I cannot guaruntee compatibility with other scanners/tags.\n- [ACR122U](https://www.acs.com.hk/en/products/3/acr122u-usb-nfc-reader/)\n- [NTAG213](https://www.nxp.com/products/rfid-nfc/nfc-hf/ntag-for-tags-and-labels/ntag-213-215-216-nfc-forum-type-2-tag-compliant-ic-with-144-504-888-bytes-user-memory:NTAG213_215_216)\n\nYou should be able to find these easily on your favorite online marketplace.\n\n## Installation\n\n### Microsoft Store\n~~The easiest way to install Summoner is via the Microsoft Store.~~ Currently there is an issue where the app crashes instantly when installed from the store. See [#17](https://github.com/halomademeapc/GravyVrc.Summoner/issues/17).\n[![Get it from the Microsoft Store](https://get.microsoft.com/images/en-US%20dark.svg)](https://apps.microsoft.com/store/detail/9PBSBFXXP0DF?launch=true\u0026mode=mini)\n\n### Manual Installation\nYou can also head to the [releases](https://github.com/halomademeapc/GravyVrc.Summoner/releases) page and download non-packaged builds for your platform from there.\n\n## Usage\n![image](https://github.com/halomademeapc/GravyVrc.Summoner/assets/5904472/d33a4426-c59e-4db3-a92a-810ef4432c75)\n\nClick **Add Parameter** to add parameters to set on your avatar anytime the tag is scanned while the app is open.  \n\n![image](https://github.com/halomademeapc/GravyVrc.Summoner/assets/5904472/2d8e5483-2eaf-40b9-91d0-4d7f8af46e4e)\n\nParameters can be a integer, float, or boolean type.\n\n![image](https://github.com/halomademeapc/GravyVrc.Summoner/assets/5904472/f31216f2-c4bc-45d2-8a72-148f8131b691)\n\nThe **Write Tag** button will be enabled if all parameters are valid and a tag is detected on a compatible reader.  You can also use the **Set Value** button to test your parameters without overwriting a tag or without a tag present.  Be aware that placing a tag on the scanner will load its values into the UI so make sure you place the tag down before you start making your edits otherwise they may be lost.\n\n## Technical Bits\n### Libraries\nSummoner's UI is built on Windows App SDK + WinUI 3 with .NET 6.  The app talks to your NFC reader using [pcsc-sharp](https://github.com/danm-de/pcsc-sharp) and to VRChat via [VRCOscLib](https://github.com/ChanyaVRC/VRCOscLib).  Data is serialized using [MessagePack](https://github.com/neuecc/MessagePack-CSharp).\n\n### Data Format\nData is stored on the tags in 4-byte blocks using the following arrangement:\n| Block | Usage                 |\n|-------|-----------------------|\n| 4     | Identifying Signature |\n| 5     | Content Size Header   |\n| 6..   | Serialized Content    |\n\n### Utility Parameters\nSummoner sets a couple of parameters in addition to what you specify in the UI that you can use to drive animations.\n\n**Gv/Summoner/Triggered**: Switches to `true` for 100ms anytime Summoner sets a value.\n**Gv/Summoner/Present**: Set to `true` while an NFC tag is detected on your reader.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fhalomakes%2Fgravyvrc.summoner","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fhalomakes%2Fgravyvrc.summoner","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fhalomakes%2Fgravyvrc.summoner/lists"}
