MaixPy-v1 (K210) usage refer to MaixPy-v1. MaixPy v4 does not support Maix-I Maix-II series hardware, please upgrade to the MaixCAM platform.
If you like MaixPy, please give a star ⭐️ to the MaixPy open source project to encourage us to develop more features.
English
from maix import camera, display, image, nn
classifier = nn.Classifier(model="/root/models/mobilenetv2.mud")
cam = camera.Camera(classifier.input_width(), classifier.input_height(), classifier.input_format())
dis = display.Display()
while 1:
img = cam.read()
res = classifier.classify(img)
max_idx, max_prob = res[0]
msg = f"{max_prob:5.2f}: {classifier.labels[max_idx]}"
img.draw_string(10, 10, msg, image.COLOR_RED)
dis.show(img)
Serial Communication:
from maix import uart
devices = uart.list_devices()
serial = uart.UART(devices[0], 115200)
serial.write_str("hello world")
print("received:", serial.read(timeout = 2000))
I2C Communication:
from maix import i2c
devices = i2c.list_devices()
dev1 = i2c.I2C(devices[0], freq=100000)
slaves = dev1.scan()
print("find slaves:", slaves)
dev1.writeto(0x12, b'hello')
print("received:", dev1.readfrom(0x12, 5))
