出现这个错误提示,而且无法执行 def tick(timer):中的程序,也没有图像

请在这里粘贴代码import sensor, image, time from pyb import Pin, Timer, LED import utime a = Pin('P4', Pin.OUT_PP) b = Pin('P5', Pin.OUT_PP) sensor.reset() sensor.set_pixformat(sensor.RGB565) # 灰度更快 sensor.set_framesize(sensor.QQVGA) sensor.skip_frames(time = 2000) clock = time.clock() def tick(timer): clock.tick() #lens_corr(1.8)畸变矫正 print('2') img = sensor.snapshot().lens_corr(1.8) for c in img.find_circles(threshold = 3500, x_margin = 10, y_margin = 10, r_margin = 10,r_min = 2, r_max = 100, r_step = 2): img.draw_circle(c.x(), c.y(), c.r(), color = (255, 0, 0)) print(c) a.high() time.sleep_ms(200) a.low() for r in img.find_rects(threshold = 10000): img.draw_rectangle(r.rect(), color = (255, 0, 0)) for p in r.corners(): img.draw_circle(p[0], p[1], 5, color = (0, 255, 0)) print(r) b.high() time.sleep_ms(200) b.low() print("FPS %f" % clock.fps()) tim = Timer(2, freq=1) # 使用定时器2创建定时器对象-以1Hz触发 tim.callback(tick) # 将回调设置为tick函数 while (True): time.sleep_ms(1000) print('1')

中断服务函数不能使用新内存。所以不能在中断服务函数采集图像。
