #DVI)
•
GPIO12 GPIO12 GPIO12 GPIO12 – alternative function is “call key”
•
GPIO13
GPIO13 GPIO13
GPIO13 – alternative function is “ACTIVE”
•
GPIO17 GPIO17 GPIO17 GPIO17 – alternative function is “DVI SYNC” (See #DVI)
•
GPIO18
GPIO18 GPIO18
GPIO18 – alternative function is “DVI RX” (See #DVI)
