Hello everyone,
Problem :
I used the same pins no. for the keypad for Teensy 3,2 and 4, when I connect the keypad to Teensy 3,2 it works fine, but when I connect it to Teensy 4 it displays an automatic number that I did not press. I use the same Cable.
I have checked (R1,R2,R3,R4,C1,C2,C3) the keypad and Teensy 4 with a multimeter and the signal is OK (e.g. when I press 1, R1 and C1 make contact).
What should I have to check?
Thank you in advance and I await your reply.
Regards
Sandip
