Besides the buttons, there are 4 GND ports and another 10 analog touch input ports.
On the back of the board, there are 2 groups of pin headers including one group of GND,
and the other corresponding to the input of the 10 keys. They are reserved for extending
more control functions.
Check carefully, you can see the pin definition on touch input and pin headers are the same
with buttons and the joystick, meaning they can realize the same functions. For example, we
can connect the pins of Up, Down, Left, and Right of the touch input or pin headers to realize
the same control of the 4 directions by the joystick.
