Raspberry PI AD8232

Question

我想編程一個使用Raspberry PI的AD8232心臟監視器，據我所知，我已經爲ump和ADC ads1115安裝了所有正確的軟件包。我遇到的問題是當我嘗試運行代碼時，我得到一個值錯誤： 文件「/usr/lib/python2.7/dist-packages/upm/pyupm_ad8232.py」，第170行，在初始化中 this = _pyupm_ad8232.new_AD8232（loPlus，loMinus，輸出，aref） ValueError：UPM無效的參數：無效的AIO引腳指定 - 你有ADC嗎？ 任何人都可以幫助解決這個問題，我正在使用的Python腳本低於 謝謝。

#!/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.

你可以使用ADS 1110或1115 n請與覆盆子連接，進行心臟速率傳感器的引腳ADS 1110

的A0引腳
