Joystick12 Class Reference

API for the ElecFreaks* Joystick v 1.2-1.4 Breakout. More...

Detailed Description

• ID: joystick12
• Name: 2-axis Analog Joystick
• Category: ainput
• Manufacturer: generic
• Connection: analog
• Kit: robok

This module defines the Joystick API, and implementation for the X and Y buttons could be treated as normal GPIO - this enables easier interrupt support. This driver should be compatible with any 2-axis analog joystick.

int
main(int argc, char** argv)
{
    // Instantiate a joystick on analog pins A0 and A1
    upm::Joystick12 sensor(0, 1);
    signal(SIGINT, sig_handler);

    // Print the X and Y input values every second
    while (!is_running) {
        float x = sensor.getXInput();
        float y = sensor.getYInput();
        std::cout << "Driving X:" << x << ": and Y:" << y << std::endl;
        upm_delay(1);
    }

    std::cout << "exiting application" << std::endl;

    return 0;
}
