The code starts past including the necessary libraries to use the camera. Nosotros also include the libraries needed to interact with the microSD card:

          #include "esp_camera.h" #include "Arduino.h" #include "FS.h"                // SD Card ESP32 #include "SD_MMC.h"            // SD Card ESP32 #include "soc/soc.h"           // Disable brownour issues #include "soc/rtc_cntl_reg.h"  // Disable brownour problems #include "commuter/rtc_io.h" #include <EEPROM.h>            // read and write from flash retention        

And the EEPROM library to save permanent information in the flash memory.

          #include <EEPROM.h>        

If you lot desire to acquire more than about how to read and write data to the flash retentiveness, you tin can follow the next tutorial:

• ESP32 Flash Retention – Store Permanent Data (Write and Read)

Define the number of bytes you lot want to access in the wink memory. Here, we'll just employ 1 byte that allows united states of america to generate up to 256 picture numbers.

          #define EEPROM_SIZE 1        

Then, define the pins for the AI-THINKER camera module.

          // Pivot definition for CAMERA_MODEL_AI_THINKER  #define PWDN_GPIO_NUM     32 #define RESET_GPIO_NUM    -1 #define XCLK_GPIO_NUM      0 #define SIOD_GPIO_NUM     26 #define SIOC_GPIO_NUM     27    #define Y9_GPIO_NUM       35 #ascertain Y8_GPIO_NUM       34 #ascertain Y7_GPIO_NUM       39 #define Y6_GPIO_NUM       36 #ascertain Y5_GPIO_NUM       21 #ascertain Y4_GPIO_NUM       19 #ascertain Y3_GPIO_NUM       18 #define Y2_GPIO_NUM        5 #define VSYNC_GPIO_NUM    25 #define HREF_GPIO_NUM     23 #ascertain PCLK_GPIO_NUM     22        

Note: y'all might need to alter the pin definition depending on the board you're using. Wrong pin assignment will result in a failure to init the camera.

Initialize an int variable called pictureNumber that that will generate the photo name: picture1.jpg, picture2.jpg, and so on.

          int pictureNumber = 0;        

All our code is in the setup(). The code only runs once when the ESP32 wakes up (in this case when you printing the on-board RESET push).

Define the photographic camera settings:

          camera_config_t config; config.ledc_channel = LEDC_CHANNEL_0; config.ledc_timer = LEDC_TIMER_0; config.pin_d0 = Y2_GPIO_NUM; config.pin_d1 = Y3_GPIO_NUM; config.pin_d2 = Y4_GPIO_NUM; config.pin_d3 = Y5_GPIO_NUM; config.pin_d4 = Y6_GPIO_NUM; config.pin_d5 = Y7_GPIO_NUM; config.pin_d6 = Y8_GPIO_NUM; config.pin_d7 = Y9_GPIO_NUM; config.pin_xclk = XCLK_GPIO_NUM; config.pin_pclk = PCLK_GPIO_NUM; config.pin_vsync = VSYNC_GPIO_NUM; config.pin_href = HREF_GPIO_NUM; config.pin_sscb_sda = SIOD_GPIO_NUM; config.pin_sscb_scl = SIOC_GPIO_NUM; config.pin_pwdn = PWDN_GPIO_NUM; config.pin_reset = RESET_GPIO_NUM; config.xclk_freq_hz = 20000000; config.pixel_format = PIXFORMAT_JPEG;                  

Apply the following settings for a camera with PSRAM (like the one we're using in this tutorial).

          if(psramFound()){   config.frame_size = FRAMESIZE_UXGA; // FRAMESIZE_ + QVGA|CIF|VGA|SVGA|XGA|SXGA|UXGA   config.jpeg_quality = ten;   config.fb_count = 2; }        

If the lath doesn't have PSRAM, set the following:

          else {   config.frame_size = FRAMESIZE_SVGA;   config.jpeg_quality = 12;   config.fb_count = 1; }        

Initialize the camera:

          // Init Camera esp_err_t err = esp_camera_init(&config); if (err != ESP_OK) {   Serial.printf("Photographic camera init failed with error 0x%x", err);   return; }        

Initialize the microSD carte du jour:

