hi everybody, i was trying to create a keyboard application for psoc, i'm basing my design on the Keypad_v1_0 that works with 2 LUT and 1 status register,in my case the LUT component have a maximum of 5 inputs and i need 6 inputs so i'm implementing logic gates arrays and boolean logic to fix them, but i'm having some issues reading the rows and the columns, the columns 1,3 and 5 is working fine, but the columns 2 and 4 doesn't work properly.

I have got a pure software solution for that. A bit old, you'll need to polish it up a bit (update components), but might help you.

Have a look here...
