Hi Andreas,
I need help, I have compiled the firmware, but the data does not show how the antenna must be, any hypotheses ... a coil on ferrite ...? coil in the air ...? how should it be connected to the ESP32 directly to the pin, or there is a resistor ...?
I thank you in advance
Best regards Pino ...
Hi, Andreas,
following the question in #5, please, once again, share the idea of how have you connected the antenna circuit shown in video 287 to ESP32. In the video, which is for Raspberry, you are using two GPIOs: GPIO 4 and GPIO 17, while in the ESP32 code you only have one #define ANTENNAPIN 15
.
Referencing to video 287, I would say that ANTENNAPIN should be related to GPIO 17. I am not sure if I correctly understand the statement: "GPIO 4 is used to create a fixed frequency". How is that achievied? Just by setting the state to high? Or am I wrong? Please comment on that.
Btw., since esp32 v3.0.0, these functions ledcSetup
and ledcAttachPin
have been removed and substituted with ledcAttach
that merges the two former functions. To compile the code, I commented out the corresponding two lines:
// ledcSetup(0, 77500, 8); // DCF77 frequency
// ledcAttachPin(ANTENNAPIN, 0); // This Pin, or another one you choose, has to be attached to the antenna
and used the following one instead:
ledcAttach(ANTENNAPIN, 77500, 8);
Hi.
I'm compiling this code for the Wemos D1 mini and results on this error.
But compiles fine to the ESP32 Wrover.
Am I missing something?
Thanks.
Hi. Tried to get worked on ESP-WROOM-32 but got sync error. I have several Casio RC watches, I can get time with the real Germany signal but got an error with emulated. The watches shows high receiving level, I can see generated time messages in console, even LED is blinking when added to the antenna wire. The antenna is a 20 wire turns around the watches, just for the test.
Wifi is connected, ntp time is ok.
Hi,
thank you for this excellent program! Works really nice.
I would like to use the CONTINUOUSMODE option, but there is a reference to cronCheck() function, which is missing in the code.
Do you have it in your notes, somewhere? I am not capable to write it myself, yet :)
Best Regards,
Wieslaw
