Version 2 of the CERN Open +Hardware Licence comes in three variants: this licence, CERN-OHL-P +(permissive); and two reciprocal licences: CERN- OHL-W (weakly +reciprocal) and CERN-OHL-S (strongly reciprocal). + +The CERN-OHL-P is copyright CERN 2020. Anyone is welcome to use it, in +unmodified form only. + +Use of this Licence does not imply any endorsement by CERN of any +Licensor or their designs nor does it imply any involvement by CERN in +their development. + + +1 Definitions + + 1.1 'Licence' means this CERN-OHL-P. + + 1.2 'Source' means information such as design materials or digital + code which can be applied to Make or test a Product or to + prepare a Product for use, Conveyance or sale, regardless of its + medium or how it is expressed. It may include Notices. + + 1.3 'Covered Source' means Source that is explicitly made available + under this Licence. + + 1.4 'Product' means any device, component, work or physical object, + whether in finished or intermediate form, arising from the use, + application or processing of Covered Source. + + 1.5 'Make' means to create or configure something, whether by + manufacture, assembly, compiling, loading or applying Covered + Source or another Product or otherwise. + + 1.6 'Notice' means copyright, acknowledgement and trademark notices, + references to the location of any Notices, modification notices + (subsection 3.3(b)) and all notices that refer to this Licence + and to the disclaimer of warranties that are included in the + Covered Source. + + 1.7 'Licensee' or 'You' means any person exercising rights under + this Licence. + + 1.8 'Licensor' means a person who creates Source or modifies Covered + Source and subsequently Conveys the resulting Covered Source + under the terms and conditions of this Licence. A person may be + a Licensee and a Licensor at the same time. + + 1.9 'Convey' means to communicate to the public or distribute. + + +2 Applicability + + 2.1 This Licence governs the use, copying, modification, Conveying + of Covered Source and Products, and the Making of Products. By + exercising any right granted under this Licence, You irrevocably + accept these terms and conditions. + + 2.2 This Licence is granted by the Licensor directly to You, and + shall apply worldwide and without limitation in time. + + 2.3 You shall not attempt to restrict by contract or otherwise the + rights granted under this Licence to other Licensees. + + 2.4 This Licence is not intended to restrict fair use, fair dealing, + or any other similar right. + + +3 Copying, modifying and Conveying Covered Source + + 3.1 You may copy and Convey verbatim copies of Covered Source, in + any medium, provided You retain all Notices. + + 3.2 You may modify Covered Source, other than Notices. + + You may only delete Notices if they are no longer applicable to + the corresponding Covered Source as modified by You and You may + add additional Notices applicable to Your modifications. + + 3.3 You may Convey modified Covered Source (with the effect that You + shall also become a Licensor) provided that You: + + a) retain Notices as required in subsection 3.2; and + + b) add a Notice to the modified Covered Source stating that You + have modified it, with the date and brief description of how + You have modified it. + + 3.4 You may Convey Covered Source or modified Covered Source under + licence terms which differ from the terms of this Licence + provided that: + + a) You comply at all times with subsection 3.3; and + + b) You provide a copy of this Licence to anyone to whom You + Convey Covered Source or modified Covered Source. + + +4 Making and Conveying Products + +You may Make Products, and/or Convey them, provided that You ensure +that the recipient of the Product has access to any Notices applicable +to the Product. + + +5 DISCLAIMER AND LIABILITY + + 5.1 DISCLAIMER OF WARRANTY -- The Covered Source and any Products + are provided 'as is' and any express or implied warranties, + including, but not limited to, implied warranties of + merchantability, of satisfactory quality, non-infringement of + third party rights, and fitness for a particular purpose or use + are disclaimed in respect of any Source or Product to the + maximum extent permitted by law. The Licensor makes no + representation that any Source or Product does not or will not + infringe any patent, copyright, trade secret or other + proprietary right. The entire risk as to the use, quality, and + performance of any Source or Product shall be with You and not + the Licensor. This disclaimer of warranty is an essential part + of this Licence and a condition for the grant of any rights + granted under this Licence. + + 5.2 EXCLUSION AND LIMITATION OF LIABILITY -- The Licensor shall, to + the maximum extent permitted by law, have no liability for + direct, indirect, special, incidental, consequential, exemplary, + punitive or other damages of any character including, without + limitation, procurement of substitute goods or services, loss of + use, data or profits, or business interruption, however caused + and on any theory of contract, warranty, tort (including + negligence), product liability or otherwise, arising in any way + in relation to the Covered Source, modified Covered Source + and/or the Making or Conveyance of a Product, even if advised of + the possibility of such damages, and You shall hold the + Licensor(s) free and harmless from any liability, costs, + damages, fees and expenses, including claims by third parties, + in relation to such use. + + +6 Patents + + 6.1 Subject to the terms and conditions of this Licence, each + Licensor hereby grants to You a perpetual, worldwide, + non-exclusive, no-charge, royalty-free, irrevocable (except as + stated in this section 6, or where terminated by the Licensor + for cause) patent license to Make, have Made, use, offer to + sell, sell, import, and otherwise transfer the Covered Source + and Products, where such licence applies only to those patent + claims licensable by such Licensor that are necessarily + infringed by exercising rights under the Covered Source as + Conveyed by that Licensor. + + 6.2 If You institute patent litigation against any entity (including + a cross-claim or counterclaim in a lawsuit) alleging that the + Covered Source or a Product constitutes direct or contributory + patent infringement, or You seek any declaration that a patent + licensed to You under this Licence is invalid or unenforceable + then any rights granted to You under this Licence shall + terminate as of the date such process is initiated. + + +7 General + + 7.1 If any provisions of this Licence are or subsequently become + invalid or unenforceable for any reason, the remaining + provisions shall remain effective. + + 7.2 You shall not use any of the name (including acronyms and + abbreviations), image, or logo by which the Licensor or CERN is + known, except where needed to comply with section 3, or where + the use is otherwise allowed by law.

New + versions will be published with a unique version number and a + variant identifier specifying the variant. If the Licensor has + specified that a given variant applies to the Covered Source + without specifying a version, You may treat that Covered Source + as being released under any version of the CERN-OHL with that + variant. If no variant is specified, the Covered Source shall be + treated as being released under CERN-OHL-S. The Licensor may + also specify that the Covered Source is subject to a specific + version of the CERN-OHL or any later version in which case You + may apply this or any later version of CERN-OHL with the same + variant identifier published by CERN. + + 7.4 This Licence shall not be enforceable except by a Licensor + acting as such, and third party beneficiary rights are + specifically excluded. diff --git a/sw/demo1/src/main.rs b/sw/demo1/src/main.rs index 093df4f..3f98295 100644 --- a/sw/demo1/src/main.rs +++ b/sw/demo1/src/main.rs @@ -1,3 +1,27 @@ +/* + The MIT License (MIT) + + Copyright (c) 2020 Matthias P.
