我想從Python調用DLL中的函數(shù)。但我有個錯誤："Attribute Error function not found"

這是我的代碼：import os

import ctypes

os.chdir("C:\\Program Files\\Compact Automated Testing System V2.0")

# Load DLL into memory.

CATSDll = ctypes.WinDLL ("CATS.dll")

# Set up prototype and parameters for the desired function call.

CATSDllApiProto = ctypes.WINFUNCTYPE (ctypes.c_uint8,ctypes.c_double)

CATSDllApiParams = (1, "p1", 0), (1, "p2", 0),

# Actually map the call (setDACValue) to a Python name.

CATSDllApi = CATSDllApiProto (("setDACValue", CATSDll), CATSDllApiParams)

# Set up the variables and call the Python name with them.

p1 = ctypes.c_uint8 (1)

p2 = ctypes.c_double (4)

CATSDllApi(p1,p2)

但DLL文檔顯示了一個以ChannelId&amp；DAC Voltage為輸入的函數(shù)setDACValue。

以上是基于StackOverflow提供的一段代碼。

我還嘗試了使用cdll.LoadLibrary然后調用函數(shù)的簡單方法，但這也會產(chǎn)生相同的錯誤。

有人能告訴我怎么了嗎？謝謝。
