Five different types of interrupts can be programmed. When the corresponding criterion

5種不同類型的可編程中斷。當(dāng)相應(yīng)的(中斷)準(zhǔn)則有效時，中斷引腳被一個高電平觸發(fā)。所有的中斷準(zhǔn)則都是相結(jié)合的（combined ），而且可以用布爾<OR>條件來（ Boolean <OR> condition）驅(qū)動中斷緩沖器。$ o3 r% T3 _% y. l/ r' h

中斷準(zhǔn)則使用的數(shù)字代碼來自數(shù)字濾波器輸出。因此所有閾值的設(shè)置都由量程選擇開關(guān)來界定（section 3.1.3.2 ） 。用于高加速度和低加速度之間的去抖timiming是絕對值（ HG_dur和LG_dur寄存器的一個最小可分辨信號（correspond to）相當(dāng)于1毫秒， timiming的準(zhǔn)確性于振蕩器精度成正比= + / -10 ％ ） ， 因此，它并不依賴于選定的帶寬。用于motion中斷位和alert規(guī)則的timiming正比于帶寬設(shè)置（section 3.1.3 ）

這是本人接的一個翻譯活,不算什么機(jī)密,共40頁,但是還沒翻完,先看十頁吧.發(fā)出來就是讓大家看看mens系統(tǒng)的陀螺儀是怎么工作的!!!有興趣的話,可以十天后下我的完整版的數(shù)據(jù)表!!! |

樓主
請問樓主你的翻譯啥時候能出來呀，謝謝！
在此謝過老兄啦。, @( x1 o7 L, S1 x
