Hi Walter, I have been looking at this for some time now and keep coming back to this post. I am actually attempting to do a similar project to the tilt sensor project which you have built only on a...

Hi demon, I haven't had a chance to gt on the pc to try this yet but what would be the difference between using:

DEFINE OSC 4

And



Code:
@ __CONFIG _CONFIG1L, _PLLDIV_1_1L &...

Thanks, I shall try that when I am at home tomorrow evening!
Only the fact that I was always shown circuits with external ones! Are there many benifits to using the internal ones?
With the fuses...

Ahhh if only I had the brains and experience to think of that before bothering you lovely people!

So the 18F2550 chip i am currently using for some ADC work is doing something rather peculiar... I have it set on 10 Bit ADC and as far as i under stand this means i should get a response of 0-1023....

Sorry to drag up an old thread but i am struggling to get my head around these registers. I am moving over from using a 16F876A chip and at the moment i cant get the LCD to operate correctly. The...

Hi all, I have been struggling since converting from a 16f876A chip over to the 18f2550.

My problems start as soon as i go to program with PICKIT2 i get the error: "Warning: Some configuration...

Sorry I messed up the last bit there, my suggested code should of in fact read:

Perp = v - v0
Base = SQR((v1-v0)^2 - (v-v0) ^2)
Rad = Perp ATN Base

Also I believe the following to be true to...

So over a year and a half has passed and suddenly i am back in the same position i was in before. Due to personal reasons i had to drop out of the college course i was doing and now i am back on it...

Hi everone ive just been looking through the manual and trying to figure out a way to do an equation but i cant see anyway to do it within pbp!

The problem im having is i need to use inverse sin (...

Thanks again!
I shall try my best to have a play with this over the next few weeks.... Ive got my college project to work on first though!

ok that sounds like a pritty good idea and somthing i hadnt even considered!

So just a simple 555 timer switching a transistor to the laser with the pic at the reciever with a rang of if signal is...

Ive been having a long think about this. I ripped an old laser quest set apart that i had from when i was younger and did a bit of research into how they worked and IR does seem to give a deffinet...

Its down to the indidual servo buddy, the experiances i have had is the nice and cheap servos have alot of start up movement.... I got a cheap load of servos from ebay and they all have this problem....

Cheers for that flipper, I shall try that when I get back from the business trip I'm on.
Anything to make it simplier will help with the two servo motors!

Well the idea of the project is for a local paintball site. They are planning a MILSIM event in august and they wanted somthing to simulate a laser designator for their "airstrikes". So the idea was...

Awesome i was hoping it would be the case as the two run on very similar wavelengths!

Any suggestions on this one? I dont need to transmit much code probaly just the standard 2,# or somthing.
...

Hi there, I'm looking at using lasers to transmit some data. Would it be possible to use a laser to transmit a serial code to a IR reciever?

Cheers Chris

Well the speed control didnt take very long at all to implement so I have attached a fully working code below.

Now i have to wait for the servo motors i have ordered to arrive from HK before i...

Well i carried on with some work before checking back to this forum and i have a much more effective code now :) although i shall try some of the comments you made last Ace :)

Ive gone back to...

Thanks for all the replies i shall try and go through them now :)
Firstly i understand that the ACDIN can give the range from 0-256 how ever the accelerometer is not capable of giving a value of...

Nope this results in the servo panning uncontrolled trying to pass its limits. I havnt ever used a while loop before but assumed the piece of code you gave me should of fitted in where my current...

Hi guys, I am currently building a projct which uses the analoge input from a 3 axis accelerometer and turns this into a proportional servo output.

I have now managed to get y chip to read ADC...

Thanks yet again mister_e! You should move in with me, that way i wouldnt have to use the net to bother yo every other day :p

and yes i put the dec2 myvar on the lcdout command so all works now :)...

;) Cheers, so any clues as to whats wrong now? i dont get any reaction on the LCD and i get several ports flash high then low
