We ask that you don’t just aim to be 54 | "technically unimpeachable", but rather try to be your best self. 55 | 56 | We value many things beyond technical expertise, including collaboration and 57 | supporting others within our community. Providing a positive experience for 58 | other community members can have a much more significant impact than simply 59 | providing the correct answer. 60 | 61 | ## Our Responsibilities 62 | 63 | Project leaders are responsible for clarifying the standards of acceptable 64 | behavior and are expected to take appropriate and fair corrective action in 65 | response to any instances of unacceptable behavior. 66 | 67 | Project leaders have the right and responsibility to remove, edit, or 68 | reject messages, comments, commits, code, issues, and other contributions 69 | that are not aligned to this Code of Conduct, or to ban temporarily or 70 | permanently any community member for other behaviors that they deem 71 | inappropriate, threatening, offensive, or harmful. 72 | 73 | ## Moderation 74 | 75 | Instances of behaviors that violate the CircuitPython Community Code of Conduct 76 | may be reported by any member of the community. Community members are 77 | encouraged to report these situations, including situations they witness 78 | involving other community members. 79 | 80 | You may report in the following ways: 81 | 82 | In any situation, you may email the project maintainer. 83 | 84 | Email reports will be kept confidential. 85 | 86 | In situations on GitHub where the issue is particularly offensive, possibly 87 | illegal, requires immediate action, or violates the GitHub terms of service, 88 | you should also report the message directly to GitHub via the comment, or via 89 | [GitHub Support](https://support.github.com/contact/report-abuse?category=report-abuse&report=other&report_type=unspecified). 90 | 91 | These are the steps for upholding our community’s standards of conduct. 92 | 93 | 1. Any member of the community may report any situation that violates the 94 | CircuitPython Community Code of Conduct. All reports will be reviewed and 95 | investigated. 96 | 2. If the behavior is a severe violation, the community member who 97 | committed the violation may be banned immediately, without warning. 98 | 3. Otherwise, moderators will first respond to such behavior with a warning. 99 | 4. Moderators follow a soft "three strikes" policy - the community member may 100 | be given another chance, if they are receptive to the warning and change their 101 | behavior. 102 | 5. If the community member is unreceptive or unreasonable when warned by a 103 | moderator, or the warning goes unheeded, they may be banned for a first or 104 | second offense. Repeated offenses will result in the community member being 105 | banned. 106 | 6. Disciplinary actions (warnings, bans, etc) for Code of Conduct violations apply 107 | to the platform where the violation occurred. However, depending on the severity 108 | of the violation, the disciplinary action may be applied across CircuitPython's 109 | other community platforms. For example, a severe violation in one Community forum 110 | may result in a ban on not only the CircuitPython GitHub organisation, 111 | but also on the CircuitPython Twitter, live stream text chats, etc. 112 | 113 | ## Scope 114 | 115 | This Code of Conduct and the enforcement policies listed above apply to all 116 | CircuitPython Community venues. This includes but is not limited to any community 117 | spaces (both public and private), and CircuitPython repositories. Examples of 118 | CircuitPython Community spaces include but are not limited to meet-ups, issue 119 | threads on GitHub, text chats during a live stream, or interaction at a conference. 120 | 121 | This Code of Conduct applies both within project spaces and in public spaces 122 | when an individual is representing the project or its community. As a community 123 | member, you are representing our community, and are expected to behave 124 | accordingly. 125 | 126 | ## Attribution 127 | 128 | This Code of Conduct is adapted from the 129 | [Adafruit Community Code of Conduct](https://github.com/adafruit/Adafruit_Community_Code_of_Conduct), 130 | which is adapted from the [Contributor Covenant](https://www.contributor-covenant.org/), 131 | version 1.4, available on [contributor-covenant.org](https://www.contributor-covenant.org/version/1/4/code-of-conduct.html), 132 | and the [Rust Code of Conduct](https://www.rust-lang.org/en-US/conduct.html). 133 | 134 | For other projects adopting the CircuitPython Community Code of 135 | Conduct, please contact the maintainers of those projects for enforcement. 136 | If you wish to use this code of conduct for your own project, consider 137 | explicitly mentioning your moderation policy or making a copy with your 138 | own moderation policy so as to avoid confusion. 