为什么我的控制台程序可以连接g29滚轮,但无法读取滚轮数据?

我正在使用G29在VS2017中构建驾驶模拟器。官方演示可以正常运行。但是我的代码只能使LogiSteeringInitializeWithWindow()和LogiUpdate()返回“ TRUE”。 LogiGetState()和LogiGetStateENGINES()无法返回任何数据。

我已经阅读了SteeringWheelSDKDemo的代码,但是什么也没找到。对于g29车轮,谷歌搜索太差了。

#include <iostream>
#include <stdio.h>
#include "map"
#include "string"
#pragma comment(lib, "LogitechSteeringWheelLib.lib")
#include "LogitechSteeringWheelLib.h"


int main()
{
    DIJOYSTATE2 *controller_state = NULL;
    DIJOYSTATE2ENGINES  *last_state = NULL;
    std::map<std::string, int> current_state_map;
    int controller_idx = 0;
    HWND h_wnd = FindWindow(_T("ConsoleWindowClass"), NULL);
    while (!LogiSteeringInitializeWithWindow(true, h_wnd)) {
        printf("try again.\n");
    }
    while (true) {
        if (!LogiUpdate()) {
            continue;
        }

        while (LogiIsConnected(controller_idx)) {
            std::cout << LOGI_MAX_CONTROLLERS << std::endl;
            wchar_t deviceName[128];
            LogiGetFriendlyProductName(controller_idx, deviceName, 128);
            std::cout << deviceName << std::endl;
            std::cout << "wheel " << LogiIsDeviceConnected(controller_idx, LOGI_DEVICE_TYPE_WHEEL) << std::endl;
            std::cout << "Joystick " << LogiIsDeviceConnected(controller_idx, LOGI_DEVICE_TYPE_JOYSTICK) << std::endl;

            controller_state = LogiGetState(controller_idx);
            last_state = LogiGetStateENGINES(controller_idx);
            std::cout << "-------------" << std::endl;
            std::cout << controller_state->lX << std::endl;
            std::cout << controller_state->lY << std::endl;
            std::cout << controller_state->lRz << std::endl;
            std::cout << "-------------" << std::endl;
            std::cout << last_state->lX << std::endl;
            std::cout << last_state->lY << std::endl;
            std::cout << last_state->lRz << std::endl;
            std::cout << "-------------" << std::endl;
            system("cls");

        }
        std::cout << "unconnected\n";
    }

}

我希望会有wheel的数据,但是它是0。
