Hello..,
I have declared an array key0[3]={'1','A','B'}
and I want to put only one element of this array on my lcd every time that a==0x00,
so, I wrote:

if(a==oxoo) {
lcd_puts(key0[n]);
n=n+1;
};

But, Codevision program could not understand the second line of the above code...
Can you tell me the reason ..?
Thanks in advance... :!:

Quote:

every time that a==0x00

but your code is

if(a==oxoo) {

rather than

if(a==0x00) {

I think you want lcd_putc(). (or maybe it is lcd_putchar() )

You can put lipstick on a pig, but it is still a pig.

I've never met a pig I didn't like, as long as you have some salt and pepper.
