Add push button tp Micro-controller

Question

Hi All,
I appreciate if you read my problem and answer me:).
I am using CSMB12 micro controller, which has port S as a SCI. 2 pins of this port is TXT and 2 pins are RXT. Right now i used one pair of these pins for both Bluetooth and LCD. now I need to add push button to my system, whenever I click on the push button, my micro start working and calculating the program, and whenever i click it again, it stops calculating and show the value on the LCD, and use another button for sending data by Bluetooth.
my problem is:
1-I used one SCI for both LCD and Bluetooth, how can I separate them?
2-Do you have a y sample codes for adding push button switch?
If you need my code, i can upload it.
really thank you.
Regards,
Sb

Just create the the UINavigationController wherever you need to show its root view controller. With no storyboard segue you would typically use something like this. I initiated from a UIButton action for this example. Instead of a generic UITableViewController, use the custom view controller class of your root view controller (PauseMenuTableViewController?). If you are using old-school nib/xib, replace initWithStyle with initWithNibName.
- (IBAction)showWhateverViewButtonClick:(id)sender {
    // create whatever view controller type will be the root of the navigation controller
    UIViewController *rootViewController = [[UITableViewController alloc] initWithStyle:UITableViewStylePlain];
    // create a navigation controller using that view controller for the root
    UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:rootViewController];
    // show the navigation controller (modal)
    [self presentViewController:navigationController animated:YES completion:NULL];
