dim a led

[fred.pacc]

hello, I would like dim 2 leds with a 16f628 and I wanted to know which function to use but if I use the function pwm the program is very slow

Then you may try the Hpwm function (only one) or write your own pwm that is faster then.

pwmxl:
           if cntr = 0 then outputport = 1        'this clears all pwm ports
           if cntr = dutycl then outputport = 0  'this line can be repeated for as                                                                                                                          
                                                             'many as you have pwm outputs
           cntr = cntr + 1
           if cntr = 0 then exitpwm
           goto pwmxl
exitpwm:
           return

I hope the rest you figger out by yourselfs !
