// Enable/disable joystick functions.
//
// This controls whether or not we send joystick reports to the PC with the 
// plunger and accelerometer readings.  By default, this is enabled.   If
// you want to use two or more physical KL25Z Pinscape controllers in your
// system (e.g., if you want to increase the number of output ports
// available by using two or more KL25Z's), you should disable the joystick
// features on the second (and third+) controller.  It's not useful to have
// more than one board reporting the accelerometer readings to the host -
// doing so will just add USB overhead.  This setting lets you turn off the
// reports for the secondary controllers, turning the secondary boards into
// output-only devices.
//
// Note that you can't use button inputs on a controller that has the
// joystick features disabled, because the buttons are handled via the
// joystick reports.  Wire all of your buttons to the primary KL25Z that
// has the joystick features enabled.
//
// To disable the joystick features, just comment out the next line (add
// two slashes at the beginning of the line).

// Accelerometer orientation.  The accelerometer feature lets Visual Pinball 
// (and other pinball software) sense nudges to the cabinet, and simulate 
// the effect on the ball's trajectory during play.  We report the direction
// of the accelerometer readings as well as the strength, so it's important
// for VP and the KL25Z to agree on the physical orientation of the
// accelerometer relative to the cabinet.  The accelerometer on the KL25Z
// is always mounted the same way on the board, but we still have to know
// which way you mount the board in your cabinet.  We assume as default
// orientation where the KL25Z is mounted flat on the bottom of your
// cabinet with the USB ports pointing forward, toward the coin door.  If
// it's more convenient for you to mount the board in a different direction,
// you simply need to select the matching direction here.  Comment out the

// LedWiz default unit number.
//
// Each LedWiz device has a unit number, from 1 to 16.  This lets you install
// more than one LedWiz in your system: as long as each one has a different
// unit number, the software on the PC can tell them apart and route commands 
// to the right device.
//
// A *real* LedWiz has its unit number set at the factory; they set it to
// unit 1 unless you specifically request a different number when you place
// your order.
//
// For our *emulated* LedWiz, we default to unit #8.  However, if we're set 
// up as a secondary Pinscape controller with the joystick functions turned 
// off, we'll use unit #9 instead.  
//
// The reason we start at unit #8 is that we want to avoid conflicting with
// any real LedWiz devices you have in your system.  If you have a real
// LedWiz, it's probably unit #1, since that's the default factory setting
// that they'll give you if you didn't specifically ask for something else
// when you ordered it.  If you have two real LedWiz's, they're probably 
// units #1 and #2.  If you have three... well, I don't think anyone 
// actually has three, but if you did it would probably be unit #3.  And so 
// on.  That's why we start at #8: it seems really unlikely that anyone
// with a pin cab has a real LedWiz unit #8.  On the off chance that you
// do, simply change the setting here to a different unit number that's not 
// already used in your system.
//
// Note 1:  the unit number here is the *user visible* unit number that
// you use on the PC side.  It's the number you specify in your DOF
// configuration and so forth.  Internally, the USB reports subtract
// one from this number - e.g., nominal unit #1 shows up as 0 in the USB
// reports.  If you're trying to puzzle out why all of the USB reports
// are all off by one from the unit number you select here, that's why.
//
// Note 2:  the DOF Configtool (google it) knows about the Pinscape 
// controller.  There it's referred to as simply "KL25Z" rather than 
// Pinscape Controller, but that's what they're talking about.  The DOF 
// tool knows that it uses #8 as its default unit number, so it names the 
// .ini file for this controller xxx8.ini.  If you change the unit number 
// here, remember to rename the DOF-generated .ini file to match, by 
// changing the "8" at the end of the filename to the new number you set 
// here.

// Physical pixel count for your sensor.  This software has been tested with
// TAOS TSL1410R (1280 pixels) and TSL1412R (1536 pixels) sensors.  It might
// work with other similar sensors as well, but you'll probably have to make
// some changes to the software interface to the sensor if you're using any
// sensor outside of the TAOS TSL14xxR series.
//

// sample every pixel from the sensor on each scan, because (a) we don't
// have to, and (b) we don't want to.  We don't have to sample all of the
// pixels because these sensors have much finer resolution than we need to
// get good results.  On a typical pinball cabinet setup with a 1920x1080
// HD TV display, the on-screen plunger travel distance is about 165 pixels,
// so that's all the pixels we need to sample for pixel-accurate animation.
// Even so, we still *could* sample at higher resolution, but we don't *want*
// to sample more pixels than we have to,  because reading each pixel takes 
// time.  The limiting factor for read speed is the sampling time for the ADC 
// (analog to digital  converter); it needs about 20us per sample to get an 
// accurate voltage reading.  We want to animate the on-screen plunger in 
// real time, with minimal lag, so it's important that we complete each scan 
// as quickly as possible.  The fewer pixels we sample, the faster we 
// complete each scan.
//
// Happily, the time needed to read the approximately 165 pixels required
// for pixel-accurate positioning on the display is short enough that we can
// complete a scan within the cycle time for USB reports.  USB gives us a
// whole separate timing factor; we can't go much *faster* with USB than
// sending a new report about every 10ms.  The sensor timing is such that
// we can read about 165 pixels in well under 10ms.  So that's really the
// sweet spot for our scans.
//
// Note that we distribute the sampled pixels evenly across the full range
// of the sensor's pixels.  That is, we read every nth pixel, and skip the
// ones in between.  That means that the sample count here has to be an even
// divisor of the physical pixel count.  Empirically, reading every 8th
// pixel gives us good results on both the TSL1410R and TSL1412R, so you
// shouldn't need to change this if you're using one of those sensors.  If
// you're using a different sensor, you should be sure to adjust this so that

