果然有坑，之前找的OPENMV官方固件，只打包了ARDUNIO的RP2040的OPENMV，pico版本的没有打包，不会打包的渣渣看了pico的配置，怎么都没法调试，再去试试看吧：
好在openmv的配置文件都是 omv_boardconfig.h 这个。
建议使用Ultimate PICO 16MB的FLASH RP2040
好吧和之前固件一样，只有QQVGA和RGB565,连jpg保存，二维码识别都没有，只有人脸和眼睛识别·。最多只能做一个RGB565 的QQVGA的串流模块，相关代码：
import sensor,image
sensor.set_pixformat(sensor.RGB565)
sensor.set_framesize(sensor.QQVGA)
eyes_cascade = image.HaarCascade("eye", stages=24)
face_cascade = image.HaarCascade("frontalface", stage = 25)
def face():
img = sensor.snapshot()
objects = img.find_features(face_cascade, threshold=0.5, scale_factor=1.25)
print(objects)
def eye():
img = sensor.snapshot()
objects = img.find_features(eyes_cascade, threshold=0.5, scale=1.5)
print(objects)
