Here's an Arduino code for capturing video with the ESP32-CAM module:
#include "esp_camera.h"
// Define camera pins
#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
#define Y8_GPIO_NUM 34
#define Y7_GPIO_NUM 39
#define Y6_GPIO_NUM 36
#define Y5_GPIO_NUM 21
#define Y4_GPIO_NUM 19
#define Y3_GPIO_NUM 18
#define Y2_GPIO_NUM 5
#define VSYNC_GPIO_NUM 25
#define HREF_GPIO_NUM 23
#define PCLK_GPIO_NUM 22
void setup() {
Serial.begin(115200);
// Initialize camera
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;
// Set the resolution
config.frame_size = FRAMESIZE_SVGA;
config.jpeg_quality = 12;
config.fb_count = 1;
// Initialize the camera
esp_err_t err = esp_camera_init(&config);
if (err != ESP_OK) {
Serial.printf("Camera init failed with error 0x%x", err);
return;
}
Serial.println("Camera initialized successfully");
}
void loop() {
// Start video streaming
Serial.println("Starting video streaming");
camera_fb_t *fb = NULL;
esp_err_t res = ESP_OK;
while (true) {
fb = esp_camera_fb_get();
if (!fb) {
Serial.println("Failed to capture frame");
res = ESP_FAIL;
break;
}
// Send the frame to serial port
Serial.write(fb->buf, fb->len);
// Release the memory
esp_camera_fb_return(fb);
}
// Stop video streaming
Serial.println("Stopping video streaming");
}
This code initializes the ESP32-CAM camera and starts video streaming using the esp_camera_fb_get()
function. The frames are then sent to the serial port using the Serial.write()
function. You can adjust the camera settings such as resolution and quality in the camera_config_t
struct. Note that video streaming can be resource-intensive and may require additional optimization for better performance.
