Basic¶
1. MaixPy IDE¶
1.1 Download IDE¶
1.2 Steps：¶
Open the IDE and select the model of the development board in the upper toolbar.
选择 工具(Tool) ->
鼠标 选择开发板(Select board) ->
点击 T-Watch
2.The first program:Blink the LED¶
import time #import time, use delay sleep
from Maix import GPIO #import the GPIO function of Maix module, divided into general and high-speed
from fpioa_manager import * #import all of the module fpioa_manager, abbreviated as fm
fm.register(22,fm.fpioa.GPIO1) #general GPIO0 has been used. So use GPIO1
light=GPIO(GPIO.GPIO1,GPIO.OUT) #the code uses general GPIO1 for control by default
#fm.register(22,fm.fpioa.GPIOHS0) #high-speed GPIOHS0 is available. So use GPIOHS0
#light=GPIO(GPIO.GPIOHS0,GPIO.OUT) #when using high-speed IO, comment out the general IO code
while True: #while infinite loop
light.value(0) #set the low level of the LED to light up
time.sleep_ms(1000) #delay 1s
light.value(1) #set the LED high level, the light is off
time.sleep_ms(1000) #delay 1s
3. T-Watch Example¶
import lcd #import LCD screen library
import time #import time time library
import sensor #import sensor camera sensor library
from Maix import GPIO #import the GPIO function of Maix module, divided into general and high-speed
from fpioa_manager import * #import all of the module fpioa_manager, abbreviated as fm
#Turn on the screen backlight, please refer to turning on the LED light 1. The principle of LED.py is the same
fm.register(board_info.PIN17,fm.fpioa.GPIO0)
led=GPIO(GPIO.GPIO0,GPIO.OUT)
led.value(1) #1: Turn on the backlight 0: Turn off the backlight
lcd.init(freq=15000000) #LCD screen initialization operating frequency 15M
lcd.rotation(2) #LCD rotation mode setting 2: up 0: down 1: left 0: right
sensor.reset() #camera reset initialization
sensor.set_pixformat(sensor.RGB565) #camera image format RGB565 16 bits/pixel
sensor.set_framesize(sensor.QVGA) #camera image frame size QVGA
sensor.skip_frames(time=2000) #the frame skipping time of the camera is 2 seconds so that the image is transmitted to the screen stably
while(True): #while infinite loop execution
img = sensor.snapshot() #The camera gets the image data and assigns it to the variable img(image)
lcd.display(img) #LCD screen displays camera img image frame by frame
