8 bit input checking

[dong sung]

hello all,
I have a 8 bit input at port B.(I pulled up port B to TRUE)This value is displayed on LCD.Now I want LCD to keep displaying "Dong the king" till it actually gets input at port B.I saw lotss of codes in this forum .help me.

My question --- how I check if I am getting 8 bit input?


int8 dong;
//I display"Dong the king"here
dong = input_b();
if(dong!=11111111)// THIS CORRECT WAY??I USED NOT 1111111 since port B is pulled up TRUE initially
{
//if PIC getting input
}

Sorry poor ennglish

Thanks,

sorry one more question:
Sometimes my LCd acts weird when I switch on the power and my 8 bit input is already connected.It shows blocks.

But when I attach input wires after LCD is powered on,it shows correct messages.Why is this?

Thank you all

If you're not using decimal, then you have to tell the compiler
what the number system is. This is done by putting "0x" in front
of the value for Hex, or "0b" for binary, etc.
