+MIOD, Motorola I/O Define
This command defines the H24 8 GPIO pins configuration. Factory default values are: all pins are
defined as an input.
Command
Type Syntax Response/Action Remarks
Set
AT+MIOD=,
[,]
OK
or:
+CME ERROR:
The set command defines the behavior
mode of each selected IO pin. The H24
saves the new setting in flex. The
selected pins are affected. Validity
check of all parameters will be done
and appropriate standard error will be
issued. In case of legal parameters the
new configuration is set. If is omitted and the new
is output, the pin will hold a
physical low signal. In case is supplied and includes values
of input pins, those values will be
ignored.
Read + MIOD? +MIOD:
OK
Test + MIOD=? +MIOD: (list of
supported s),(list of
supported
s),(list of
supported s)
OK
or:
+CME ERROR:
The read command returns the current
behavior mode of the 8 GPIO pins.
The test command returns the possible
ranges of s, s
and s.
:
This is a binary vector in which each bit shows the operation mode of the pins.
0 = pin is defined as an output pin.
1= pin is defined as an input pin.
This vector will be receive when MIOD read command is executed
