Other Parts Discussed in Thread: CC3200, CC1352P7

Hi,

    I have LP-CC1352P7-4 launhpad, for which i have mounted BOOSTXL-AUDIO, and made connection changes as per I2S echo example given 

https://dev.ti.com/tirex/explore/node?node=ADgQkBnE1H5pEBm2TFEl3A__fc2e6sr__LATEST

There are bending of pins recommended as below : 

CC3200 Audio BoosterPack

  • The BoostPack’s DIN signal pin is not compatible with this LaunchPad. Use one of the following modification(s) to enable the CC3200 Audio BoosterPack’s usage with the i2secho example.
  • Bend down the two pins below DIO30. Additionally bend down DIO28-30. Be sure that the bent pin(s) do not make contact with the IC or any other component, bend them enough to make sure they don’t connect to the CC3200 Audio BoosterPack.
  • Attach the CC3200 Audio BoosterPack to the LP_CC1352P7_4

Till this portion, i got it connected , but below ones i am unable to find and locate them.

  • Run jumper wires between the following pins on the CC3200 Audio BoosterPack:
    • DIN: P3.3 and P3.9
    • DOUT: P3.4 and P3.10
    • BCLK: P3.5 and P3.8
    • FSYNC/WCLK: P4.9 and P3.7
  • See Audio BP User Guide, Figure 2-1 for information on where these pins are located.
  • See below for a diagram.

I tried flashing I2S echo audio example, i am unable to get echo back of audio .

Can you please help.
