hw_timer fires every +/- 800ms without arming
Posted: Sat Feb 09, 2019 3:20 amI have a project (https://github.com/jeroenst/espMQTT) which is using the hw_timer for dimming a light bulb.
But the hw_timer isr is also called without being armed by my own code, approximately every 800ms.
I searched through the esp8266 arduino library but I can't find any code which is using timer1 except for Tone.cpp core_esp8266_waveform.cpp. I also red that PWM is using timer1. But none of these am I using in my code.
How can I find out what is arming the timer1?
