Hello,
When I have an ESP32 – CAM and it takes a picture with a time interval and sends it(FTP?) not via SDcard but directly to a chart in my PC which is connected to the same WIFI network as the PC.
Does an Arduino sketch example or such exist to realize it?
Thank You

Hii, is there a way in Arduino IDE or different IDEs that you run two other tasks with two cores of esp32 but set each core frequency else for sample core 0 is performing its task with 10 Mhz frequency and core1 is doing its task with 80 Mhz?
Thank you

Hello Ashish, No, sorry, that kind of setup is physically impossible on current ESP chips as the two cores( and the main memory, for that matter) are in the same timer domain. Thank you

While trying to understand the cam web server code in one of the examples on Arduino IDE but I’m struggling to understand the code. What is it checking for and what is it configuring and lastly why is it needed in our code ? I have an AI thinker so do I still need this part of code ? Any help, links, etc. would be appreciated.
#if defined(CAMERA_MODEL_ESP_EYE) pinMode(13, INPUT_PULLUP); pinMode(14, INPUT_PULLUP); #endif // camera init esp_err_t err = esp_camera_init(&config); if (err != ESP_OK) { Serial.printf(“Camera init failed with error 0x%x”, err); return; } sensor_t * s = esp_camera_sensor_get(); // initial sensors are flipped vertically and colors are a bit saturated if (s->id.PID == OV3660_PID) { s->set_vflip(s, 1); // flip it back s->set_brightness(s, 1); // up the brightness just a bit s->set_saturation(s, -2); // lower the saturation } // drop down frame size for higher initial frame rate if(config.pixel_format == PIXFORMAT_JPEG){ s->set_framesize(s, FRAMESIZE_QVGA); } #if defined(CAMERA_MODEL_M5STACK_WIDE) || defined(CAMERA_MODEL_M5STACK_ESP32CAM) s->set_vflip(s, 1); s->set_hmirror(s, 1); #endif #if defined(CAMERA_MODEL_ESP32S3_EYE) s->set_vflip(s, 1); #endif

If you are using ESP32CAM AI Thinker, the embedded camera is an OV2640 so only part of the code will be compiled/executed, see below. The bottom line is you could leave code as-is, it should be ok Note that frame size can take following values : frame size QQVGA(160x120),HQVGA(240x176),QVGA(320x240)Read more

Hello Julian, The Arduino forum has a post that will do what you want, basically, take a picture and FTP it. Thank You
