2.板载ADC

(1)案例说明
  Haas506开发板有两个ADC接口,可以使用板载ADC接口进行数据测量。
(2)main.py

# coding=utf-8
# This is a sample Python script.
from driver import ADC
import utime as time
print("-------------------start adc test--------------------")
adc0 = ADC()
adc1=ADC()
for i in range(100):
    time.sleep(2)
    adc0.open("ADC0")
    adc1.open("ADC1")
    value0=adc0.read()
    value1=adc1.read()
    print("values of adc0 and adc1 ",value0,value1)
    adc0.close()
    adc1.close()
print("-------------------end adc test--------------------")
