PCM1808 frequency response and not working with internal ADC #1537
-
I have had i2s-12s working but I noticed a 6db/octave rolloff. I ran the SineWave gen to prove if it was the DAC PCM5201 or the PCM1808 were the problem was occuring. The output with the sineWave gen shows very flat response from 100Hz to 10Khz, I didn't bother to test higher. I then thought I would pump a signal via the internal ADC (esp32) and see if that was also flat. Unfortunately I've hit a problem with ADC in to I2s out. I am using the example provided: // Arduino Setup // RX automatically uses port 0 with pin GPIO34 // TX on I2S_NUM_1 // Arduino loop - copy data From the Info messages I see this Anyone have any ideas if I have misssed something? Looks like the i2s driver is failing for some reason. I'm trying to get a hilber function working which is when I noticed the rolloff in frequerncy, if anyone has some ideas on this, I would love to hear them BR |

You messed up with the ports! Analog must be on port 0, so I2S can only be on port 1. |

You messed up with the ports! Analog must be on port 0, so I2S can only be on port 1.
But you left it to the default with is 0, which is already used, so you created a conflict!
