c＃microchip mcp2200高CPU使用率

我有一個微芯片mcp2200設備。設備連接樹形按鈕（作爲數字輸入）。我用它作爲反饋機器。 machine schemantics
我將它附加到Windows Server 2003 x64。然後，我在我的C＃應用程序中使用了微芯片mcp2200驅動程序和Managed SimpleIO DLL。
在C＃中，我使用頻率爲500毫秒的時間來檢查按鈕是否被按下。在一兩個小時之後，服務器的CPU使用率一直很高。如果我殺了C＃程序，一切都好。我如何愛cpu使用？或者我的代碼有錯誤？

從一開始或一段時間以後，它是否具有較高的CPU權利？ – 2013-02-23 14:37:27

過了一段時間。 – Guntis 2013-02-23 16:36:29

然後附加一個調試器，它具有較高的CPU並將其分解，以查看引起問題的調用堆棧。如果高CPU進程也是系統，那麼它可能是芯片的設備驅動程序問題。那麼你應該看看更新的驅動程序。 – 2013-02-23 20:31:06

答案是：C＃應用程序重啓通過計劃作業每隔一小時。沒有更高的CPU使用率。
