//
// To prevent this, temporarily rename it to mySetup.txt or similar.

//=======================================================================
// 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=196
// Number of VPINs=16 (numbered 196-211)
// I2C address of module=0x22
//MCP23017 gpioModule2(196, 16, 0x22);
// 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(196, 16, 0x22, 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
//MCP23008 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)

// 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.
//=======================================================================
void mySetup() {
// Alternative way of creating a module driver, 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(196, 16, 0x22);
//=======================================================================
// Play mp3 files from a Micro-SD card, using a DFPlayer MP3 Module.
//=======================================================================
// Parameters:
// 10000 = first VPIN allocated.
// 10 = number of VPINs allocated.
// Serial1 = name of serial port (usually Serial1 or Serial2).
// With these parameters, up to 10 files may be played on pins 10000-10009.
// Play is started from EX-RAIL with SET(10000) for first mp3 file, SET(10001)
// for second file, etc. Play may also be initiated by writing an analogue
// value to the first pin, e.g. SERVO(10000,23,0) will play the 23rd mp3 file.
// SERVO(10000,23,30) will do the same thing, as well as setting the volume to
// 30 (maximum value).
// Play is stopped by RESET(10000) (or any other allocated VPIN).
// Volume may also be set by writing an analogue value to the second pin for the player,
// e.g. SERVO(10001,30,0) sets volume to maximum (30).
// The EX-RAIL script may check for completion of play by calling WAITFOR(pin), which will only proceed to the
// following line when the player is no longer busy.
// E.g.
// SEQUENCE(1)
// AT(164) // Wait for sensor attached to pin 164 to activate
// SET(10003) // Play fourth MP3 file
// LCD(4, "Playing") // Display message on LCD/OLED
// WAITFOR(10003) // Wait for playing to finish
// LCD(4, " ") // Clear LCD/OLED line
// FOLLOW(1) // Go back to start
// DFPlayer::create(10000, 10, Serial1);
//=======================================================================
// Remote (networked) VPIN Configuration
//=======================================================================
// Define remote pins to be used. The range of remote pins is like a common data area shared
// between all nodes.
// For outputs, a write to a remote VPIN causes a message to be sent to another node, which then performs
// the write operation on the device VPIN that is local to that node.
// For inputs, the state of remote input VPIN is read on the node where it is connected, and then
// sent to other nodes in the system where the state is saved and processed. Updates are sent on change, and
// also periodically if no changes.
//
// Currently, analogue inputs are not enabled for remote access.
//
// Each definition is a triple of remote node, remote pin, type, indexed by relative pin.
// Each pin may be an input whose value is to be read before being transmitted (RPIN_IN),
// an output which is to be triggered when written to (RPIN_OUT) or both (RPIN_INPUT),
// such as a servo or DFPlayer device pin. Unused pins (e.g. spares to reserve contiguous
// pin sequences) should be defined sd VPIN_NONE with 0 as the type.
// Where possible, align the input and inout pins on an offset which is a multiple of 8
// from the start of the remote pins, as in the example below.
//
// There is a limit of 224 in the number of pin states per node that are sent
// over the network (to keep the number of sent messages to 1 x 32 bytes). This restriction
// may be lifted in future.
//
// In the example below with two nodes 30 and 31,
// a turnout object set to operate pin 4004 will operate the servo connected to
// VPIN 100 on node 30;
// a sensor object monitoring pin 4024 will trigger if pin D24 on node
// 31 activates;
// an output object associated with pin 4002 will, when set on, activate
// pin 166 (MCP23017 pin 3) on node 30.
//
// All nodes on the same network should use the same REMOTEPINS setup, and the
// node number of each node should be set to a different number.
//

// {30,164,RPIN_IN} , //4000 Node 30, first MCP23017 pin, input
