你可以使用ESP32-CAM模块来驱动USB摄像头,以下是一个简单的示例代码:
#include "esp_camera.h"
#include <WiFi.h>
// Replace with your network credentials
const char* ssid = "your_SSID";
const char* password = "your_PASSWORD";
void setup() {
Serial.begin(115200);
WiFi.begin(ssid, password);
while (WiFi.status() != WL_CONNECTED) {
delay(1000);
Serial.println("Connecting to WiFi...");
}
Serial.println("Connected to WiFi");
// Initialize camera
camera_config_t config;
config.ledc_channel = LEDC_CHANNEL_0;
config.ledc_timer = LEDC_TIMER_0;
config.pin_d0 = 5;
config.pin_d1 = 18;
config.pin_d2 = 19;
config.pin_d3 = 21;
config.pin_d4 = 36;
config.pin_d5 = 39;
config.pin_d6 = 34;
config.pin_d7 = 35;
config.pin_xclk = 0;
config.pin_pclk = 22;
config.pin_vsync = 25;
config.pin_href = 23;
config.pin_sscb_sda = 26;
config.pin_sscb_scl = 27;
config.pin_pwdn = 32;
config.pin_reset = -1;
config.xclk_freq_hz = 20000000;
config.pixel_format = PIXFORMAT_JPEG;
if(psramFound()){
config.frame_size = FRAMESIZE_UXGA;
config.jpeg_quality = 10;
config.fb_count = 2;
} else {
config.frame_size = FRAMESIZE_SVGA;
config.jpeg_quality = 12;
config.fb_count = 1;
}
// 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;
}
}
void loop() {
// Take picture
camera_fb_t* fb = esp_camera_fb_get();
if (!fb) {
Serial.println("Camera capture failed");
return;
}
// Send picture to server
WiFiClient client;
if (!client.connect("your_server_address", 80)) {
Serial.println("Connection to server failed");
return;
}
client.println("POST /upload HTTP/1.1");
client.println("Host: your_server_address");
client.println("Content-Type: image/jpeg");
client.print("Content-Length: ");
client.println(fb->len);
client.println();
client.write(fb->buf, fb->len);
client.println();
Serial.println("Picture sent to server");
// Free memory
esp_camera_fb_return(fb);
// Wait 5 seconds before taking another picture
delay(5000);
}
