Hm, yeah, that's what I was afraid of...
Ok, here's my problem:
I need some way to do timed output, i.e. output voltage for a certain amount of time only. I'm writing a program for a steering wheel. So when you move the joystick right, it turns right. When you move the joystick left, it turns left. I kind of have it working, but the problem I'm having is that I can't control HOW MUCH the motor (that turns the wheel) turns. I was thinking of using PWM and use its cycles argument to time it...but I guess that won't work. So, how would I be able to do this?
This is my current code - it is modified from the default program:
'Beginning stuff
p1_x_old VAR BYTE
PWM2 VAR BYTE
p1_x_old = p1_X
PWM2 = 127
Mainloop:
'SERIN, etc
'My code follows
IF ABS (p1_x_old - p1_x) < 2 THEN skip2
IF p1_x_old < p1_x THEN skip1
PWM2 = 200
p1_x_old = p1_x
GOTO skip3
skip1:
PWM2 = 60
p1_x_old = p1_x
GOTO skip3
skip2:
PWM2 = 127
skip3:
'limits, SEROUT, etc
GOTO Mainloop
I know I've got a bit of a logic error (i.e. it doesn't take into account how much the joystick moved), but I think I'll be able to solve that once I can get a timed output
Or would a joystick-dependent voltage be the answer here?
Thanks!!
