Re: Single interrupt trigger performing callback function several times.

Thanks for the feedback. I did exhaustive tests with internal and external pull up and pull down resistors and none of the pins were 100% satisfied (they start well but sooner or later they perform the callback function 2 or 3 times with a single trigger).

ESP32 and LCD (4-bits and I2C Interface)

Through https://github.com/HexVitor/ESP32 you can find MicroPython modules for communication between ESP32 and HD44780 based LCDs. There are modules for 4-bits or I2C communication.