// Pseudo "Launch Ball" button.
//
// Zeb of zebsboards.com came up with a clever scheme for his plunger kit
// that lets the plunger simulate a Launch Ball button for tables where
// the original used a Launch button instead of a plunger (e.g., Medieval 
// Madness, T2, or Star Trek: The Next Generation).  The scheme uses an
// LedWiz output to tell us when such a table is loaded.  On the DOF
// Configtool site, this is called "ZB Launch Ball".  When this LedWiz
// output is ON, it tells us that the table will ignore the analog plunger
// because it doesn't have a plunger object, so the analog plunger should
// send a Launch Ball button press signal when the user releases the plunger.
// 
// If you wish to use this feature, you need to do two things:
//
// First, adjust the two lines below to set the LedWiz output and joystick
// button you wish to use for this feature.  The defaults below should be
// fine for most people, but if you're using the Pinscape controller for
// your physical button wiring, you should set the launch button to match
// where you physically wired your actual Launch Ball button.  Likewise,
// change the LedWiz port if you're using the one below for some actual
// hardware output.  This is a virtual port that won't control any hardware;
// it's just for signaling the plunger that we're in "button mode".  Note
// that the numbering for the both the LedWiz port and joystick button 
// start at 1 to match the DOF Configtool and VP dialog numbering.
//
// Second, in the DOF Configtool, make sure you have a Pinscape controller
// in your cabinet configuration, then go to your Port Assignments and set
// the port defined below to "ZB Launch Ball".
//
// Third, open the Visual Pinball editor, open the Preferences | Keys
// dialog, and find the Plunger item.  Open the drop-down list under that
// item and select the button number defined below.
//
// To disable this feature, just set ZBLaunchBallPort to 0 here.

const int ZBLaunchBallPort = 32;
const int LaunchBallButton = 24;

// Distance necessary to push the plunger to activate the simulated 
// launch ball button, in inches.  A standard pinball plunger can be 
// pushed forward about 1/2".  However, the barrel spring is very
// stiff, and anything more than about 1/8" requires quite a bit
// of force.  Ideally the force required should be about the same as 
// for any ordinary pushbutton.
//
// On my cabinet, empirically, a distance around 2mm (.08") seems
// to work pretty well.  It's far enough that it doesn't trigger
// spuriously, but short enough that it responds to a reasonably
// light push.
//
// You might need to adjust this up or down to get the right feel.
// Alternatively, if you don't like the "push" gesture at all and
// would prefer to only make the plunger respond to a pull-and-release
// motion, simply set this to, say, 2.0 - it's impossible to push a 
// plunger forward that far, so that will effectively turn off the 
// push mode.

// TLC5940 PWM controller chip setup - Enhanced LedWiz emulation
//
// By default, the Pinscape Controller software can provide limited LedWiz
// emulation through the KL25Z's on-board GPIO ports.  This lets you hook
// up external devices, such as LED flashers or solenoids, to the KL25Z
// outputs (using external circuitry to boost power - KL25Z GPIO ports
// are limited to a meager 4mA per port).  This capability is limited by
// the number of available GPIO ports on the KL25Z, and even smaller limit
// of 10 PWM-capable GPIO ports.
//
// As an alternative, the controller software lets you use external PWM
// controller chips to control essentially unlimited channels with full
// PWM control on all channels.  This requires building external circuitry
// using TLC5940 chips.  Each TLC5940 chip provides 16 full PWM channels,
// and you can daisy-chain multiple TLC5940 chips together to set up 32, 
// 48, 64, or more channels.
//
// If you do add TLC5940 circuits to your controller hardware, use this
// section to configure the connection to the KL25Z.
//
// Note that if you're using TLC5940 outputs, ALL of the outputs must go
// through the TLC5940s - you can't mix TLC5940s and the default GPIO
// device outputs.  This lets us take GPIO ports that we'd normally use
// for device outputs and reassign them to control the TLC5940 hardware.

// Joystick button input pin assignments.

