// The #if directive prevent compile errors for Uno and Nano by excluding the 
//  HAL directives from the build.
#if !defined(IO_NO_HAL)


// Examples of statically defined HAL directives (alternative to the create() call).
// These have to be outside of the mySetup() function.


// The following directive defines a PCA9685 PWM Servo driver module.
// The parameters are: 
//   First Vpin=100
//   Number of VPINs=16 (numbered 100-115)
//   I2C address of module=0x40

//PCA9685 pwmModule1(100, 16, 0x40);


// The following directive defines an MCP23017 16-port I2C GPIO Extender module.
// The parameters are: 
//   First Vpin=164
//   Number of VPINs=16 (numbered 164-179)
//   I2C address of module=0x20

//MCP23017 gpioModule2(164, 16, 0x20);


// Alternative form, which allows the INT pin of the module to request a scan
// by pulling Arduino pin 40 to ground.  Means that the I2C isn't being polled
// all the time, only when a change takes place. Multiple modules' INT pins
// may be connected to the same Arduino pin.

//MCP23017 gpioModule2(164, 16, 0x20, 40);


// The following directive defines an MCP23008 8-port I2C GPIO Extender module.
// The parameters are: 
//   First Vpin=300
//   Number of VPINs=8 (numbered 300-307)
//   I2C address of module=0x22

//MCP23017 gpioModule3(300, 8, 0x22);


// The following directive defines a PCF8574 8-port I2C GPIO Extender module.
// The parameters are: 
//   First Vpin=200
//   Number of VPINs=8 (numbered 200-207)
//   I2C address of module=0x23

//PCF8574 gpioModule4(200, 8, 0x23);


// Alternative form using INT pin (see above)

//PCF8574 gpioModule4(200, 8, 0x23, 40);


// The following directive defines an HCSR04 ultrasonic module.
// The parameters are: 
//   Vpin=2000 (only one VPIN per directive)
//   Number of VPINs=1
//   Arduino pin connected to TRIG=30
//   Arduino pin connected to ECHO=31
//   Minimum trigger range=20cm (VPIN goes to 1 when <20cm)
//   Maximum trigger range=25cm (VPIN goes to 0 when >25cm)
// Note: Multiple devices can be configured by using a different ECHO pin
// for each one.  The TRIG pin can be shared between multiple devices.
// Be aware that the 'ping' of one device may be received by another
// device and position them accordingly!

// The function mySetup() is invoked from CS if it exists within the build.
// It is called just before mysetup.h is executed, so things set up within here can be
// referenced by commands in mySetup.h.

  // Alternative way of creating MCP23017, which has to be within the mySetup() function
  // The other devices can also be created in this way.  The parameter lists for the
  // create() function are identical to the parameter lists for the declarations.

  //MCP23017::create(180, 16, 0x21);


  // Creating a Turnout
  // Parameters: same as <T> command for Servo turnouts
  // ID and VPIN are 100, sonar moves between positions 102 and 490 with slow profile.
  // Profile may be Instant, Fast, Medium, Slow or Bounce.

  //ServoTurnout::create(100, 100, 490, 102, PCA9685::Slow);


  // DCC Accessory turnout
  // Parameters: same as <T> command for DCC Accessory turnouts
  //  ID=3000
  //  Decoder address=23
  //  Decoder subaddress = 1

  //DCCTurnout::create(3000, 23, 1);


  // Creating a Sensor
  // Parameters: As for the <S> command,
  //  id = 164,
  //  Vpin = 164 (configured above as pin 0 of an MCP23017)
  //  Pullup enable = 1 (enabled)

  //Sensor::create(164, 164, 1);


  // Way of creating lots of identical sensors in a range

  //for (int i=165; i<180; i++) 
  //  Sensor::create(i, i, 1);
