Other Parts Discussed in Thread: BOOST-CCEMADAPTER, CC2564C, CC256XQFNEM, CC3200AUDBOOST, CC3200
Hello,
I want to set up an AG HFP Demo with:
- MSP432P401R (launchpad)
- Boost-CCEMADAPTER
- CC256xQFNEM with CC2564C
- And the CC3200audboost
I use "Code composer studio" to download the AG HFP Demo to the launchpad.
Over the UART I configure the board and setting up an HFP connection with my HF. The HFP gets properly set up.
The issue I have is that the CC3200audboost doesn't generate audio for CC2564C. It as well doesn't sample the data it gets from CC2564C. There is a clock and fsync visible, plus the data from CC2564C which it got from the HF.
I tried to debug with code composer studio through the code, I tried as well to change the input source from "CODEC_ONBOARD_MIC" to "CODEC_LINE_IN". Still no data on AUD_OUT. As source for Line_In I used PC soundcard (Vin max ~700mVp).
I configured everything like described in user guide: Getting Started Guide for MSP432 + CC2564C
Summary: HFP is working, but CC3200audbost doesn't generate audio for PCM/I2S interface
In the following scope plot you can see the PCM/I2S signals. CLOCK, FSYNC and AUD_IN are toggeling, AUD_OUT is 0. Strange is as well that CLOCK and FSYNC are the same. I always thought with FSYNC you can chose channel, i.e. left and right, which would mean i.e. for 16 clocks fsync low = chan 1, for 16 clocks fsync high = chan 2...
Any idea why my CC3200 is not running?
Thanks
Joel
