Heello everybody,
I designed a PCB with an Atmel Samd21 (Pins are similar to MKRZero) which is supposed to play .wav files over the amplifier TAS5805 (connected by i2s). The .wav file is run by DMA (data from SD card).
Everything works fine and I can hear my selected sounds(user Input 'b'). But when I run a watchdog timer (user Input 'c') or sleep function (user Input 'x'), I can't hear my sounds after that, even when I disabled the WDT before again (user Input 'v').
I guess there are some troubles with the RT clock (code is still running properly, even after sleeping). Did someone have similar problems and knows how to solve it? I am grateful for every advice/approach.
Also I appended a test code. Maybe that's helpful to understand what I am talking about.
Thank you! [1](ผลบอลสด !! SIAMSPORT.TV รายงานข่าว ชมบอล ไฮไลท์ ทีเด็ดบอล)^
