Sets a single control bit. The setting only takes
effect if the GPIO signal is not selected for a special
function operation and is configured to be an input.
The parameter after the TRIG keyword controls the
operation as follows:
Enable trigger if the specified GPIO signal
transitions from a 0 to a 1.
1 Enable trigger if the specified GPIO
transitions from a 1 to a 0
0 Enable trigger if the specified GPIO
transitions from a 0 to a 1
DIS Disable all triggers for the specified GPIO
signal.
<gpio-num> must be in the range 1-8.
NOTE: Setting a trigger condition resets all
undefined trigger strings for triggers that are
enabled to the default string value.
NOTE: The trigger configuration is not changed by
a configuration reset to default.
Shows current GPIO trigger conditions. Note that a
GPIO may be enabled for two trigger conditions,
one for a 0 to 1 transition, and one for a 1 to 0
transition. If a GPIO is set for its special function,
no trigger is possible on that pin.
Example:
Local> set gpio trig 1 1
Local> set gpio trig 0 2
Local> show gpio trig
GPIO Trigger Conditions
-----------------------
trig if GPIO #1 is 1 <Trig #1>
trig if GPIO #2 is 0 <Trig #2>
GPIO #2 is set for OUTPUT
GPIO #3 is set for OUTPUT
