使用esp32-cam设备通过micropython脚本拍摄照片

一、取得固件

办法1：克隆源码，自己编译固件

clone

git clone https://github.com/tsaarni/micropython-with-esp32-cam.git micropython

build

cd micropython/mpy-cross
make
cd ../ports/esp32 
git submodule update --init 
make V=1 SDKCONFIG=boards/sdkconfig.esp32cam -j

办法2:直接下载编译好的固件。

注：micropython的官方固件 并不支撑cam

二、usbttl与esp32 cam连接：

三、使用thonny烧录：

烧录结束后，记得把链接帽（IO0 GNO）去掉。

这样，就进入了调试界面：

接下来，新建文件，保存在esp32cam设备中，文件名为main.py

import usocket as socket
import network
import esp
import camera
import gc
esp.osdebug(None)
gc.collect()
ssid = 'wifi'
password = '123456'
station = network.WLAN(network.STA_IF)
station.active(True)
station.connect(ssid, password)
while station.isconnected() == False:
  pass
print('Connection successful')
print(station.ifconfig())
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.bind(('', 80))
s.listen(5)
while True:
  conn, addr = s.accept()
  print('Got a connection from %s' % str(addr))
  request = conn.recv(1024)
  request = str(request)
  print('Content = %s' % request)
  on = request.find('/capture')
  if on == 6:
      camera.init()
      buf = camera.capture()
      conn.send('HTTP/1.1 200 OK\n')
      conn.send('Content-Type: image/jpg\n')
      conn.send('Connection: close\n\n')
      conn.sendall(buf)
      camera.deinit()
      conn.close()
  else:
      conn.send('HTTP/1.1 200 OK\n')
      conn.send('Content-Type: text/html\n')
      conn.send('Connection: close\n\n')
      conn.sendall("hello")
      conn.close()

翻开浏览器，输入该设备的ip：

访问：

把 192.168.101.197 替换成你的 esp32cam地址

更新版：添加闪光灯
