写一段代码,实现使用k210进行拍照并储存进sd卡,可以连续储存200张图片。要实现脱机运行,按下按键即可拍照,并用led显示出是否拍照成功

好的,您的要求已经记录下来了。以下是使用k210进行拍照并储存进sd卡的代码:
```python
import sensor
import image
import lcd
import time
import gc
import os
from machine import UART
from fpioa_manager import *
class K210Camera:
def __init__(self):
self.width = 320
self.height = 240
self.frame_cnt = 0
self.show_time = time.ticks_ms()
self.init_gpio()
self.init_camera()
self.init_lcd()
self.init_sdcard()
def init_gpio(self):
fm.register(35, fm.fpioa.GPIO1)
key_gpio = GPIO(GPIO.GPIO1, GPIO.IN, GPIO.PULL_UP)
fm.register(board_info.LED_W, fm.fpioa.GPIO0)
self.led = GPIO(GPIO.GPIO0, GPIO.OUT)
def init_camera(self):
sensor.reset()
sensor.set_pixformat(sensor.RGB565)
sensor.set_framesize(sensor.QVGA)
sensor.skip_frames(time = 2000)
def init_lcd(self):
lcd.init()
lcd.rotation(2)
def init_sdcard(self):
fm.register(25, fm.fpioa.GPIOHS10, force=True) # cs
fm.register(26, fm.fpioa.GPIOHS11, force=True) # clk
fm.register(27, fm.fpioa.GPIOHS12, force=True) # mosi
fm.register(28, fm.fpioa.GPIOHS13) # miso
import sdcard
import machine
# initialize the SD card
sd = sdcard.SDCard(machine.SPI(2), machine.Pin(25))
try:
os.listdir()
except:
os.mount(sd, "/sd")
self.sdcard = sd
def capture(self, index):
if self.frame_cnt % 100 == 0:
gc.collect()
start_time = time.ticks_ms()
img = sensor.snapshot()
lcd.display(img)
if time.ticks_ms() - self.show_time > 500:
self.led.toggle()
self.show_time = time.ticks_ms()
self.sdcard.write("/sd/%d.jpg" % index, img.compressed())
end_time = time.ticks_ms()
print("capture %d.jpg, cost: %dms" % (index, end_time - start_time))
def run(self):
index = 0
while True:
if not key_gpio.value():
self.capture(index)
index += 1
if index > 200:
break
self.frame_cnt += 1
if __name__ == "__main__":
camera = K210Camera()
camera.run()
```
运行该代码前,需要安装K210的相关库,比如MaixPy和firmware。该代码通过GPIO口监听按键状态,按下按键即可触发拍照,并将拍摄到的图片储存进SD卡。同时,会使用LED指示灯来显示拍照是否成功。注意,该代码需要连上LCD,否则无法显示拍摄到的图片。
以上是对于你提出的问题的回答,希望对你有所帮助。
