#59665 Hi,
can someone point me to a location, where a 4x4 keypad connection to esp8266 12e is implemented with native sdk? I am using eclipse and implement this integration with the native sdk.

Thank you.

There's no embedded function to handle matrix keypads, you should deal with the keypad with GPIO functions.
You can check the keypad by pooling or by interrupt.
Interrupts are available in all GPIO pins, so, you can install interrupts to detect key presses.
