使用openmv将检测到的视频传输到esp8266-12f使用spi来传输视频并写出代码

以下是使用OpenMV将检测到的视频传输到ESP8266-12F，使用SPI来传输视频的代码示例：

在OpenMV端的代码：

import sensor, image, time
import network, usocket, sys
import gc, os

# 初始化摄像头
sensor.reset()
sensor.set_pixformat(sensor.RGB565) # or sensor.GRAYSCALE
sensor.set_framesize(sensor.QQVGA) # or sensor.QQVGA (2x the resolution of QQVGA)
sensor.set_windowing((80,60)) # look at center 240x240 pixels of the VGA resolution.
sensor.skip_frames(time = 2000)

# 初始化WiFi
SSID='your_ssid'
KEY='your_wifi_password'
WLAN=None
s = None

def connect_wifi():
    global WLAN, s
    gc.collect()
    WLAN = network.WINC()
    WLAN.connect(SSID, key=KEY)
    while not WLAN.isconnected():
        time.sleep(0.5)
        print("connecting to wifi...")
    print("Wifi connected succesfully")

    # 初始化socket连接
    s = usocket.socket(usocket.AF_INET, usocket.SOCK_STREAM)
    s.setsockopt(usocket.SOL_SOCKET, usocket.SO_REUSEADDR, 1)
    s.bind((WLAN.ifconfig()[0], 8080))
    s.listen(1)
    print("Socket server listening on port 8080")

# 发送数据
def send_data(data):
    try:
        conn, addr = s.accept()
        conn.send(data)
        conn.close()
    except Exception as e:
        print("Exception: ", e)

# 连接WiFi
connect_wifi()

# 主循环
while(True):
    clock = time.clock()

    # 捕获图像
    img = sensor.snapshot()

    # 检测到的物体数量
    objs = img.find_rects()

    # 绘制矩形
    for r in objs:
        img.draw_rectangle(r.rect(), color=(255, 0, 0))

    # 将图像数据打包成JPEG格式
    jpg = img.compressed(quality=50)

    # 发送数据
    send_data(jpg)

在ESP8266-12F端的代码：

#include <SPI.h>
#include <WiFi.h>

// WiFi设置
const char* ssid = "your_ssid";
const char* password = "your_wifi_password";

// 定义SPI引脚
#define SCK 14
#define MISO 12
#define MOSI 13
#define SS 15

void setup() {
  // 初始化串口
  Serial.begin(115200);

  // 初始化WiFi
  WiFi.begin(ssid, password);
  while (WiFi.status() != WL_CONNECTED) {
    delay(1000);
    Serial.println("Connecting to WiFi...");
  }
  Serial.println("WiFi connected");

  // 初始化SPI
  SPI.begin(SCK, MISO, MOSI, SS);
}

void loop() {
  // 建立TCP连接
  WiFiClient client;
  if (!client.connect("192.168.1.101", 8080)) {
    Serial.println("Connection failed");
    delay(1000);
    return;
  }

  // 发送请求
  client.print("GET / HTTP/1.0\r\n\r\n");

  // 接收响应
  while (client.connected()) {
    if (client.available()) {
      Serial.write(client.read());
    }
  }
  client.stop();
}

请注意，在ESP8266-12F端的代码仅仅是简单地接收数据，并没有对接收到的数据进行处理。您需要根据具体的需求对接收到的图像数据进行解码和处理。
