DIFFERENCE:
This section refers to the MMX4x2-HDMI-USB20-L model only.
6.7.1. Setting the Level and Direction for Each Pin
GPIO pins can be configured as follows. See more details about the GPIO connector in the
Purpose Input/Output Ports section and about the interface in the
Command and Response #gpio
 {GPIO<pin_nr>=<dir>;<level>}
 (GPIO<pin_nr>=<dir>;<level>)CrLf
Parameters
Parameter Parameter description
<pin_nr> GPIO pin number
<dir> The direction of the communication
<level> The level of the pin
Example
 {gpio1=O;H}
 (GPIO1=O;H)
GPIO pin 1 is set to output with high level.
INFO:
The current GPIO pin configuration can be queried by typing the {GPIO<pin_nr>=?} command.
