Treadmill Controller - v3
Version 3 of this App continues to provide the ability to control compatible treadmills with audio "chirps". It adds the power to create workouts for those treadmills controlled by Secure Digital Cards.

Warnings
- Consult your physician before doing any exercise, including that configured or created by this program.
- I'm a programmer not a doctor or trainer. I am not qualified to provide safe exercises. I've never met you and have never seen your equipment. Use this program at your own risk. If you hurt yourself or your equipment it is not my fault.
- For Chirp Control, the iPhone volume must be loud enough for the treadmill to hear the instructions being given by the "chirps". On the other hand, very loud "chirps" may damage the audio input circuitry of the treadmill. Set the "chirp" volume to a comfortable level. Adjust the volume up and down until the treadmill flawlessly executes a workout. There is a rare chance some treadmill models simply misunderstand commands on occasion and there is nothing you can do about it.
- Chirp commands for an incline or speed not available on your treadmill may cause the entire command to be ignored. It will be as if no command was sent. Make sure your treadmill can do what you ask as you create your workouts.

Program Operation
When the program starts you see a splash screen with an info-button that tells you about the application and four menu-buttons: "Manage Your Workouts", "Create/Modify A Workout", "Chirp A Library Workout" and "Export A Library Workout".

Manage Your Workouts
This button allows you to delete your previously defined user workouts.

Create/Modify A Workout
This button takes you to a list of existing workouts. Select one to use as a starting point for your new workout.
- A treadmill workout is composed of segments. Each segment specifies a Duration, Speed, and Incline.
- The lower region of the workout creation screen has three pickers: Duration, Speed, and Incline
- You add a new segment to the workout by tapping the Insertion Control (the green +) at the top left of the pickers. The new segment is inserted below the selected table row
- You delete a segment by tapping the Deletion Control (the red -) at the top right of the pickers.
- Insertion and deletion work the same way in the graphing modes
- At the top of the workout creation screen is a Tool Bar with 5 buttons. Cancel abandons changes and exits the screen. Save saves this workout to a file. The remaining 3 buttons cycle between the table listing and 3 graphs.

Chirp A Library Workout
This button lists your available workouts. Choosing one starts running the workout and generating "chirps". Enable control by connecting an audio cable from the iPhone/iPad/iTouch earphone jack to the treadmill "chirp" input. Many treadmills also have a special setting to enable "chirp" control. See your treadmill manual to confirm the correct configuration.
- Graphs for speed, incline, and distance are displayed in red when a workout is selected for playing.
- Segments change from red to green as they are "played".
- A command to stop the treadmill is sent when a workout completes. However (***CAUTION***) no such command is sent if you stop the program or navigate out of the "Now Playing" view. The treadmill will continue indefinitely at the last speed and incline.

Export A Library Workout
This button also lists your available workouts. Choosing one, however, does not start "playing" the workout. Instead it generates a file and offers to email it to you. Open the email on a computer that has a SD Card writer and, following the instructions in the email, write the attached file onto a suitable SD Card. Plug the SD Card into your treadmill and enjoy your custom workout.

Note: This program creates a valid workout file but you may have to experiment. Many treadmills do not work with SD Cards greater than 2 GB. Some treadmills are very picky and only work with certain brands/models of SD Card.
