It's the first time to light Led lights with Keil Vision 3 software. How to write the program?

Take 5 1 single chip microcomputer as an example.

The LED is connected to the P 1.0 port.

sbit led=p 1^0；

{

LED = 0； //Initialize the LED to OFF.

while( 1)

{

LED = 1； //light the LED.

}

}

end

The most important thing is to look at your hardware
