Confused mode in connecting the DSP and Arduino

David Sly

Hi Everyone,

I have got a typical question here for you.

I am using Arduino which is then connected to DSP c5515 usb stick. I am using code composer 5.0 version to connect the code through Arduino to the DSP. Initially i have performed some UART tests to conclude that something was working and was successful in getting the echo back to the console.

Now i want to test the tone(sound). Am using aic3204 to do that. but i want DSP to identify the inputs given by me and then play a tone simultaneously. 

Do I need to connect(combine) 2 projects to get the desired result? 

Note: I know that i can use just DSP by itself for the tests. But for some reason my DSP seems not responding well. Hence i started using Arduino using the Serial IO with C coding thru Arduino. Now i want to do the same thing for the Tone recognition.

    Hi,

    Team will work on this to let you know the update on the same.

    Thanks & regards,

    Hello,

    Yes, it sounds like you will need to combine two projects for UART communication and I2S communication.

    Start by studying the CSL examples. http://www.ti.com/tool/sprc133

    Play close attention to the EBSR pin mux configurations in the examples.

    What do you mean by the DSP seems not responding well? In JTAG? UART? I2S?

    Maybe you will find the C5000 Teaching ROM examples interesting - there is one example that uses the Goertzel algorithm for tone detection. http://e2e.ti.com/group/universityprogram/educators/w/wiki/2033.teaching-materials.aspx

    Hope this helps,
    Mark
