This program sets up EVA Timer 1, EVA Timer 2, EVB Timer 3 and EVB Timer 4 to fire an interrupt on a period overflow. A count is kept each time each interrupt passes through the interrupt service routine.

This experiment uses the Blackfi n BF533/BF537 EZ-KIT to run a simple FIR fi lter on stereo channels at a sampling frequency of 48 kHz. The CYCLE register is embedded in the main program ( process_data.c) to benchmark the time needed to process two FIR fi lters. A background telemetry channel (BTC) is set up to display the cycle count.

This example uses a timer to generate interrupt at a specific period. The timer event handler increments the event count and prints in stdout.

1、用feng模塊將選手按下按鍵信號輸出高電平給鎖存模塊lockb,進行鎖存的同時發出aim信號實現聲音提示,并使count模塊進行答題時間的倒計時,在計滿100妙后送出聲音提示; 2、用ch41a模塊將搶答結果轉換為二進制數; 3、用sel模塊產生數碼管片選信號; 4、用ch42a模塊將對應數碼管片選信號,送出需要的顯示信號; 5、用七段譯碼器dispa模塊進行譯碼。

Most satellite dish actuators send a series of pulses to indicate their position. By counting pulses the positioner knows where the dish is pointing. It is possible to use a serial port and Linux with RTAI patches in order to count these pulses, thus minimising the external hardware required for a positioner. The zip contains instructions, circuit diagrams and example code.

已知數據文件IN.dat中存有200個四位數,并已調用讀函數rData()把這些數存入數組a中,請編寫函數spellNum(),其功能是:把個位數字和千位數字重新組成一個新的二位數(新二位數的十位數字是原四位數的個位數字,新二位數的個位數字是原四位數的千位數字),以及把百位數字和十位數字組成另一個新的二位數(新二位數的十位數字是原四位數的百位數字,新二位數的個位數字是原四位數的十位數字),如果新組成的兩個二位數一個是奇數,另一個為偶數,并且兩個二位數中至少有一個數能被17整除,同時兩個新數的十位數字均不為0,則將滿足此條件的四位數按從大到小的順序存入數組b中,并要計算滿足上述條件的四位數的個數count。最后main()函數調用寫函數wData(),把結果count以及數組b中符合條件的四位數輸出到OUT.dat文件中。

Collection of key-value pairs. TDictionary represents a generic collection of key-value pairs. This class provides a mapping from a collection of keys to a collection of values. When you create a TDictionary object, you can specify various combinations of initial capacity, equality operation, and initial content. You can add a key that is associated with a corresponding value with the Add or AddOrSetValue methods. You can remove entries with Remove or Clear, which removes all key-value pairs. Adding or removing a key-value pair and looking up a key are efficient, close to O(1), because keys are hashed. A key must not be nil (though a value may be nil) and there must be an equality comparison operation for keys. You can test for the presence or keys and values with the TryGetValue, ContainsKey and ContainsValue methods. The Items property lists all count dictionary entries. You can also set and get values by indexing the Items property. Setting the value this way overwrites any existing value. The class TObjectDictionary inherits from TDictionary and provides an automatic mechanism for freeing objects removed from dictionary entries.