          //Serial.println("Starting SD Menu"); if(!SD_MMC.begin()){   Serial.println("SD Card Mountain Failed");   render; }   uint8_t cardType = SD_MMC.cardType(); if(cardType == CARD_NONE){   Serial.println("No SD Menu fastened");   return; }        

More information about how to employ the microSD bill of fare can be establish in the post-obit projection:

• ESP32 Data Logging Temperature to MicroSD Card

The post-obit lines have a photo with the camera:

          camera_fb_t * fb = Zip;  // Have Motion-picture show with Photographic camera fb = esp_camera_fb_get();   if(!fb) {   Serial.println("Photographic camera capture failed");   return; }        

Afterward that, initialize the EEPROM with the size defined before:

          EEPROM.brainstorm(EEPROM_SIZE);        

The movie number is generated by adding 1 to the electric current number saved in the flash retention.

          pictureNumber = EEPROM.read(0) + 1;        

To salvage the photograph in the microSD carte du jour, create a path to your file. We'll save the photograph in the main directory of the microSD menu and the file name is going to be (picture1.jpg, picture2.jpg, picture3.jpg, etc…).

          String path = "/movie" + String(pictureNumber) +".jpg";        

These next lines relieve the photo in the microSD card:

          fs::FS &fs = SD_MMC;  Serial.printf("Picture file proper noun: %s\n", path.c_str());  File file = fs.open up(path.c_str(), FILE_WRITE); if(!file){   Series.println("Failed to open file in writing mode"); }  else {   file.write(fb->buf, fb->len); // payload (image), payload length   Serial.printf("Saved file to path: %s\northward", path.c_str());   EEPROM.write(0, pictureNumber);   EEPROM.commit(); } file.shut();        

After saving a photo, we salvage the current picture number in the flash memory to keep track of the number of photos taken.

          EEPROM.write(0, pictureNumber); EEPROM.commit();        

When the ESP32-CAM takes a photograph, it flashes the on-board LED. After taking the photo, the LED remains on, so we send instructions to turn it off. The LED is connected to GPIO iv.

          pinMode(4, OUTPUT); digitalWrite(4, LOW); rtc_gpio_hold_en(GPIO_NUM_4);        

Finally, we put the ESP32 in deep sleep.

          esp_deep_sleep_start();        

Because we don't pass any argument to the deep sleep function, the ESP32 board volition exist sleeping indefinitely until RESET.

ESP32-CAM Upload Code

To upload lawmaking to the ESP32-CAM lath, connect it to your reckoner using an FTDI developer. Follow the adjacent schematic diagram:

Many FTDI programmers have a jumper that allows you to select three.3V or 5V. Make sure the jumper is in the right place to select 5V.

Important: GPIO 0 needs to be connected to GND and so that you're able to upload code.

ESP32-CAM	FTDI Programmer
GND	GND
5V	VCC (5V)
U0R	TX
U0T	RX
GPIO 0	GND

To upload the lawmaking, follow the next steps:

i) Get to Tools > Lath and select AI-Thinker ESP32-CAM.

2) Go to Tools > Port and select the COM port the ESP32 is continued to.

3) Then, click the upload button to upload the code.

four) When you starting time to come across these dots on the debugging window as shown below, press the ESP32-CAM on-board RST button.

After a few seconds, the code should be successfully uploaded to your board.

Sit-in

Later on uploading the lawmaking, remove the jumper that connects GPIO 0 from GND.

Open up the Serial Monitor at a baud rate of 115200. Printing the ESP32-CAM reset push. It should initialize and accept a photo. When it takes a photo it turns on the flash (GPIO 4).

Bank check the Arduino IDE Serial Monitor window to run into if everything is working every bit expected. As yous can run across, the motion-picture show was successfully saved in the microSD card.

Note: if you're having issues with the ESP32-CAM, take a look at our troubleshooting guide and see if it helps: ESP32-CAM Troubleshooting Guide: Most Common Problems Fixed

After making sure that everything is working as expected, y'all can disconnect the ESP32-CAM from the FTDI programmer and power information technology using an contained power supply.

To meet the photos taken, remove the microSD card from the microSD card slot and insert it into your computer. You should have all the photos saved.

The quality of your photograph depends on your lighting atmospheric condition. As well much light tin can ruin your photos and dark environments will result in many black pixels.
