How to add #include <esp32-hal-time.h>

simogaspa84 · June 16, 2022, 9:14am

Hi I am working with esp32 with platformio…

From a .cpp file under the lib folder how can I include the following header file ?

#include <esp32-hal-time.h>

Thanks a lot

That should already be correct – is there an error after doing an IntelliSense rebuild (Ctrl+Shift+P → Intelli)?

Adding the following include

#include <esp32-hal-time.c>

#include <esp32-hal-time.c>

and then calling the following function

getLocalTime(&time_test);

causes the crash of the firmware…

But compiling i don’t have issues…

Can you tell me why Max ?

Thanks

Sorry I measread the header file name (timer instead of time).

The functions should be available when just using

#include <Arduino.h>
#include <time.h>

does that work better?

If not, post the full code.

I can especially recomment just using this piece of code

          void setClock() {
            configTime(0, 0, "pool.ntp.org");
          
          
  Serial.print(F("Waiting for NTP time sync: "));
            time_t nowSecs = time(nullptr);
            while (nowSecs < 8 * 3600 * 2) {
              delay(500);
              Serial.print(F("."));
              yield();
              nowSecs = time(nullptr);
            }
          
          
  Serial.println();
            struct tm timeinfo;
            gmtime_r(&nowSecs, &timeinfo);
            Serial.print(F("Current time: "));
            Serial.print(asctime(&timeinfo));
          }
