In Program 28-6, the code has been modified so that the gain and the direction of motion are a function of the potentiometer reading. It is integral to the program there is no gain-controlling cog. The constants PotMin and PotMax have also been added to the code but are set to minimum (0) and maximum (100) values. As you play with the program, set these to various values to see how the program responds to the changes you make. Watch the potentiometer position on the LCD. Make it go to 0, the mid position to stop the motor. Next, we need a program that moves the motor back and forth a few counts at a time automatically. This will allow us to play with the gain in the system in real time without having to worry about actually running the motor back and forth. In this program we add a known, fixed count (read from a potentiometer) to the target position and then move to that position. We must add code (the StrtFlag method) to allow the program to wait until each move is completed. The system is not aware of the motor motion and therefore does not do this automatically. Then we pause for a short time, subtract the same count from the target position, and move back to where we started from. We then pause again and repeat the program. The code that does just that is provided in Program 28-7. Note that the only change between the positive and the negative moves is the addition or subtraction from the target position. It is important to understand that we are always trying to get to the target position. In later programs we will create time-dependent target position profiles to create the move profiles we need.
