Thanks PCM, you were right in all your points.

I could not find again the post by Ttelmah, but this is his routine:

void myint(void) {
new=input_b();
value=new^old; ...

Hi, I have a doubt about the interrupts.

My question is:

I have a done a program that reads an encoder by the portbB, actually, I changed the program that Ttelmah left, then I put a timer and I ...

i am right now doing something with a position feedback but its not working elegant. : (((

this has worked for me:

#include <18F4550.h>
#use delay (clock=20000000)
#fuses HS,NOWDT,NOPROTECT,NOLVP

#define red PIN_B5
#define green PIN_A5

signed int16 value = -2;
s ...

upload a TXT file or an Excel file with all the data you want to fit and i will do it for you.

but, I can't have it for today ... I am also in troubles with some software hahahaha : )

what is it value?, what are you trying to do?

#hazardmike,

I could move the motor with a duty cycle of 5.25%, its the slowest i can get ...

how is your work?

and did you try to use a LM35 temperature sensor?, or Is not enough for your project?

its linear.

by the way, with ...

I solved.

the problem is that first i have to include stdlib.h instead of usb_cdc:

#include <stdlib.h>
#include ".\include\usb_cdc.h"

I didnt know that, I am new in CCS, ...

Hi,

I have this little program to test how to write strings using USB, I used to use a similar one in RS232, but now, i am trying to change everything for USB.

Ok, my problem is when I compile ...

first that all, you should do a kind of simulation, Excel can help you a lot.

Make a graph of the equation, test if all your point are in the curve, or at least close (your know which is your bette ...

I got this equation:

Return = 0.0008value**2 - 0.1224value - 42.736

Its not actually correct but fits the point you gave us in the original post, now its up to you do it better ; )

PCM already did your work ; )))

but really, try fitting a equation, even you can do it with excel : )

ok, I did it very faster and i believe is an exponential function, of course, with the Spline you will find a polynomial, and insted of all those "else if" you put the function : )))))))))))

you can convert all those points in a polynomial function.

I use to use Cubic Spline, that means that you will find a function and it will cross each one of the point of your table, and of course, ...
