I2S & WDTZero

[CptHolzschnauz]

I have also (clock?) problems with I2S (Not I2C!) with HARD and SOFT.

I2S.read(); is just not working with a watchdog enabled. Without Watchdog it's working.

Hardware: Arduino MKR 1400, MEMS Micro on I2S
Software :
#include <I2S.h>
I2S.begin(I2S_PHILIPS_MODE, 16000, 32);
I2S.read();

Thx a bunch for coding this lib!

I had the same behaviour with sd data copy and copy data from the modem memory.
I think it's all related to the blocking clear function,
the PR #8
brought no remedy but there must be a bug.
When i run my function in setup() before initialize the wdt software watchdog, everything works smooth.

arduino/ArduinoCore-samd#474 solves the problem. It's not this lib.
