Returns

This function returns the value of the analog channel mentioned as the function’s argument as a signed chartype. The value returned will range between -128 and 127, proportionally to the position of the joystick or trigger. The returned value will be:

• -128, if the joystick

  • Joystick is at the maximum left position (for x axis channels)

  or maximum down

  • Joystick is at the maximum up position (for y axis channels)

  • Trigger is fully unpressed

• 0, if the joystick/trigger is at the middle position of the axis, or if no connection is established between a remote controller and the CrcDuino (via a CrcConnect Module)

• 127, if the joystick

  • Joystick is at the maximum right position (for x axis channels)

  or maximum up

  • Joystick is at the maximum down position (for y axis channels)

  • Trigger is fully pressed

Main prototype and parameters

static int8_t Crc:: CrcLib::ReadAnalogChannel(ANALOG channel)

The following parameters must be passed to the function for it to work properly:

• channel: The name of the joystick channel you want to read the value of. Must be of the type ANALOG.

Overloads

This function does not have any overloads. It can only be used as described by the main prototype.

Examples

#include <CrcLib.h>

using namespace Crc;

signed char joystickValue;

void setup() {
    CrcLib::Initialize();
    
    Serial.begin(2000000);  //Open the serial Monitor at a 2000000 baud rate
    
    /* 
    The rest of your setup code
    ...
     */
}
void loop() {
    CrcLib::Update();

    joystickValue = CrcLib::ReadAnalogChannel(ANALOG::JOYSTICK1_X);
    Serial.println(joystickValue);
    /* 
    The rest of your looping code
    ...
    */
}
