We're trying to get i2s output from the QCC3008. We can see analog output, but we don't show any i2s output. We used the ADK Config tool to apply the following:
Configuration Set:
- Audio:
- I2S:
- BPS: 16
- Resample rate: 48 kHz
- Voice: 48 kHz
- Bit-clock scaling: 32
- Output > Channel Allocation:
- Main Group Primary Left and Right: Hardware Endpoint Type: I2S
We tried to pull pin 29 SPI-PCM# low with a 1 kOhm and a 10 kOhm R, but neither worked. We noticed the pin is still high: we measure about 1.5V on that pin with a 1kOhm pull down to ground.
