Ajay<contact@nospam.com> http://www.8051projects.net/forum-t9505.html HI AJAY,the trisio never show my GPIO 4 and 5 as input.i just cant understand why..my code ORG 0x00 BCF STATUS,RP0; MOVLW 00h ; MOVWF GPIO; BSF STATUS nicholastyc<thamyc_2000@nospam.com> http://www.8051projects.net/forum-t9505.html
