20.6 AT^SCCNT Configure Pulse Counter
The AT^SCCNT write command serves to configure the GPIO8 line as pulse counter. The pulse counter is
designed to measure signals from 0 to 1000 pulses per second. The measurement starts within <50ms after the
OK result code has been sent. If the pulse counter is controlled from Java this delay may, in rare cases and
depending on the system load, be longer.
Before execution of the AT^SCCNT write command take care that Pulse Counter functionality is enabled with
AT^SCFG="Gpio/mode/PULSE" set to "std". Remember that if the GPIO8 line is configured as GPIO (see
AT^SCPIN) any attempt to activate the pulse counter will be rejected. Vice versa, if the pulse counter is opened
the GPIO8 line cannot be configured as GPIO.
See also [2] for further detail on the pulse counter.
Syntax
Unsolicited Result Code
^SCCNT: <time>
The URC applies only to the Limit counter mode set with parameter <mode>=1. It is delivered once the pulse
counter has completed counting the number of pulses requested with parameter <limit>.

0 Close pulse counter
1 Open pulse counter
