3.3.4 GPIO_DEMO Instruction
a) Introduction
This software is only used for reference when developing GPIO functions of
device, and it isn't suitable for factory's standard software.
b) GPIO_DEMO Main Interface
Figure 2-1
c) Introduction of Main Components
The part marked with a red box in Figure 2-2. The "Name" in the first column
means the port names of GPIO. The "Direction" in the second column means
the input or output direction of the ports (Ps: It uses drop-down list control to
match the Direction value of corresponding GPIO ports with the actual situation
of device, ensure that the test software works normally, but not available for
adjusting the input or output state of the GPIO ports.). The "State" in the third
column means the current level state of the GPIO ports, it used to show the
level state of corresponding GPIO ports read by the software last time when
the direction of GPIO port is IN; The buttons on State column can set the level
state of corresponding GPIO ports when the direction of GPIO port is OUT.
