Is there a option to connect a keypad to a industruino? I think the problem is because the industruino use Indio.digitalRead and not digitalRead.
thank you in advance
Hi, you can connect an Arduino-style keypad (8 pins) to an Industruino PROTO, as it provides direct access to the GPIO pins.
For interaction with an Industruino INDIO i would suggest to use the RS485 port, for example with a Nextion touchscreen as documented at https://industruino.com/blog/our-news-1/post/nextion-hmi-with-industruino-42 or you could get an off the shelf RS485 keypad. RS485 will allow you to use a longer cable length.

hello, thanks for you reaction. So if i can make up of you answer there is no way to connect a arduino style keypad to a industruino D21G. I will use it to make a new number to add for calling with the gsm module. Thanks you in advance Gérôme
