This application report describes the use of Timer_A3 to decode RC5 and SIRC TV IR remote control signals. The decoder described in this report is interrupt-driven and operates a background function using specific features the Timer_A3. Only a small portion of the MSP430 CPU?s nonreal-time resources is used. Specific hardware bit-latching capabilities of the Timer_A3 module are used for real-time decoding of the IR data signal, independent
and asynchronous to the CPU. CPU activity and power consumption are kept to an absolute minimum level. The Timer_A3 decoder implementation also allows other tasks to occur simultaneously if required. The solutions provided are written specifically for MSP430x11x(1) and MSP430x12x derivatives, but can be adapted to any other MSP430 incorporating Timer_A3.
電視遙控器設計基於MSP430
熟悉VB的朋友對使用ActiveX控件一定不會陌生，眾多控件極大地方便了編程，但唯一的缺陷是不能動態加載控件，必須在設計時通過引用，將控件放置在窗體上。VB6.0已能夠解決該問題，只是幫助中沒有明確說明，并且沒有描述到一些關鍵功能，由于以前的版本中可以動態創建進程外服務：如果對象是外部可創建的，可在 Set 語句中用 New 關鍵字、CreateObject 或 GetObject 從部件外面將對象引用賦予變量。如果對象是從屬對象，則需使用高層對象的方法，在 Set 語句中指定一個對象引用：