139 | -------------------------------------------------------------------------------- /LICENSE: -------------------------------------------------------------------------------- 1 | The MIT License (MIT) 2 | 3 | Copyright (c) 2023 Seth Kerr for Oak Development Technologies 4 | 5 | Permission is hereby granted, free of charge, to any person obtaining a copy 6 | of this software and associated documentation files (the "Software"), to deal 7 | in the Software without restriction, including without limitation the rights 8 | to use, copy, modify, merge, publish, distribute, sublicense, and/or sell 9 | copies of the Software, and to permit persons to whom the Software is 10 | furnished to do so, subject to the following conditions: 11 | 12 | The above copyright notice and this permission notice shall be included in all 13 | copies or substantial portions of the Software. 14 | 15 | THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR 16 | IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, 17 | FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

The following considerations are for 16 | informational purposes only, are not exhaustive, and do not form part of our 17 | licenses. 18 | 19 | Considerations for licensors: Our public licenses are intended for use by 20 | those authorized to give the public permission to use material in ways otherwise 21 | restricted by copyright and certain other rights. Our licenses are irrevocable. 22 | Licensors should read and understand the terms and conditions of the license 23 | they choose before applying it. Licensors should also secure all rights necessary 24 | before applying our licenses so that the public can reuse the material as 25 | expected. Licensors should clearly mark any material not subject to the license. 26 | This includes other CC-licensed material, or material used under an exception 27 | or limitation to copyright. More considerations for licensors : wiki.creativecommons.org/Considerations_for_licensors 28 | 29 | Considerations for the public: By using one of our public licenses, a licensor 30 | grants the public permission to use the licensed material under specified 31 | terms and conditions. If the licensor's permission is not necessary for any 32 | reason–for example, because of any applicable exception or limitation to copyright–then 33 | that use is not regulated by the license. Our licenses grant only permissions 34 | under copyright and certain other rights that a licensor has authority to 35 | grant. Use of the licensed material may still be restricted for other reasons, 36 | including because others have copyright or other rights in the material. A 37 | licensor may make special requests, such as asking that all changes be marked 38 | or described. Although not required by our licenses, you are encouraged to 39 | respect those requests where reasonable. More considerations for the public 40 | : wiki.creativecommons.org/Considerations_for_licensees Creative Commons Attribution 41 | 4.0 International Public License 42 | 43 | By exercising the Licensed Rights (defined below), You accept and agree to 44 | be bound by the terms and conditions of this Creative Commons Attribution 45 | 4.0 International Public License ("Public License"). To the extent this Public 46 | License may be interpreted as a contract, You are granted the Licensed Rights 47 | in consideration of Your acceptance of these terms and conditions, and the 48 | Licensor grants You such rights in consideration of benefits the Licensor 49 | receives from making the Licensed Material available under these terms and 50 | conditions. 51 | 52 | Section 1 – Definitions. 53 | 54 | a. Adapted Material means material subject to Copyright and Similar Rights 55 | that is derived from or based upon the Licensed Material and in which the 56 | Licensed Material is translated, altered, arranged, transformed, or otherwise 57 | modified in a manner requiring permission under the Copyright and Similar 58 | Rights held by the Licensor. For purposes of this Public License, where the 59 | Licensed Material is a musical work, performance, or sound recording, Adapted 60 | Material is always produced where the Licensed Material is synched in timed 61 | relation with a moving image. 62 | 63 | b. Adapter's License means the license You apply to Your Copyright and Similar 64 | Rights in Your contributions to Adapted Material in accordance with the terms 65 | and conditions of this Public License. 66 | 67 | c. Copyright and Similar Rights means copyright and/or similar rights closely 68 | related to copyright including, without limitation, performance, broadcast, 69 | sound recording, and Sui Generis Database Rights, without regard to how the 70 | rights are labeled or categorized. For purposes of this Public License, the 71 | rights specified in Section 2(b)(1)-(2) are not Copyright and Similar Rights. 72 | 73 | d. Effective Technological Measures means those measures that, in the absence 74 | of proper authority, may not be circumvented under laws fulfilling obligations 75 | under Article 11 of the WIPO Copyright Treaty adopted on December 20, 1996, 76 | and/or similar international agreements. 77 | 78 | e.

