and so i figured out the problem (after 2 weeks of gutwrentching testing). It was the code!

it should've been while(TMR2IF=0); rather than ==

:(

this is SO strange.

Now it's not working?

Does anyone know? Desperately seeking an answer

(the problem is that the motor isn't running continuously)

Wrong.

Code:
while (TMR2IF == 0);


This means "test to see if TMR2IF is equal to zero", and sit in the while loop if it is. In other words, pause at that point until TMR2IF is NOT equal to zero.

Changing it by taking out one of the = now means "make TMR2IF equal to zero" then the while statement tests to see if its argument is true (1). It isn't, because you set it to 0, so it doesn't pause at all.
