• PLL issues with ADSP-21479 EZ-Board

    Hey there,

    we got an ADSP-21479 EZ-Board. As we want to do some profiling/benchmarking, we want to make sure that the processor is running it a relatively high clock frequency.

    The debug output of the bootloader located in NAND flash is:

    *** 21479…

  • Simulating ADSP-21479

    I am trying to simulate an app on the ADSP-21479.

    I don't need any real-time I/O so simulation is fine.

    I have tried both CCES_runner and chipfactory.

    Here are the outputs :

  • [Ask] ADSP-21479 & ADSP-21584 OrCAD Symbol (Library)

    Sir,

    Do you have ADSP-21479 & ADSP-21584 OrCAD symbol?

    If not, could you help export EZ-kit's file then it can be imported to OrCAD.

    My customer uses OrCAD and need the symbol library.

    Thank you,

    Kris

  • ADSP-21479 UART中断方式发送数据问题

    使用ADSP-21479 UART发送数据时,遇到一问题,看了好久也没能解决,希望大侠能帮忙看一下。

    1、IDE: CrossCore Embedded Studio 1.1.0

    2、处理器:ADSP-21479

    3、工程及代码参见附件。

    4、具体描述:

         使用UART0发送数据,波特率115200,8位数据位,1位停止位,无校验。

         使用DMA方式发送数据时,可以正常进入发送中断函数UART_tx_isr。

         使用普通中断一个字节一个字节的发送数据时,则不能进入中断函数UART_tx_isr…

  • 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…
