How do I fade in and out A Led, on the Propeller Chip

TrickyOne

What I want to know is how do I fade in and out A led on Propeller Chip. How do you make the code for that?

Search for "pulse width modulation" PWM

I believe there is a section devoted to just that in the Propeller Education book...

Start with PWM duty set to 0 and ramp it to 100. Use the object called PWMASM, it has a set duty method. Create a loop that repeats, increment the Duty by 1 each repeat. Use waitcnt to determine how fast it gets from 0 - 100.

PUB RampLed
  x := 0
  Repeat 100
    pwm.setduty(x)   'set pwm as pwmasm  object
    waitcnt(40_000_000 + cnt)
    x++