Licensed Rights means the rights granted to You subject to the terms and 86 | conditions of this Public License, which are limited to all Copyright and 87 | Similar Rights that apply to Your use of the Licensed Material and that the 88 | Licensor has authority to license. 89 | 90 | h. Licensor means the individual(s) or entity(ies) granting rights under this 91 | Public License. 92 | 93 | i. Share means to provide material to the public by any means or process that 94 | requires permission under the Licensed Rights, such as reproduction, public 95 | display, public performance, distribution, dissemination, communication, or 96 | importation, and to make material available to the public including in ways 97 | that members of the public may access the material from a place and at a time 98 | individually chosen by them. 99 | 100 | j. Sui Generis Database Rights means rights other than copyright resulting 101 | from Directive 96/9/EC of the European Parliament and of the Council of 11 102 | March 1996 on the legal protection of databases, as amended and/or succeeded, 103 | as well as other essentially equivalent rights anywhere in the world. 104 | 105 | k. You means the individual or entity exercising the Licensed Rights under 106 | this Public License. Your has a corresponding meaning. 107 | 108 | Section 2 – Scope. 109 | 110 | a. License grant. 111 | 112 | 1. Subject to the terms and conditions of this Public License, the Licensor 113 | hereby grants You a worldwide, royalty-free, non-sublicensable, non-exclusive, 114 | irrevocable license to exercise the Licensed Rights in the Licensed Material 115 | to: 116 | 117 | A. reproduce and Share the Licensed Material, in whole or in part; and 118 | 119 | B. produce, reproduce, and Share Adapted Material. 120 | 121 | 2. Exceptions and Limitations. For the avoidance of doubt, where Exceptions 122 | and Limitations apply to Your use, this Public License does not apply, and 123 | You do not need to comply with its terms and conditions. 124 | 125 | 3. Term. The term of this Public License is specified in Section 6(a). 126 | 127 | 4. Media and formats; technical modifications allowed. The Licensor authorizes 128 | You to exercise the Licensed Rights in all media and formats whether now known 129 | or hereafter created, and to make technical modifications necessary to do 130 | so. The Licensor waives and/or agrees not to assert any right or authority 131 | to forbid You from making technical modifications necessary to exercise the 132 | Licensed Rights, including technical modifications necessary to circumvent 133 | Effective Technological Measures. For purposes of this Public License, simply 134 | making modifications authorized by this Section 2(a)(4) never produces Adapted 135 | Material. 136 | 137 | 5. Downstream recipients. 138 | 139 | A. Offer from the Licensor – Licensed Material. Every recipient of the Licensed 140 | Material automatically receives an offer from the Licensor to exercise the 141 | Licensed Rights under the terms and conditions of this Public License. 142 | 143 | B. No downstream restrictions. You may not offer or impose any additional 144 | or different terms or conditions on, or apply any Effective Technological 145 | Measures to, the Licensed Material if doing so restricts exercise of the Licensed 146 | Rights by any recipient of the Licensed Material. 147 | 148 | 6. No endorsement. Nothing in this Public License constitutes or may be construed 149 | as permission to assert or imply that You are, or that Your use of the Licensed 150 | Material is, connected with, or sponsored, endorsed, or granted official status 151 | by, the Licensor or others designated to receive attribution as provided in 152 | Section 3(a)(1)(A)(i). 153 | 154 | b. Other rights. 155 | 156 | 1. Moral rights, such as the right of integrity, are not licensed under this 157 | Public License, nor are publicity, privacy, and/or other similar personality 158 | rights; however, to the extent possible, the Licensor waives and/or agrees 159 | not to assert any such rights held by the Licensor to the limited extent necessary 160 | to allow You to exercise the Licensed Rights, but not otherwise. 161 | 162 | 2. Patent and trademark rights are not licensed under this Public License. 163 | 164 | 3. To the extent possible, the Licensor waives any right to collect royalties 165 | from You for the exercise of the Licensed Rights, whether directly or through 166 | a collecting society under any voluntary or waivable statutory or compulsory 167 | licensing scheme. In all other cases the Licensor expressly reserves any right 168 | to collect such royalties. 169 | 170 | Section 3 – License Conditions. 171 | 172 | Your exercise of the Licensed Rights is expressly made subject to the following 173 | conditions. 174 | 175 | a. Attribution. 176 | 177 | 1. If You Share the Licensed Material (including in modified form), You must: 178 | 179 | A. retain the following if it is supplied by the Licensor with the Licensed 180 | Material: 181 | 182 | i. identification of the creator(s) of the Licensed Material and any others 183 | designated to receive attribution, in any reasonable manner requested by the 184 | Licensor (including by pseudonym if designated); 185 | 186 | ii. a copyright notice; 187 | 188 | iii. a notice that refers to this Public License; 189 | 190 | iv. a notice that refers to the disclaimer of warranties; 191 | 192 | v. a URI or hyperlink to the Licensed Material to the extent reasonably practicable; 193 | 194 | B. indicate if You modified the Licensed Material and retain an indication 195 | of any previous modifications; and 196 | 197 | C. indicate the Licensed Material is licensed under this Public License, and 198 | include the text of, or the URI or hyperlink to, this Public License. 199 | 200 | 2. You may satisfy the conditions in Section 3(a)(1) in any reasonable manner 201 | based on the medium, means, and context in which You Share the Licensed Material. 