Interrupt counts twice, FALLIING and RISING !
Posted: Sun Jun 18, 2023 6:42 am
Hi,
I've a TTGO T3 module and have programmed with the Arduino IDE.
I use 2 pins on which I attached interrupts with FALLING edges.
I count the interrupts and see that the ESP32 counts both FALLING and RISING edges.
I debounced the input by software and hardware, but there is no solution.
I tried to changed pins, internal or external pullups, etc... No way.
It clearly counts each edge !!
I suspect a bug somewhere.
Has anyone else noticed this weird behavior ?
Thanks,
