First thing you should do is go to the Microchip website and search their
application notes section for PWM and/or 12F675 related notes. PWM is
really not that hard once you look into it. Get the Ap Notes and then
get back with me.

hello,
thank you for the replies,this is my very first project in my
final year B.E and i am quite o.k with 8085 programming . i
downloaded the data sheets a little time ago.i have gone through the
data sheets.
we are actually first working on PWM rght now.....we r using timer0
for on time and timer1 for off time .problem is mainly with timer1
because it is 16 bit. i have no idea about pic programming.
maybe if i get an example...i can get an idea for starting .
i am running short of time because i had my exams and hardware took
a lot of time.
i just want a brief idea of how to about programming a pic....
can u please illustrate a simple pic program ( of the same
pic12f675)?

Look at application notes AN863, AN874 & AN250 on the mocrochip web
site.

AN863 has great examples of timer & interrupt usage, math examples
etc. in master.asm. Mux.asm uses the 629 which is a 675 without the
ADC.

AN874 specifically uses the 675. Examples of ADC, timer and pwm
operations.

AN250 is another example using the 675.

Do not just look at/for examples specifically using the 675. Most
code for any of the mid-range 14 bit mcu's can easily be ported to
other variants of the 14 bit core. All are examples of how to get
started.

I have just finished a 12F675 program, if you just want something to
look at.
