// 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

// USB device vendor ID and product ID.  These values identify the device 
// to the host software on the PC.  By default, we use the same settings as
// a real LedWiz so that host software will recognize us as an LedWiz.
//
// The standard settings *should* work without conflicts, even if you have 
// a real LedWiz.  My reference system is 64-bit Windows 7 with a real LedWiz 
// on unit #1 and a Pinscape controller on unit #8 (the default), and the 
// two coexist happily in my system.  The LedWiz is designed specifically 
// to allow multiple units in one system, using the unit number value 
// (see below) to distinguish multiple units, so there should be no conflict
// between Pinscape and any real LedWiz devices you have.
//
// However, even though conflicts *shouldn't* happen, I've had one report
// from a user who experienced a Windows USB driver conflict that they could
// only resolve by changing the vendor ID.  The real underlying cause is 
// still a mystery, but whatever was going on, changing the vendor ID fixed 
// it.  If you run into a similar problem, you can try the same fix as a
// last resort.  Before doing that, though, you should try changing the 
// Pinscape unit number first - it's possible that your real LedWiz is using 
// unit #8, which is our default setting.
//
// If you must change the vendor ID for any reason, you'll sacrifice LedWiz
// compatibility, which means that old programs like Future Pinball that use
// the LedWiz interface directly won't be able to access the LedWiz output
// controller features.  However, all is not lost.  All of the other functions
// (plunger, nudge, and key input) use the joystick interface, which will 
// work regardless of the ID values.  In addition, DOF R3 recognizes the
// "emergency fallback" ID below, so if you use that, *all* functions
// including the output controller will work in any DOF R3-enabled software,
// including Visual Pinball and PinballX.  So the only loss will be that
// old LedWiz-only software won't be able to control the outputs.
//
// The "emergency fallback" ID below is officially registerd with 
// http://pid.codes, a registry for open-source USB projects, which should 
// all but guarantee that this alternative ID shouldn't conflict with 
// any other devices in your system.

// LedWiz 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.  If you don't tell
// them otherwise when placing your order, they will set it to unit #1.  Most
// real LedWiz units therefore are set to unit #1.  There's no provision on
// a real LedWiz for users to change the unit number after it leaves the 
// factory.
//
// For our *emulated* LedWiz, we default to unit #8 if we're the primary
// Pinscape controller in the system, or unit #9 if we're set up as the
// secondary controller with the joystick functions turned off.
//
// The reason we start at unit #8 is that we want to avoid conflicting with
// any real LedWiz devices in your system.  Most real LedWiz devices are
// set up as unit #1, and in the rare cases where people have two of them,
// the second one is usually unit #2.  
//
// 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.

// Accelerometer orientation.  The accelerometer feature lets Visual Pinball 
// (and other pinball software) sense nudges to the cabinet, and simulate

// for VP and the KL25Z to agree on the physical orientation of the

// 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

// 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.  Visual Pinball
// only polls for input at about 10ms intervals, so there's no benefit
// to going much faster than this.  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

// 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.

// 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

// 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 when using the TLC5940, you can still also use some GPIO
// pins for outputs as normal.  See ledWizPinMap[] for 

// Number of TLC5940 chips you're using.  For a full LedWiz-compatible
// setup, you need two of these chips, for 32 outputs.  The software
// will handle up to 8.

// Joystick button input pin assignments.  
//
// You can wire up to 32 GPIO ports to buttons (equipped with 
// momentary switches).  Connect each switch between the desired

// we'll tell the host PC that the corresponding joystick button is

// 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.
//
// (If you're using TLC5940 chips to control outputs, many of the

// LED-Wiz emulation output pin assignments
//
// This sets the mapping from logical LedWiz port numbers, as used
// in the software on the PC side, to physical hardware pins on the
// KL25Z and/or the TLC5940 controllers.
//
// The LedWiz protocol lets the PC software set a "brightness" level
// for each output.  This is used to control the intensity of LEDs
// and other lights, and can also control motor speeds.  To implement 
// the intensity level in hardware, we use PWM, or pulse width
// modulation, which switches the output on and off very rapidly
// to give the effect of a reduced voltage.  Unfortunately, the KL25Z
// hardware is limited to 10 channels of PWM control for its GPIO
// outputs, so it's impossible to implement the LedWiz's full set
// of 32 adjustable outputs using only GPIO ports.  However, you can
// create 10 adjustable ports and fill out the rest with "digital"
// GPIO pins, which are simple on/off switches.  The intensity level
// of a digital port can't be adjusted - it's either fully on or
// fully off - but this is fine for devices that don't have
// different intensity settings anyway, such as replay knockers
// and flipper solenoids.
//
// In the mapping list below, you can decide how to dole out the
// PWM-capable and digital-only GPIO pins.  To make it easier to
// remember which is which, the default mapping below groups all
// of the PWM-capable ports together in the first 10 logical LedWiz
// port numbers.  Unfortunately, these ports aren't *physically*
// together on the KL25Z pin headers, so this layout may be simple
// in terms of the LedWiz numbering, but it's a little jumbled
// in the physical layout.t
//
// "NC" in the pin name slot means "not connected".  This means
// that there's no physical output for this LedWiz port number.
// The device will still accept commands that control the port,
// but these will just be silently ignored, since there's no pin
// to turn on or off for these ports.  The reason we leave some 
// ports unconnected 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 file).
// 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: Don't assign PTD1 (pin J2-12) as an LedWiz output.  That pin
// is hard-wired on the KL25Z to the on-board indicator LED's blue segment,  
// which pretty precludes other uses of the pin.
//
// ACTIVE-LOW PORTS:  By default, when a logical port is turned on in
// the software, we set the physical GPIO voltage to "high" (3.3V), and
// set it "low" (0V) when the logical port is off.  This is the right
// scheme for the booster circuit described in the build guide.  Some
// third-party booster circuits want the opposite voltage scheme, where
// logical "on" is represented by 0V on the port and logical "off" is
// represented by 3.3V.  If you're using an "active low" booster like
// that, set the PORT_ACTIVE_LOW flag in the array below for each 
// affected port.
//
// TLC5940 PORTS:  To assign an LedWiz output port number to a particular
// output on a TLC5940, set the port type to TLC_PORT and set the 'pin'
// value to the index of the output port in the daisy chain.  The first
// chip in the daisy chain has ports 1-16, the second has ports 17-32, 
// and so on.
//
// 74HC595 PORTS:  To assign an LedWiz output port to a 74HC595 port,
// set the port type to HC595_PORT and set 'pin' to the index of the port
// in the daisy chain.  The first chip has ports 1-8, the second has 
// 9-16, etc.
