c# - 罗技的 LED 照明 SDK 不适用于我的 G502

Question

我正在尝试获取 Logitech's own LED SDK使用我的 G502，但我不能。我使用的是 SDK 版本 8.82.7，这是目前最新的版本。我在 SO 或互联网的其他部分也找不到任何东西，所以我在这里问。

这是我的 LogitechGSDK.cs:

using System.Collections;
using System.Runtime.InteropServices;

我的变色代码基本上是

LogitechGSDK.LogiLedInit();
LogitechGSDK.LogiLedSetTargetDevice(LogitechGSDK.LOGI_DEVICETYPE_ALL);
LogitechGSDK.LogiLedSetLighting(255, 127, 0);

哪个应该将鼠标的 LED 设置为漂亮的橙色，但实际上什么也没做。值得注意的是，包含在 SDK .zip 中的罗技自己的示例不起作用。我可以使用罗技的游戏软件设置 LED 颜色，但这不是我想要的。

罗技的SDK是不是坏了？如果没有，我该怎么做才能让它发挥作用？

编辑:我应该提一下，我确实拥有 G502 的 RGB 版本。

Answer 1

在您的代码中，LogitechGSDK.LogiLedSetLighting(255, 127, 0); 的参数不正确，因为它们超出了值限制。

它们应该是百分比而不是 RGB 值。

输入一个 0 到 100 之间的数字以使其工作。

同时替换您的代码:

LogitechGSDK.LogiLedSetTargetDevice(LogitechGSDK.LOGI_DEVICETYPE_ALL);

与:

LogitechGSDK.LogiLedSetTargetDevice(LogitechGSDK.LOGI_DEVICETYPE_RGB);

或者一起删除。

这里是橙色的例子:

LogitechGSDK.LogiLedSetLighting(100, 30, 0);

记得给代码足够的时间来初始化。
