  or if you haven't enough patience for that, try software pwm in Jal for
16F84, or hardware pwm for 16F87x.

include 16f84_4
include jpic
include jdelay

var bit led is pin_b7
pin_b7_direction = output
var byte pulse = 1

forever loop
  delay_100us ( pulse )
  led = high
  pulse = pulse + 1
  delay_100us ( 255 - pulse )
  led = low
end loop
