• ADSP-21479 片内RAM检测

         我需要对片内的RAM 使用MARCH C 算法 检测RAM,但是算法会破坏RAM内容,请问直接在main函数内检测会导致程序问题吗? 假如会的话,我应该在何处开始检测RAM ?

         一般都会在启动文件内添加检测,但是sharc处理器没有启动文件,现在我不知道我应该在哪里添加检测代码 。

  • RE: ADSP-21479 InitPLL Does Not Work Any feedback please?

    Hi,

    We recommend to refer EE-290 which provides example code for programming the PLL and discusses possible problems that can occur due to incorrect programming. Lastly, it provides debug techniques for correct PLL handling.

  • ADSP-21479 SPI 主模式的接收與發送

    請問使用ADSP-21479 的SPI,主模式的接收與發送該如何控制? "interrupt(,);" 如何使用?

    我有找到一些參考程式,測試硬體使用 ADSP-21479 + MCP3008 的 ADC。

    發現一些問題:

    1.測試發現SPI_CS會影響CLK,範例裡面沒有看到關於CS的控制指令。

    2.SPI無法持續動作,參考程式裡有用 "interrupt(SIG_P1, Master_Receive_ISR);",還有 "Enable_interrupt();",不太了解這個程式碼…

    Hi Anand, 

    Thanks for your reply, the asynchronous sample rate converter example is not available in the ADSP-21479 board support package. 

    I downloaded the example as part of the ASCR SHARC software module:

  • FAQ: Selective Booting of One Application from Multiple Applications using CCES for ADSP-21479

    The default boot kernel will load the application from sector 0. The requirement is to modify the boot kernel in a way that based on a condition (for example, the assertion of a flag input); it should load one of the two applications selectively.
