python调用dll相对而言比较方便，写个脚本调试轻松工作，快乐生活。

python脚本

from ctypes import *
import time


# 脚本挂起
input()

# load dll __stdcall 方式
dll = windll.LoadLibrary('IDPSOLID510Lib.dll');

print("dll handle=",dll);


#获取版本号
p_version = create_string_buffer(512);
ret = dll.get_version(p_version);

s = string_at(p_version,-1).decode('gbk');

print("ret=",ret," version= ",s);

# 调用结果例子
# ret= 0  version=  model: CardScriptComplier | version: v1.0.1.20180214

# 枚举设备
ret = dll.EnumDevice(p_version);

# 连接设备
ret = dll.ConnectDevice(p_version);

print("\nstart ==")

for i in range(15):
    print("--------count index: %d --------" % (i+1))
    # 进卡
    ret = dll.MoveCard_In(p_version);
    ret = dll.MoveCard_RF(p_version);

    # 模拟洗卡过程
    time.sleep(6.5)

    # 出卡
    # ret = dll.MoveCard_Out(p_version);
    ret = dll.MoveCard_OutBack(p_version);

print("end ==")

# 关闭设备
ret = dll.DisConnectDevice(p_version);

# GetDeviceInfo
# GetDeviceStatus
# 
# MoveCard_OutBack
print("ret=",ret);
