need some programming help?
can anyone give me a breakdown of this program it is not something i'm familiar with. looking for a line by line break down and the end result
#define reloff PRT1DR &= 0x7f
char a=-20;
void main()
{
while(1);
{
a++;
if(a=10)
a=290;
if(a>1000)
a=0;
}
reloff;
Inv_Start();
LCD_Start();
LCD_Position(0,0);
LCD_PrCString("System ok");
@vmanes thanks bud last time i had anything to do with programming the lines of code were numbered. can anyone tell me more about the other commands like whats
#define reloff PRT1DR &= 0x7f
a function with something multiplied by zero
and whats
Inv_Start();
LCD_Start();
I'd be ashamed to admit I was familiar with something this bad.
while(1); //loop forever
{
a++;
if(a=10) //keep setting a to 10, and yes, it evaluates as true
a=290; //set a to 290 why?
if(a>1000) //never be true
a=0; //so a never gets set to 0. Wouldn't matter, as it'll be 10 again at top of loop
}
