Initialize an int variable called pictureNumber that that will generate the photo name: picture1.jpg, picture2.jpg, and so on. Wrong pin assignment will result in a failure to init the camera. Note: you might need to change the pin definition depending on the board you’re using. Pin definition for CAMERA_MODEL_AI_THINKER Then, define the pins for the AI-THINKER camera module. Here, we’ll only use one byte that allows us to generate up to 256 picture numbers. ESP32 Flash Memory – Store Permanent Data (Write and Read)ĭefine the number of bytes you want to access in the flash memory.

If you want to learn more about how to read and write data to the flash memory, you can follow the next tutorial: We also include the libraries needed to interact with the microSD card: #include "esp_camera.h"Īnd the EEPROM library to save permanent data in the flash memory. The code starts by including the necessary libraries to use the camera. Serial.println("This will never be printed") Turns off the ESP32-CAM white on-board LED (flash) connected to GPIO 4 Serial.printf("Saved file to path: %s\n", path.c_str()) Serial.println("Failed to open file in writing mode") įile.write(fb->buf, fb->len) // payload (image), payload length Serial.printf("Picture file name: %s\n", path.c_str()) įile file = fs.open(path.c_str(), FILE_WRITE) String path = "/picture" + String(pictureNumber) +".jpg" Path where new picture will be saved in SD Card initialize EEPROM with predefined size Serial.printf("Camera init failed with error 0x%x", err) WRITE_PERI_REG(RTC_CNTL_BROWN_OUT_REG, 0) //disable brownout detectorĬame_size = FRAMESIZE_UXGA // FRAMESIZE_ + QVGA|CIF|VGA|SVGA|XGA|SXGA|UXGAĮsp_err_t err = esp_camera_init(&config)

You can follow one of the next tutorials to install the ESP32 add-on, if you haven’t already: So you need the Arduino IDE installed as well as the ESP32 add-on. We’ll program the ESP32 board using Arduino IDE. However, we’ve tested with 16 GB SD card and it works well. Note: according to the product specifications, the ESP32-CAM should only support 4 GB SD cards.
