RE: PWM using microcontroller (pic)
I'm not doing any cut'n paste. If what you want is stay with what you know and don't intend to help the global research to go forward, then keep on this way.

I don't like your attitude and will keep my ideas to help someone else.

Smile!

RE: PWM using microcontroller (pic)
I still don't like your attitude neither your cynical criticism regarding my attempts of taking your project somewhere else than a being plain peace of gear. Your project is not interesting. Neither you.

Ciao ragazzo!

RE: PWM using microcontroller (pic)
My ideas are not big, they are incomplete.. and I cant achieve anything as technical as the things you make, and let me tell you I'm really admirative. Same for you.. what you make may never be complete, as you might sometimes have the use of a little man..

BTW: Get a better Italian translator.. Ragazzo means "good looking".

Zipstor.

I've finally all but worked this out. You are obviously one of 4 things.

a. An extremely clever, very gifted, 8 year old
b. An above average 10 year old
c. A normal 12 year old, or
d. a stupid teenager

If the correct answer is d, then I will, in future, allow for your hormone imbalance being the cause of your problems (not)

I'm also betting, from some of your posts in other threads, you were a Kamikaze pilot in a previous existence.

You are living proof that a little knowledge can be a dangerous thing.

Being compared to a kid is okay for me. As it's important to keep a connection with childhood. Have fun.

Definitely answer 'd' then. Don't bother responding. Any future postings from you will be ignored.

RE: PWM using microcontroller (pic)
Great job BENNY:
I is going to adapt this circuit to an O2 temp sensing switch unit i have been working on. Thanks for the HEX code for the Pic..... This unit will be using DDPS instsead of pots to calibrate most everything.. Already have a beta with an A/d converter coupling into my laptop via usb 2.0 . Bench unit , so far works otay ..Your circuit might be a neat addition to this .. Also just posted a more tried true version of O2 sensor manipulation with temp sense switching on me website. http://www.freewebs.com/mobilehydricity would like to toss your circuit in with this one , intergrate if you will and simply add the DDPS in place of all the control pots in the circuit with a rs-232 i/o insted of usb-2.0. Thanks for a neat circuit and software. MIKE

You're welcome to use any of the circuits I posted either as stand-alone as is, or modify to suit your own requirements. The circuit you have displayed on your web site is an early version of the circuit, The latest version does most of the PWM control in software, using only a single inverter as external logic to the pic. Which version you want to use?

The inputs from the pots are set to operate from 0-5V, and the program is set to set up the PWM outputs using this range. As long as your modifications maintain that relationship, the dual PWM will work ok.

Note that there is a lot of spare capacity in the microcontroller. There are a number of spare ADC available, so there is room to add feedback for auto control of the PWM, but this would require additional coding for the pic firmware, as would parameter output to LCD display units. etc. Serial I/O is also possible using this particular pic. Have a look at the datasheet for same, 18F452, available from Microchip web site.

The existing, very basic, firmware was written using Proton Development Suite (PDS, http://www.crownhill.co.uk) which uses a subset of Basic programming language.
If you need any assistance with any firmware mods to accommodate any part of your circuit, feel free to contact me.

AS I INDICATED, THE CIRCUIT WAS AN TRIED TRUE VERSION OF AN EFIE.. I lile having the extra room on the pic .. The beta version I designed is pretty simple using a pic and some DPPs, as both the comparator and adjusting mech. Get back to shortly ..Again Good Work. MIKE