// You can wire up to 32 GPIO ports to buttons (equipped with

// GPIO port and ground (J9 pin 12 or 14).  When the button is pressed, 
// we'll tell the host PC that the corresponding joystick button is 
// pressed.  We debounce the keystrokes in software, so you can simply 
// wire directly to pushbuttons with no additional external hardware.
//
// Note that we assign 24 buttons by default, even though the USB
// joystick interface can handle up to 32 buttons.  VP itself only
// allows mapping of up to 24 buttons in the preferences dialog 
// (although it can recognize 32 buttons internally).  If you want 
// more buttons, you can reassign pins that are assigned by default
// as LedWiz outputs.  To reassign a pin, find the pin you wish to
// reassign in the LedWizPortMap array below, and change the pin name 
// there to NC (for Not Connected).  You can then change one of the
// "NC" entries below to the reallocated pin name.  The limit is 32
// buttons total.

// LED-Wiz emulation output pin assignments - GPIO mode
//
//   NOTE!  This section isn't used if you have TLC5940 outputs - ALL
//   device outputs will be through the 5940s if you're using them.
//   See the TLC5940 setup section above to configure your interface
//   pins if you're using those chips.
//
// The LED-Wiz protocol allows setting individual intensity levels
// on all outputs, with 48 levels of intensity.  This can be used
// to control lamp brightness and motor speeds, among other things.
// Unfortunately, the KL25Z only has 10 PWM channels, so while we 
// can support the full complement of 32 outputs, we can only provide 
// PWM dimming/speed control on 10 of them.  The remaining outputs 
// can only be switched fully on and fully off - we can't support
// dimming on these, so they'll ignore any intensity level setting 
// requested by the host.  Use these for devices that don't have any
// use for intensity settings anyway, such as contactors and knockers.
//
// Ports with pins assigned as "NC" are not connected.  That is,
// there's no physical pin for that LedWiz port number.  You can
// send LedWiz commands to turn NC ports on and off, but doing so
// will have no effect.  The reason we leave some ports unassigned
// is that we don't have enough physical GPIO pins to fill out the
// full LedWiz complement of 32 ports.  Many pins are already taken
// for other purposes, such as button inputs or the plunger CCD
// interface.
//
// The mapping between physical output pins on the KL25Z and the
// assigned LED-Wiz port numbers is essentially arbitrary - you can
// customize this by changing the entries in the array below if you
// wish to rearrange the pins for any reason.  Be aware that some
// of the physical outputs are already used for other purposes
// (e.g., some of the GPIO pins on header J10 are used for the
// CCD sensor - but you can of course reassign those as well by
// changing the corresponding declarations elsewhere in this module).
// The assignments we make here have two main objectives: first,
// to group the outputs on headers J1 and J2 (to facilitate neater
// wiring by keeping the output pins together physically), and
// second, to make the physical pin layout match the LED-Wiz port
// numbering order to the extent possible.  There's one big wrench
// in the works, though, which is the limited number and discontiguous
// placement of the KL25Z PWM-capable output pins.  This prevents
// us from doing the most obvious sequential ordering of the pins,
// so we end up with the outputs arranged into several blocks.
// Hopefully this isn't too confusing; for more detailed rationale,
// read on...
// 
// With the LED-Wiz, the host software configuration usually 
// assumes that each RGB LED is hooked up to three consecutive ports
// (for the red, green, and blue components, which need to be 
// physically wired to separate outputs to allow each color to be 
// controlled independently).  To facilitate this, we arrange the 
// PWM-enabled outputs so that they're grouped together in the 
// port numbering scheme.  Unfortunately, these outputs aren't
// together in a single group in the physical pin layout, so to
// group them logically in the LED-Wiz port numbering scheme, we
// have to break up the overall numbering scheme into several blocks.
// So our port numbering goes sequentially down each column of
// header pins, but there are several break points where we have
// to interrupt the obvious sequence to keep the PWM pins grouped
// logically.
//
// In the list below, "pin J1-2" refers to pin 2 on header J1 on
// the KL25Z, using the standard pin numbering in the KL25Z 
// documentation - this is the physical pin that the port controls.
// "LW port 1" means LED-Wiz port 1 - this is the LED-Wiz port
// number that you use on the PC side (in the DirectOutput config
// file, for example) to address the port.  PWM-capable ports are
// marked as such - we group the PWM-capable ports into the first
// 10 LED-Wiz port numbers.
//
// If you wish to reallocate a pin in the array below to some other
// use, such as a button input port, simply change the pin name in
// the entry to NC (for Not Connected).  This will disable the given
// logical LedWiz port number and free up the physical pin.
//
// If you wish to reallocate a pin currently assigned to the button
// input array, simply change the entry for the pin in the buttonMap[]
// array above to NC (for "not connected"), and plug the pin name into
// a slot of your choice in the array below.
//
// Note: PTD1 (pin J2-12) should NOT be assigned as an LedWiz output,
// as this pin is physically connected on the KL25Z to the on-board
// indicator LED's blue segment.  This precludes any other use of
