We ask that you don’t just aim to be 52 | "technically unimpeachable", but rather try to be your best self. 53 | 54 | We value many things beyond technical expertise, including collaboration and 55 | supporting others within our community. Providing a positive experience for 56 | other community members can have a much more significant impact than simply 57 | providing the correct answer. 58 | 59 | ## Our Responsibilities 60 | 61 | Project leaders are responsible for clarifying the standards of acceptable 62 | behavior and are expected to take appropriate and fair corrective action in 63 | response to any instances of unacceptable behavior. 64 | 65 | Project leaders have the right and responsibility to remove, edit, or 66 | reject messages, comments, commits, code, issues, and other contributions 67 | that are not aligned to this Code of Conduct, or to ban temporarily or 68 | permanently any community member for other behaviors that they deem 69 | inappropriate, threatening, offensive, or harmful. 70 | 71 | ## Moderation 72 | 73 | Instances of behaviors that violate the Adafruit Community Code of Conduct 74 | may be reported by any member of the community. Community members are 75 | encouraged to report these situations, including situations they witness 76 | involving other community members. 77 | 78 | You may report in the following ways: 79 | 80 | In any situation, you may send an email to . 81 | 82 | On the Adafruit Discord, you may send an open message from any channel 83 | to all Community Moderators by tagging @community moderators. You may 84 | also send an open message from any channel, or a direct message to 85 | @kattni#1507, @tannewt#4653, @Dan Halbert#1614, @cater#2442, 86 | @sommersoft#0222, @Mr. Certainly#0472 or @Andon#8175. 87 | 88 | Email and direct message reports will be kept confidential. 89 | 90 | In situations on Discord where the issue is particularly egregious, possibly 91 | illegal, requires immediate action, or violates the Discord terms of service, 92 | you should also report the message directly to Discord. 93 | 94 | These are the steps for upholding our community’s standards of conduct. 95 | 96 | 1. Any member of the community may report any situation that violates the 97 | Adafruit Community Code of Conduct. All reports will be reviewed and 98 | investigated. 99 | 2. If the behavior is an egregious violation, the community member who 100 | committed the violation may be banned immediately, without warning. 101 | 3. Otherwise, moderators will first respond to such behavior with a warning. 102 | 4. Moderators follow a soft "three strikes" policy - the community member may 103 | be given another chance, if they are receptive to the warning and change their 104 | behavior. 105 | 5. If the community member is unreceptive or unreasonable when warned by a 106 | moderator, or the warning goes unheeded, they may be banned for a first or 107 | second offense. Repeated offenses will result in the community member being 108 | banned. 109 | 110 | ## Scope 111 | 112 | This Code of Conduct and the enforcement policies listed above apply to all 113 | Adafruit Community venues. This includes but is not limited to any community 114 | spaces (both public and private), the entire Adafruit Discord server, and 115 | Adafruit GitHub repositories. Examples of Adafruit Community spaces include 116 | but are not limited to meet-ups, audio chats on the Adafruit Discord, or 117 | interaction at a conference. 118 | 119 | This Code of Conduct applies both within project spaces and in public spaces 120 | when an individual is representing the project or its community. As a community 121 | member, you are representing our community, and are expected to behave 122 | accordingly. 123 | 124 | ## Attribution 125 | 126 | This Code of Conduct is adapted from the [Contributor Covenant][homepage], 127 | version 1.4, available at 128 | , 129 | and the [Rust Code of Conduct](https://www.rust-lang.org/en-US/conduct.html). 130 | 131 | For other projects adopting the Adafruit Community Code of 132 | Conduct, please contact the maintainers of those projects for enforcement. 133 | If you wish to use this code of conduct for your own project, consider 134 | explicitly mentioning your moderation policy or making a copy with your 135 | own moderation policy so as to avoid confusion. 136 | -------------------------------------------------------------------------------- /adafruit_displayio_ssd1306.py: -------------------------------------------------------------------------------- 1 | # SPDX-FileCopyrightText: 2019 Scott Shawcroft for Adafruit Industries 2 | # 3 | # SPDX-License-Identifier: MIT 4 | 5 | """ 6 | `adafruit_displayio_ssd1306` 7 | ================================================================================ 8 | 9 | DisplayIO driver for SSD1306 monochrome displays 10 | 11 | 12 | * Author(s): Scott Shawcroft 13 | 14 | Implementation Notes 15 | -------------------- 16 | 17 | **Hardware:** 18 | 19 | * `Monochrome 1.3" 128x64 OLED graphic display `_ 20 | * `Monochrome 128x32 I2C OLED graphic display `_ 21 | * `Monochrome 0.96" 128x64 OLED graphic display `_ 22 | * `Monochrome 128x32 SPI OLED graphic display `_ 23 | * `Adafruit FeatherWing OLED - 128x32 OLED `_ 24 | * Monochrome 0.49" 64x32 I2C OLED graphic display 25 | * Monochrome 0.66" 64x48 I2C OLED graphic display (eg https://www.amazon.com/gp/product/B07QF7QK6P) 26 | * Miniature 0.42" OLED 72x40 Display with Resin Lens 27 | * https://tindie.com/products/questwise-ventures/miniature-042-oled-72x40-display-with-resin-lens 28 | * Might work on other sub-128 width display: Dots 72x40, 64x48, 96x16 29 | 30 | **Software and Dependencies:** 31 | 32 | * Adafruit CircuitPython (version 5+) firmware for the supported boards: 33 | https://github.com/adafruit/circuitpython/releases 34 | 35 | """ 36 | 37 | from busdisplay import BusDisplay 38 | 39 | try: 40 | from typing import Union 41 | 42 | from fourwire import FourWire 43 | from i2cdisplaybus import I2CDisplayBus 44 | except ImportError: 45 | pass 46 | 47 | __version__ = "0.0.0+auto.0" 48 | __repo__ = "https://github.com/adafruit/Adafruit_CircuitPython_DisplayIO_SSD1306.git" 49 | 50 | # Sequence from page 19 here: https://cdn-shop.adafruit.com/datasheets/UG-2864HSWEG01+user+guide.pdf 51 | _INIT_SEQUENCE = ( 52 | b"\xae\x00" # DISPLAY_OFF 53 | b"\x20\x01\x00" # Set memory addressing to horizontal mode. 54 | b"\x81\x01\xcf" # set contrast control 55 | b"\xa1\x00" # Column 127 is segment 0 56 | b"\xa6\x00" # Normal display 57 | b"\xc8\x00" # Normal display 58 | b"\xa8\x01\x3f" # Mux ratio is 1/64 59 | b"\xd5\x01\x80" # Set divide ratio 60 | b"\xd9\x01\xf1" # Set pre-charge period 61 | b"\xda\x01\x12" # Set com configuration 62 | b"\xdb\x01\x40" # Set vcom configuration 63 | b"\x8d\x01\x14" # Enable charge pump 64 | b"\xaf\x00" # DISPLAY_ON 65 | ) 66 | 67 | 68 | class SSD1306(BusDisplay): 69 | """ 70 | SSD1306 driver 71 | 72 | :param int width: The width of the display 73 | :param int height: The height of the display 74 | :param int rotation: The rotation of the display in degrees.

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.

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.
