mjr 35:e959ffba78fd 1 // USB Message Protocol
mjr 35:e959ffba78fd 2 //
mjr 74:822a92bc11d2 3 // This file is purely for documentation, to describe our USB protocol
mjr 74:822a92bc11d2 4 // for incoming messages (host to device). We use the standard HID setup
mjr 74:822a92bc11d2 5 // with one endpoint in each direction. See USBJoystick.cpp and .h for
mjr 74:822a92bc11d2 6 // the USB descriptors.
mjr 74:822a92bc11d2 7 //
mjr 74:822a92bc11d2 8 // Our incoming message protocol is an extended version of the protocol
mjr 74:822a92bc11d2 9 // used by the LedWiz. Our protocol is designed to be 100% backwards
mjr 74:822a92bc11d2 10 // compatible with clients using the original LedWiz wire protocol, as long
mjr 74:822a92bc11d2 11 // as they only send well-formed messages in the original protocol. The
mjr 74:822a92bc11d2 12 // "well-formed" part is an important condition, because our extensions to
mjr 74:822a92bc11d2 13 // the original protocol all consist of messages that aren't defined in the
mjr 74:822a92bc11d2 14 // original protocol and are meaningless to a real LedWiz.
mjr 35:e959ffba78fd 15 //
mjr 74:822a92bc11d2 16 // The protocol compatibility ensures that all original LedWiz clients can
mjr 74:822a92bc11d2 17 // also transparently access a Pinscape unit. Clients will simply think the
mjr 74:822a92bc11d2 18 // Pinscape unit is an LedWiz, thus they'll be able to operate 32 of our
mjr 74:822a92bc11d2 19 // ports. We designate the first 32 ports (ports 1-32) as the ones accessible
mjr 74:822a92bc11d2 20 // through the LedWiz protocol.
mjr 74:822a92bc11d2 21 //
mjr 74:822a92bc11d2 22 // In addition the wire-level protocol compatibility, we can provide legacy
mjr 74:822a92bc11d2 23 // LedWiz clients with access to more than 32 ports by emulating multiple
mjr 74:822a92bc11d2 24 // virtual LedWiz units. We can't do this across the wire protocol, since
mjr 74:822a92bc11d2 25 // the KL25Z USB interface constrains us to a single VID/PID (which is how
mjr 74:822a92bc11d2 26 // LedWiz clients distinguish units). However, virtuall all legacy LedWiz
mjr 74:822a92bc11d2 27 // clients access the device through a shared library, LEDWIZ.DLL, rather
mjr 74:822a92bc11d2 28 // than directly through USB. LEDWIZ.DLL is distributed by the LedWiz's
mjr 74:822a92bc11d2 29 // manufacturer and has a published client interface. We can thus provide
mjr 74:822a92bc11d2 30 // a replacement DLL that contains the logic needed to recognize a Pinscape
mjr 74:822a92bc11d2 31 // unit and represent it to clients as multiple LedWiz devices. This allows
mjr 74:822a92bc11d2 32 // old clients to access our full complement of ports without any changes
mjr 74:822a92bc11d2 33 // to the clients. We define some extended message types (SBX and PBX)
mjr 74:822a92bc11d2 34 // specifically to support this DLL feature.

mjr 77:0b96f6867312 351 // WHY WE USE A HACKY APPROACH TO DIFFERENT REPORT TYPES
mjr 35:e959ffba78fd 352 //
mjr 35:e959ffba78fd 353 // The HID report system was specifically designed to provide a clean,
mjr 35:e959ffba78fd 354 // structured way for devices to describe the data they send to the host.
mjr 35:e959ffba78fd 355 // Our approach isn't clean or structured; it ignores the promises we
mjr 35:e959ffba78fd 356 // make about the contents of our report via the HID Report Descriptor
mjr 35:e959ffba78fd 357 // and stuffs our own different data format into the same structure.
mjr 35:e959ffba78fd 358 //
mjr 77:0b96f6867312 359 // We use this hacky approach only because we can't use the standard USB
mjr 77:0b96f6867312 360 // HID mechanism for varying report types, which is to provide multiple
mjr 77:0b96f6867312 361 // report descriptors and tag each report with a type byte that indicates
mjr 77:0b96f6867312 362 // which descriptor applies. We can't use that standard approach because
mjr 77:0b96f6867312 363 // we want to be 100% LedWiz compatible. The snag is that some Windows
mjr 77:0b96f6867312 364 // LedWiz clients parse the USB HID descriptors as part of identifying a
mjr 77:0b96f6867312 365 // USB HID device as a valid LedWiz unit, and will only recognize the device
mjr 77:0b96f6867312 366 // if certain properties of the HID descriptors match those of a real LedWiz.
mjr 77:0b96f6867312 367 // One of the features that's important to some clients is the descriptor
mjr 77:0b96f6867312 368 // link structure, which is affected by the layout of HID Report Descriptor
mjr 77:0b96f6867312 369 // entries. In order to match the expected layout, we can only define a
mjr 77:0b96f6867312 370 // single kind of output report. Since we have to use Joystick reports for

mjr 77:0b96f6867312 374 // hack, but at least it's a fairly reliable and isolated hack, in that our
