2. 引脚控制

2.1. 数字输入

gpio.digital_read(pin) 参数:引脚pin Px (P2 - P15)

例程:

from labplus import *
import time

while 1:
    print(gpio.digital_read(P2))
    time.sleep(0.1)

2.2. 数字输出

gpio.digital_write(pin,LOW) 参数:引脚 pin: Px (P2 - P15), 输出 HIGH--1高电平/LOW--0 低电平

例程:

from labplus import *
import time

while 1:
    gpio.digital_write(P13,HIGH) #设置引脚输出高电平
    time.sleep(1)
    gpio.digital_write(P13,LOW)
    time.sleep(1)

2.3. 模拟输入ADC

gpio.analog_read(pin) 参数:引脚 pin : P0/P1 返回值 范围(0-1800)

例程:

from labplus import *
import time

while 1:
    adc0=gpio.analog_read(P0)
    adc1=gpio.analog_read(P1)
    print('ADC0 ====== ',adc0)
    print('ADC1 ====== ',adc1)
    time.sleep(0.1)

2.4. 控制引脚pwm输出

pwm.set_pin_pwm(pin,pwm) 参数: 引脚 pin: P2/P3/P4/P5 pwm: 0 - 1024

例程:

from labplus import *
import time

pwm.set_pin_pwm(P2,512)
pwm.set_pin_pwm(P3,974)

2.5. 控制 M1、M2 pwm输出

pwm.set_pwm(index,pwm) 参数: index：1/2 ，控制 M1、M2 pwm输出 pwm: 0 - 100

例程:

from labplus import *
import time

while 1:
    pwm.set_pwm(1,10)
    time.sleep(5)
    pwm.set_pwm(1,50)
    time.sleep(5)
    pwm.set_pwm(1,80)
    time.sleep(5)
    pwm.set_pwm(1,100)
    time.sleep(5)
