HELP use 31 pads * 4MUX but the flashing LCD shows SPLASH1. can't press any buttons

[attachi201]

Hi i use 31 pads but the flashing LCD shows SPLASH1. can't press any buttons, but when i comment code scan mux SENSING & SENDING MIDI So it works
i use Mega2560 with 4*MUX IC and EEPROM MUX LCDI2C code this is my code

Hi, did you fix the problem? Thanks

[RyoKosaka]

If there is nothing connected to the analog or MUX pins for sensing (floating pins), it will pick up noise and be perceived as a continuous hit. Connect a pad to all the pins, or if not, use a 1MΩ resistor to connect them to GND.

[attachai201]

@RyoKosaka You're right, the code can now be used, thank you very much.

[attachai201]

@jhsa Now it works. But you have to connect all pads to the board.

[dairyleaDunkan]

Can the MUX chips be daisy-chained or is it better/faster to have them run separately like in the poster's code?
