Also, you may need to install [git](http://git-scm.com/) in your system. After install that you should have the command line tools of PlatformIO. Please test it with `pio --help`. Then please run the next command for build and upload the firmware:\n\n```bash\npio run --target upload\n```\n\n## Configuration\n\n![Clock settings](pics/preview.jpg)\n\nUsing your USB cable, connect it and run:\n\n```bash\npio device monitor\n```\n\nPress enter and type help. You should see the configuration commands for setup your WiFi and time settings.\n\nFor instance to set Tokio time zone, select the correct time zone code [here](https://raw.githubusercontent.com/nayarsystems/posix_tz_db/master/zones.csv) and set it:\n\n```bash\nntpzone JST-9\n```\n\n## CLI preview\n\n![ESP32S3 Clock CLI preview](pics/cli.jpg)\n\n## Credits\n\nThe original version was from [LilyGO](https://github.com/Xinyuan-LilyGO/T-Display-S3), but this version burned the libraries and dependencies into the main repository. Also the LVGL config was into the hidden directory. For show the best practices I did this basic example using some tools from PlatformIO to suppress this bad practices.  \n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fhpsaturn%2Fesp32-s3-clock","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fhpsaturn%2Fesp32-s3-clock","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fhpsaturn%2Fesp32-s3-clock/lists"}
