non-void function error #8

MikeGitHubRPi · 2021-11-16T19:01:26Z

Hello James, thank you very much for your code.

I have a problem when compiling in Arduino IDE:

In function 'esp_err_t start_avi()':
warning: no return statement in function returning non-void [-Wreturn-type]
} // end of start avi
^

In function 'esp_err_t another_save_avi(camera_fb_t*)':
warning: no return statement in function returning non-void [-Wreturn-type]
} // end of another_pic_avi
^

In function 'esp_err_t end_avi()':
warning: no return statement in function returning non-void [-Wreturn-type]
}
^

In function 'bool init_wifi()':
warning: control reaches end of non-void function [-Wreturn-type]
Serial.println(WiFi.localIP());

I've tried rolling back to library versions described in the header but same response.

Any idea about that warning?

Thank you

I think you have too many compiler warnings turned on
Try this in Arduino File Preferences ...

MikeGitHubRPi · 2021-11-16T20:43:43Z

Hello James, thank you for your answer.
The problem are not the warnings themselves, I can't start the communication with esp32-cam. I only see this in the serial monitor.

The last three lines repeat continuously.

Thank you

Is this the code you have?
You seem to have a loop from 1009 back to 999, without going up to 971 (so not restarting procedure).

What is your timezone?
String TIMEZONE = "GMT0BST,M3.5.0/01,M10.5.0/02";

MikeGitHubRPi · 2021-11-16T22:03:17Z

My time zone is:

TIMEZONE = " CET-1CEST-2,M3.5.0/02,M10.5.0/03";

It's the same leaving the default timezone.

Yes, that's the code.

jameszah · 2021-11-26T19:42:44Z

Do you have a space at the beginning of that timezone string?
I'll try to have a look at it today.

MikeGitHubRPi · 2021-11-27T08:37:27Z

Hello,

That was a mistake with copy and paste from the code. There is no space.

Thank you

I have the same problem ....

If I comment the mDSN statement's my ESP32 keeps crashing ..

what is your "devname"? Is it a simple short text string - no spaces, punctuation, etc?
Is the IP address: 192.168.x.y changed ... it has real numbers on the serial monitor?
What is your esp32-arduino version ... like 1.6 or 2.0.2 ?
It crashed when dns is commented out, or commented in ... included?

mrWheel · 2022-01-18T17:42:19Z

@jameszah
devname = “CAM182”
Yes, IP address is a normal all numeric IP address
Esp-core 2.0.1 because 2.0.2 has problems with UniversalTelegramBot

It loops when dns is active like MikeGitHubRPi listed in his second comment.
It crashen when commented out.

Tried various tzChar strings (short (GMT) long, with first char as space and without first char space)

board is a TTGO-Camera. I edited the pins to a working set (from an other sketch).

jameszah · 2022-01-18T22:49:22Z

try new version 8.9

That non-void function return warning seems to be a new feature of the compiler 1.8.19 or so.
It gives a warning during the compile, but at run time, it keeps re-running the function until it gets a "return true" ???

Added a work-around to the main program for handshake timeout problem to avoid having to go back to 2.0.1

Also looked at the 4 old picture problem in another comment.

I suppose this is way people ask "what compiler, library, hardware, ...."

mrWheel · 2022-01-19T09:59:18Z

@jameszah
Thanks for this great software!

in setup() I altered this:

  Serial.println("---------------------------------");
  Serial.printf("ESP32-CAM Video-Telegram %s\n", vernum);
  Serial.println("---------------------------------");

  digitalWrite(FLASH_LED_PIN, flashState); //defaults to low

  pinMode(12, INPUT_PULLUP);        // pull this down to stop recording

  pinMode(33, OUTPUT);             // little red led on back of chip
  digitalWrite(33, LOW);           // turn on the red LED on the back of chip

What is gpio12? PIRpin?
gpio33 is the PIR sensor on my device!
better to use #define's for this is different on every board!!

I have added a tab setting_pins.h by 'LewisHe' (but renamed it camera_pins.h) and moved your AI_THINKER defines to the camera_pins.h file.
The beginning of the sketch now looks like this:

#include <WiFi.h>
#include <WiFiClientSecure.h>
#include "esp_camera.h"

/***************************************
 *  Board select
 **************************************/
/* Select your board here */
// #define T_Camera_JORNAL_VERSION
// #define T_Camera_MINI_VERSION
// #define T_Camera_PLUS_VERSION
// #define T_Camera_V05_VERSION
// #define T_Camera_V16_VERSION
// #define T_Camera_V162_VERSION
 #define T_Camera_V17_VERSION
// #define ESPRESSIF_ESP_EYE
// #define CAMERA_MODEL_AI_THINKER

#include "camera_pins.h"

I added #defines for PIR_PIN and FLASH_LED_PIN for every board type.

also in setupCamera()
I added:

  s->set_framesize(s, (framesize_t)framesize);
  s->set_quality(s, quality);
  //s->set_vflip(s, 1); //-- flip it <<-- uncomment this if camera is upside-down

I only use the esp32-cam module. I don't have those others to test.

You have to find our pir pin, determine if it active-high or active low, and then modify setupinterupts() for your board (at the link below after pirpin definition)

It prints out the status of your pir at the reboot to show you what your pir is telling you during boot.

Pin 12 is an sd-card pin on esp32-cam -- it does not do anything in this program.

int PIRpin = 13;
