This firmware uses an [improvement of Arduino-DCF77 library](https://github.com/hpsaturn/Arduino-DCF77), using an event callback to improve the GUI and signal representation.\n\n\u003ctable\u003e\n\t\u003ctr\u003e\n\t\t\u003ctd\u003e\n\t\t\tDon't forget to star ⭐ this repository\n\t\t\u003c/td\u003e\n\t\u003c/tr\u003e\n\u003c/table\u003e\n\n## Device\n\nThe current firmware was tested on 77.5KHZ single frequency device. It is the 4 pins version and it was bought in [Aliexpress](https://www.aliexpress.com/item/1005005254051736.html).\n\n## Wiring\n\n| M5StickC pin | DCF77 pin | Description |\n|:----:|:----:|:-------------|\n| 0 | P | PON: Enable/Disable |\n| 26 | T | Interrupt pin or data |\n| 3.3v | VDD | Positive (3.3v) |\n| GND  | GND | Ground / unlabeled pin |\n\n(see the photos in [Thingiverse](https://www.thingiverse.com/thing:6033436))\n\n## Usage\n\n**Some tips:**  \n\n- [x] Check the right device. Some devices has different frequencies for each country.\n- [x] Try to leave the device from away any radio or wireless interference or noise. The radio is very susceptible to noise.\n- [x] In indoors it works, but is possible that in some builds doesn't. Try in outdoors first.\n- [x] The position of the device for me was important, in horizontal is possible that it works better\n\n**Buttons:**\n\n- Left button: Power ON/Off\n- M5 Button: Backlight or brightness toggle\n- Right button: Unimplementened  \n\n## Installation\n\nPlease install first [PlatformIO](http://platformio.org/) open source ecosystem for IoT development compatible with **Arduino** IDE and its command line tools (Windows, MacOs and Linux). Also, you may need to install [git](http://git-scm.com/) in your system.\n\nFor the **default** board, the `M5StickCPlus`, only clone this and upload firmware via USB cable with a simple command:\n\n`pio run --target upload`\n\nor import the project in VSCode and build and run it.\n\n## Box\n\nIs a basic box - hat for these devices, for example M5StickC or M5StickC-Plus, also should be work in M5CoreInk device.\n\n[![Box DCF77 M5StickCPlus Hat](box/collage.jpg)](https://youtu.be/C50qMhYiE60)\n\n**Files:**  \n\n![DCF77 box base](box/dfc77_holder_vertical.stl)  \n![DCF77 box lid](box/dfc77_holder_vertical_lid.stl)  \n\nAlso in [Thingiverse](https://www.thingiverse.com/thing:6033436).  \n\n---\n\n## Thanks to\n\n@felmue to fix a sporadical crash.  \n@jcomas for the help and docs on https://t.me/esp_es  \nThe old [DCF77 library](https://github.com/thijse/Arduino-DCF77)  \nThe [Seiko documentation](https://www.seikowatches.com/instructions/html/SEIKO_8B92_EN/CWVVSYxxhbpilh)","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fhpsaturn%2Fm5stickc-dcf77-hat","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fhpsaturn%2Fm5stickc-dcf77-hat","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fhpsaturn%2Fm5stickc-dcf77-hat/lists"}
