# esp32-DCF77_Analyzer_Clock

An ESP32 TFT interpretation of the @deruiter's [DCF77-Analyzer-Clock-V2.0](https://github.com/deruiter/DCF77-Analyzer-Clock-V2.0)

Hardware Requirements:

----------------------

  - ESP32

  - TFT (160*128 minimum recommended, working on elastic design to cover higher resolutions)

  - DCF77 Atomic clock module ( such as this one https://www.universal-solder.ca/product/canaduino-60khz-atomic-clock-receiver-module-wwvb-msf-jjy60/ (WWVB/JJY60/MSF/DCF77) or https://www.pollin.de/p/dcf-77-empfangsmodul-dcf1-810054 (DCF77))

  - RTC Module (preferably i2c, e.g. a 5V DS1307 or 3V3 DS3231)

  - Buttons (optional)

  - Speaker (optional)



Software Requirements:

----------------------

  - M5Stack Core or ESP32-Chimera-Core for compatibility https://github.com/tobozo/ESP32-Chimera-Core (replaces M5Stack Core, adds support for Odroid-Go, TTGO-TS, Wrover-Kit LoLin D-32Pro)

  - Bodmer's JPEGDecoder for rendering jpeg in sprites https://github.com/Bodmer/JPEGDecoder



Running on an ODROID-GO:

  Thanks to the ESP32-Chimera-Core, the clock runs fine and flawless on an ODROID-GO (with sound output and buttons support for A/B/MENU).

  

  ODROID-GO esp32-DCF77 Analyzer Clock

  

  The hardware components has to be connected to the ODROID-GO's 10-pin connector:

  

  - The DCF modules positive pulse output has to be connected to `IO4` (5).

  - The RTC should be a DS3231 for convenience (3V3 system). Connect the supply pins to the ODROID-GO `P3V3` (6) and `GND` (1), `SDA` to `IO15` (4) and SCL to `IO12` (3) (hopefully the RTC will never need to do a clock stretching, because `IO12` is a buffered output pin, not an open-collector/-drain).

  

  To build a suitable ODROID-GO firmware file the following steps have to be proceeded:



  - Uncomment the `#define CONFIG_OGO` in the `Config.h` (comment out any other of the platforms).

  - Activate the verbose compiler output at the Arduino IDE preferences.

  - Select the `ORDOID ESP32` as target in the Arduiono IDE.

  - Build the firmware (just clicking the checkmark).

  - When successfully finished the build process, watch one of the last lines of the Arduino IDE console output and navigate to the temporary directory where the compiler puts the file `esp32-DCF77_Analyzer_Clock.ino.elf`.

  - There you will find a file named **`esp32-DCF77_Analyzer_Clock.ino.bin`**. Copy this file to a directory (of your choice), where the executable `mkfw` (Linux) or `mkfw.exe` (Windows, get it here: [https://forum.odroid.com/viewtopic.php?t=31939](https://forum.odroid.com/download/file.php?id=9325&sid=f3db9325d02e3d69aa28fcd5d3e3a064)) could be found.

  - Copy the file `\assets\img\OGO_DCF77_Analyzer_Clock_Logo.raw` to the same directory (icon file created as described [here](https://wiki.odroid.com/odroid_go/arduino_app#make_tile_image_with_ffmpeg)).

  - Create the firmware with `mkfw "DCF77 Anylyzer Clock" OGO_DCF77_Analyzer_Clock_Logo.raw 0 16 1048576 app esp32-DCF77_Analyzer_Clock.ino.bin` (Windows) or `./mkfw "DCF77 Anylyzer Clock" OGO_DCF77_Analyzer_Clock_Logo.raw 0 16 1048576 app esp32-DCF77_Analyzer_Clock.ino.bin` (Linux).

  - Rename the file with `ren firmware.fw esp32-DCF77_Analyzer_Clock.fw` (Windows) or `mv firmware.fw esp32-DCF77_Analyzer_Clock.fw` (Linux).

  - Put the firmware file `esp32-DCF77_Analyzer_Clock.fw` to your ODROID-GO's SD card in the `odroid\firmware` folder and install it from there to your ODROID-GO.

  - After a software reboot you need to power the ODROID-GO off and on again to re-init the incomplete graphics.



CREDITS:

--------

  I learned a lot from Erik de Ruiter who learned a lot from the work of Matthias Dalheimer and Thijs Elenbaas

  who made their own DCF77 decoders.



  Although the changes I made are far from optimistic, this code has wisdom DNA in its roots!



  Without the incredible work of these geniuses I would not have known where to start and how to write those credits :)



  Huge thanks to [@BrettOliver](https://github.com/brettoliver) for fueling the code with a 320x240 UI, implementing the leap second, and [much more](http://www.brettoliver.org.uk/DCF77_Signal_Generator_Analyzer/DCF77_Signal_Generator.htm#leapsecond)
