GL_JoyStickStateIOEXP HAL function

Table 71 describes the GL_JoyStickStateIOEXP function of the hardware abstraction layer.

4.6.33

GL_JoyStickStatePolling HAL function

The state acquisition of the joystick is implemented by reading the relative pins with a period

of 50 ms in order to easily recognize if one of the joystick commands has been activated for

a long period of time.

Table 72 describes the GL_JoyStickStatePolling function of the hardware abstraction layer.
