ISR error #76

Open kotopuz opened 4 years ago

kotopuz commented 4 years ago

Dear all,

Nodemcu with ESP8266 with dcservoESP_wifi.ino sketch. Motor turns on and off. I've checked encoder connections , connections to H bridge, power. Somehow I see this in serial monitor. Motor rotates a little then stops then again rotates.

Serial gives this:

rst cause 2 is due to Reset button being pressed or chip waking up from sleep mode. None of it seems to make sense in your case so ...

my guess is that is caused by a power supply problem on the ESP8266, try with a 2200uF/16V electrolytic capacitor between the 3V3 and GND rails.

I do not think it is code related. You can try with the sample programs (File/Examples/ESP8266) too see if these work ok or trigger a similar error too.
