I'm posting this in hope that someone who has actually registered on this site will post something. there are so many people viewing this, but not posting anything. with that said, I thought this would be a nice place for people to discuss encoders. of course, my main motivation is that these things have been my killing me over the past month. I have tried numerous things, and I can never seem to get it to work. Coding, for the most part, I don't think is a problem. I'm using 2004's code written by Mr. Watson that supports encoders and interrupts. I have everything configured, the only thing that could possible be keeping the encoder from working is my code in User_Routines_Fast.c
what the code does is this, when the third joystick is pushed forward, the arm on last year's robot goes up untill the encoder has "clicked" 12 times. then the motor on the arm is set to neutral. it's as simple as that. (for testing purposes).
Code:
static long lec = 0; //lec = encoder count
lec = lec + Get_Left_Encoder_Count(); //add previous count
//plus the new count
//the static long is supposed to hold the value every loop
if (lec >= 12)
{
pwm02 = 127; //set it to neutral
}
else
{
pwm02 = p3_y;
}
can you please tell me why this won't work, or if you think it should. please tell me yourself and don't refer me to somewhere. I've spent so much time, and a simple few lines of code would help me to understand this almost completely. (don't forget, Mr. Watson's 2004 encoder code is what I'm using.)
HELP!!!
thanks,
Stephen
