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 | 35:e959ffba78fd | 47 | // using in-the-box drivers. This allows a completely transparent, driverless, |

mjr | 77:0b96f6867312 | 388 | // We use this hacky approach only because we can't use the standard USB |

mjr | 77:0b96f6867312 | 393 | // LedWiz clients parse the USB HID descriptors as part of identifying a |

mjr | 35:e959ffba78fd | 733 | // is with the SBA/PBA messages. To turn an output OFF with this message, set |
mjr | 35:e959ffba78fd | 734 | // the intensity to 0. Setting a non-zero intensity turns it on immediately |
mjr | 35:e959ffba78fd | 735 | // without regard to the SBA status for the port. Second, the brightness is |
mjr | 35:e959ffba78fd | 736 | // on a full 8-bit scale (0-255) rather than the LedWiz's approximately 5-bit |
mjr | 35:e959ffba78fd | 737 | // scale, because there are no parts of the range reserved for flashing modes. |
mjr | 35:e959ffba78fd | 738 | // |
mjr | 35:e959ffba78fd | 739 | // Outputs 1-32 can be controlled by EITHER the regular LedWiz SBA/PBA messages |
mjr | 35:e959ffba78fd | 740 | // or by the extended messages. The latest setting for a given port takes |
mjr | 35:e959ffba78fd | 741 | // precedence. If an SBA/PBA message was the last thing sent to a port, the |
mjr | 35:e959ffba78fd | 742 | // normal LedWiz combination of ON/OFF and brightness/flash mode status is used |
mjr | 35:e959ffba78fd | 743 | // to determine the port's physical output setting. If an extended brightness |
mjr | 35:e959ffba78fd | 744 | // message was the last thing sent to a port, the LedWiz ON/OFF status and |
mjr | 35:e959ffba78fd | 745 | // flash modes are ignored, and the fixed brightness is set. Outputs 33 and |
mjr | 35:e959ffba78fd | 746 | // higher inherently can't be addressed or affected by SBA/PBA messages. |
