Hi
I have a problem with a code in 8051.

I must use 6 switch with instructions.
The 1º fisrt one, when i press 0 i must put a letter in LCD display.

This code does not work like i want

SETB P2.0 (define the switch)
inst1: JB P2.0, outra
MOV P1, #'N'
SJMP inst1
outra: MOV P1, #'S'
SJMP inst1

But the button (switch) doesn't do anything...

Thanks
