WDT Error and following automatic Reset

[rudydevolder]

• Arduino board: Feather Huzzah
• Arduino IDE version (found in Arduino -> About Arduino menu): 1.6.10
• List the steps to reproduce the problem: Just running the standard steppertest.ino example with more steps in one run

I found the solution already see: [https://github.com/esp8266/Arduino/issues/2377 ] By adding in the library-code the delay(0) command.: *

  while (steps--) {
    //Serial.println("step!"); Serial.println(uspers);
    ret = onestep(dir, style);
    delayMicroseconds(uspers);
    //Rudy De Volder: to solve WDT problem with the ESP8266 simply add the following line:
    delay(0);
  }

A similar issue on my Feather Huzzah / motor shield is present. I hope your patch fits also my HW!

According to: https://github.com/esp8266/Arduino/blob/master/doc/reference.md#timing-and-delays you might also consider to replace the

delay (0);

by

yield();

I will try later today... and let you know.

ok added a yield, please tr it!

I checked both delay (0); and yield (); ==> both are working for me. Thanks for adding the yield function.
