keyboard selection


Hi, I use a keyobard library to control keyboard, but i use only 8 pin for keyobard for 16 keys max, (from COL0 to COL3, and from ROW0 to ROW3) and I want use ROW4 in I/O use and exactly with output but the module send me at subscription of pin that the pin is already subscribed, because is present in keyboard library from AT+cmer=,1 in library.
Is possible, to select only specific pin to keyboard and other to dedicate for input output ?

Thanks :open_mouth:


Problem solved,
when use keyboard library, all pin ROWx and COLx are reserved for keyboard, and then this pin not is free for other application.

Thanks at all
