6.7.1.10 #GGPI – Read General Purpose Input

#GGPI – read general purpose input

Execute command

Read command

AT#GGPI? Reports the read value for the input pin GPIO1in the format:

#GGPI: <dir>,<stat>

where

<dir> direction setting (see #GGPI=<dir> )

<stat> - logic value read from pin GPIO1

Note: Since the reading is done after the insulating transistor, the

reported value is the opposite of the logic status of the GPIO1 input

pin.

Write command

AT#GGPI = <dir> Set the General purpose input pin behavior depending on parameter

<dir>.

Parameter: <dir> - auxiliary input GPIO1 setting

<dir> = 0 - the read command reports the logic input level read from

GPIO1 pin.

<dir> = 1…255 - reserved for future use

Note: The device has an insulated input pin ( the input goes the base of

an internal decoupling transistor) which can be used as a logic general

purpose input. This command sets the read behaviour for this pin, since

only direct read report is supported, the issue of this command is not

needed.

In future uses the behavior of the read input may be more complex.
