Question

我正在尝试使用Raspberry PI编程AD8232心脏监测器，据我所知，我为ump和ADC ads1115安装了所有正确的软件包。我遇到的问题是当我尝试运行代码时，我得到一个值错误：在初始化文件“/usr/lib/python2.7/dist-packages/upm/pyupm_ad8232.py”，第170行 this = _pyupm_ad8232.new_AD8232（loPlus，loMinus，output，aref） ValueError：UPM无效参数：指定的AIO引脚无效 - 您有ADC吗？任何人都可以帮助解决这个问题，我正在使用的python脚本如下谢谢。

#!/usr/bin/env python3

from __future__ import print_function
import time, sys, signal, atexit
from upm import pyupm_ad8232 as upmAD8232
from upm import pyupm_ads1x15 as upm

def main():
    # Instantiate a AD8232 sensor on digital pins 10 (LO+), 11 (LO-)
    # and an analog pin, 0 (OUTPUT)
    myAD8232 = upmAD8232.AD8232(10, 11, 8)

    ## Exit handlers ##
    # This function stops python from printing a stacktrace when you hit 

def SIGINTHandler(signum, frame):
        raise SystemExit

    # This function lets you run code on exit, including functions from        myAD8232
def exitHandler():
    print("Exiting")
    sys.exit(0)

    # Register exit handlers
    atexit.register(exitHandler)
    signal.signal(signal.SIGINT, SIGINTHandler)

    # Output the raw numbers from the ADC, for plotting elsewhere.
    # A return of 0 indicates a Lead Off (LO) condition.
    # In theory, this data could be fed to software like Processing
    # (https://www.processing.org/) to plot the data just like an
    # EKG you would see in a hospital.
    while(1):
        print(myAD8232.value())
        time.sleep(.001)
if __name__ == '__main__':
    main()

Answer 1

您可以使用ADS 1110或1115 n与覆盆子连接，将心率传感器的引脚连接到ADS 1110的A0引脚

覆盆子PI AD8232