202 | For example, it may be reasonable to satisfy the conditions by providing a 203 | URI or hyperlink to a resource that includes the required information. 204 | 205 | 3. If requested by the Licensor, You must remove any of the information required 206 | by Section 3(a)(1)(A) to the extent reasonably practicable. 207 | 208 | 4. If You Share Adapted Material You produce, the Adapter's License You apply 209 | must not prevent recipients of the Adapted Material from complying with this 210 | Public License. 211 | 212 | Section 4 – Sui Generis Database Rights. 213 | 214 | Where the Licensed Rights include Sui Generis Database Rights that apply to 215 | Your use of the Licensed Material: 216 | 217 | a. for the avoidance of doubt, Section 2(a)(1) grants You the right to extract, 218 | reuse, reproduce, and Share all or a substantial portion of the contents of 219 | the database; 220 | 221 | b. if You include all or a substantial portion of the database contents in 222 | a database in which You have Sui Generis Database Rights, then the database 223 | in which You have Sui Generis Database Rights (but not its individual contents) 224 | is Adapted Material; and 225 | 226 | c. You must comply with the conditions in Section 3(a) if You Share all or 227 | a substantial portion of the contents of the database. 228 | 229 | For the avoidance of doubt, this Section 4 supplements and does not replace 230 | Your obligations under this Public License where the Licensed Rights include 231 | other Copyright and Similar Rights. 232 | 233 | Section 5 – Disclaimer of Warranties and Limitation of Liability. 234 | 235 | a. Unless otherwise separately undertaken by the Licensor, to the extent possible, 236 | the Licensor offers the Licensed Material as-is and as-available, and makes 237 | no representations or warranties of any kind concerning the Licensed Material, 238 | whether express, implied, statutory, or other. This includes, without limitation, 239 | warranties of title, merchantability, fitness for a particular purpose, non-infringement, 240 | absence of latent or other defects, accuracy, or the presence or absence of 241 | errors, whether or not known or discoverable. Where disclaimers of warranties 242 | are not allowed in full or in part, this disclaimer may not apply to You. 243 | 244 | b. To the extent possible, in no event will the Licensor be liable to You 245 | on any legal theory (including, without limitation, negligence) or otherwise 246 | for any direct, special, indirect, incidental, consequential, punitive, exemplary, 247 | or other losses, costs, expenses, or damages arising out of this Public License 248 | or use of the Licensed Material, even if the Licensor has been advised of 249 | the possibility of such losses, costs, expenses, or damages. Where a limitation 250 | of liability is not allowed in full or in part, this limitation may not apply 251 | to You. 252 | 253 | c. The disclaimer of warranties and limitation of liability provided above 254 | shall be interpreted in a manner that, to the extent possible, most closely 255 | approximates an absolute disclaimer and waiver of all liability. 256 | 257 | Section 6 – Term and Termination. 258 | 259 | a. This Public License applies for the term of the Copyright and Similar Rights 260 | licensed here. However, if You fail to comply with this Public License, then 261 | Your rights under this Public License terminate automatically. 262 | 263 | b. Where Your right to use the Licensed Material has terminated under Section 264 | 6(a), it reinstates: 265 | 266 | 1. automatically as of the date the violation is cured, provided it is cured 267 | within 30 days of Your discovery of the violation; or 268 | 269 | 2. upon express reinstatement by the Licensor. 270 | 271 | c. For the avoidance of doubt, this Section 6(b) does not affect any right 272 | the Licensor may have to seek remedies for Your violations of this Public 273 | License. 274 | 275 | d. For the avoidance of doubt, the Licensor may also offer the Licensed Material 276 | under separate terms or conditions or stop distributing the Licensed Material 277 | at any time; however, doing so will not terminate this Public License. 278 | 279 | e. Sections 1, 5, 6, 7, and 8 survive termination of this Public License. 280 | 281 | Section 7 – Other Terms and Conditions. 282 | 283 | a. The Licensor shall not be bound by any additional or different terms or 284 | conditions communicated by You unless expressly agreed. 285 | 286 | b. Any arrangements, understandings, or agreements regarding the Licensed 287 | Material not stated herein are separate from and independent of the terms 288 | and conditions of this Public License. 289 | 290 | Section 8 – Interpretation. 291 | 292 | a. For the avoidance of doubt, this Public License does not, and shall not 293 | be interpreted to, reduce, limit, restrict, or impose conditions on any use 294 | of the Licensed Material that could lawfully be made without permission under 295 | this Public License. 296 | 297 | b. To the extent possible, if any provision of this Public License is deemed 298 | unenforceable, it shall be automatically reformed to the minimum extent necessary 299 | to make it enforceable. If the provision cannot be reformed, it shall be severed 300 | from this Public License without affecting the enforceability of the remaining 301 | terms and conditions. 302 | 303 | c. No term or condition of this Public License will be waived and no failure 304 | to comply consented to unless expressly agreed to by the Licensor. 305 | 306 | d. Nothing in this Public License constitutes or may be interpreted as a limitation 307 | upon, or waiver of, any privileges and immunities that apply to the Licensor 308 | or You, including from the legal processes of any jurisdiction or authority. 309 | 310 | Creative Commons is not a party to its public licenses.

Calling `program_fpga()` then 25 | programs the FPGA with the bin file provided. Be sure to include all the required dependencies.
