Re: playing mp3
Hi Panno,
do you observe the spikes in a setup with an external I2S-D/A-audio converter or are you using the internal D/A conversion at pin25?
Only with the internal conversion I can see/ hear this in my setup. May be because the Output pin is set to Vss/2= 1.6V as soon as initializing the analog output for playing the MP3.
If the output goes to a headset etc a serial 100nF condensor as high-pass can help.
