Re: External 24bit I2S ADC nor working
The ADC is not getting an input signal. Since the ADC has a S/N of about 100dB I would expect a low noise output.
I already tried to convert from unsigned to signed:
But then I also get strange output values.

Garbage output from external i2s ADC
Hello, I have connected an external 24bit I2S ADC (CS5341) and I only get random data from the device. I tried both master and slave mode and different samplerates but I always get random data. I have checked both the LRCLK and BCLK in master and slave mode and they are present. This is my initializ...
