The PWM period is 64 µs and there are 0x03FF (1023 decimal) steps within this period. When
M0
=
0
(0% PWM), 0x01FF (50% PWM), 0x03FF (100% PWM), and so forth.
Parameter range
0 - 0x3FF
Default
0
M1 (PWM1 Duty Cycle)
If
is set correctly and
is configured as PWM1
output, incoming AD0 samples automatically modify the PWM1 value. See
.
To configure the duty cycle of PWM1:
1. Enable PWM1 output (
P1
= 2).
2. Change
M1
to the desired value.
3. Apply settings (use
CN
or
AC
).
The PWM period is 64 µs and there are 0x03FF (1023 decimal) steps within this period. When
M1
=
0
(0% PWM), 0x01FF (50% PWM), 0x03FF (100% PWM), and so forth.
Parameter range
0 - 0x3FF
Default
0
RP (RSSI PWM Timer)
The PWM timer expiration in 0.1 seconds.
RP
sets the duration of pulse width modulation (PWM) signal
output on the RSSI pin. The pin signal duty cycle updates with each received packet and shuts off
when the timer expires. This command is only applicable when
P0
is set to
1
which enables RSSI PWM
output.
When
RP
=
0xFF
, the output is always on.
Parameter range
0 - 0xFF (x 100 ms), 0xFF
Default
0x28 (four seconds)
LT (Associate LED Blink Time)
Set or read the Associate LED blink time. If you use
D5 (DIO5/Associate Configuration)
to enable the
Associate LED functionality (DIO5/Associate pin), this value determines the on and off blink times for
the LED when the device has joined the network.
If
LT = 0
, the device uses the default blink rate: 500 ms for a sleep coordinator, 250 ms for all other
nodes.
