GPIO Flash Table
Parm1
P
arm2
Bits 16 – 31 determine the low signal
state while bits 0 – 15 determine the
high signal state. A value of 0 for bits
16 – 31 indicates the GPIO will
remain in low signal state for the
same amount of time as the high
signal state (50% duty cycle). The
high or low states are measured in
multiples of ¼ seconds. The toggle
count is set by Parm2
The flashing GPIO event will cause the
GPIO output state to toggle at time 0 to
the opposite state prior to starting the
GPIO output flash event processing.
This counts as toggle #1. An even
number of toggle count will force a
final state which is the same as the
initial state. An odd number of toggle
count will force the final state to be
opposite of the initial GPIO output
condition. 0 = toggle forever.
Bit-Field Table
The Parm2 value is obtained as a result of selecting individual bit-fields
from the table below.
Bit 31 Bit 30 Description
0 0 Table selector 0. Format message based on Parm2 values
using Message Format Table 0 (legacy format)
0 1 Table selector 1. Format message based on Parm2 values
using Message Format Table 1.
1 0 Table selector 2. Format message based on Parm2 values
using Message Format Table 2.
1 1 Table selector 3. Format message based on Parm2 values
using Message format Table 3.
Parm2 value is obtained as a result of selecting individual bit-fields from
the table below.
Message Format Table 0 – Legacy Format (0,0)
Parm2
Bit 0: 1 = send all data generated as a result of this table in Binary
format
0 = send all data generated as a result of this table in ASCII
format
Bit 1: 1 = add parm1 data to UDP message (4 – bytes in Binary
format, 11 – bytes of data in ASCII format)
0 = do not add parm1 data to outbound UDP message
Bit 2: 1 = add $MDMID value (22 – bytes of ASCII data – irrespective
of Bit– 0 setting)
0 = do not add $MDMID value
Bit 3: 1 = add $IOCFG and $IOGPA (GPIO 1 - 8 direction and data) in
ASCII-HEX format (2 – bytes in Binary format, 6 – bytes in
ASCII format)
0 = do not add GPIO direction and data value.
