TMS320C5515: how to run the Digital Stethoscope MDK on EVM5515

Part Number: TMS320C5515

hello,

I am trying to run the demo application of document called ' Digital Stethoscope Implementation on the TMS320C5515 DSP Medical Development Kit (MDK)' on EVM5515 board. The link of this document is http://www.ti.com.cn/cn/lit/an/sprab38a/sprab38a.pdf . I have 3 questions:

1,In the document, the FE board is AIC3504. I cannot find any place to buy this board. Please help.

2, this document is very old as it was using CCS3.x. Does the Stethoscope MDK have a newer application note?

  • Hi,

    1. I think it is best to ask this first question in the Audio Converters forum: e2e.ti.com/.../64

    2. No, I am afraid there isn't a newer version of this document, however you should be able to compile the sources with the latest versions of CCS.

    Best Regards,
    Yordan

     


     Please make sure you read the forum guidelines first.

    Hello Yordan,

    Thanks for your prompt reply. I tried to compile it with CCS4.x. But errors shows up. Do you mean it is compatible with latest version of CCS?
  • In reply to Yordan Kovachev:

    Besides, for better understanding the code, could I get:
    1, Register Manual of C5515?
    2, CSL API Manual as it is not the version of the one I found in website (www.ti.com/.../sprc133)
    3, source code of system_drv.lib, sar_drv.lib, i2s_drv.lib and dma_drv.lib?

    Yang,
    Please find the CSL API documentation once you have installed the CSL at C:\ti\c55_lp\c55_csl_3.07\doc
    The technical documentation for the C5515 is located at www.ti.com/.../technicaldocuments there is the device datasheet that shows the register info www.ti.com/.../tms320c5515.pdf

    Hi

    I am trying to run the stethoscope example case on AIC3204+5515. That means no need FE board in the application note. 

    I modified below:

    1, initialize 3204 thru function AIC3204_init(); Configure it as (<-> Microphone --> to HP)

    2, change from I2S0 to I2S2 in CSL_I2S_Configure  and CSL_DMA_RequestChan function;

    3, change the DMA address to I2S2 address. DmaConfigRcvL.srcAddr = 0x2A28; DmaConfigRcvR.srcAddr = 0x2A2C; DmaConfigXmitL.destAddr = 0x2A08; DmaConfigXmitR.destAddr = 0x2A0C;

    For this, I should hear the sound from Headphone out pin of EVM5515 board. But it failed.  

    pls help.
