multi function button handling

Screaming_Rabbit · December 6, 2006, 11:45pm

Hello

Does anybody know about it’s possible to implement following multi function button handling by programming?

Description:

I’d like to have 4 or more “shift” buttons (Shift 1-4) to select the functions for Buttons A+B.

Example:

I press and hold [shift1] the functions the MidiBox sends now would be “CUT” for [buttonA] and “PASTE” for [buttonB]
I press and hold [shift2] the functions the MidiBox sends now would be “JUMP to Clip Left” for [buttonA] and “JUMP to Clip Right” for [buttonB]
I press and hold [shift3] the functions the MidiBox sends now would be “JUMP to Marker Left” for [buttonA] and “JUMP to Marker Right” for [buttonB]

… and so on

Logical Shematic:

Button B ___/ _____________________________________________

| | | |

Button A ___/ _______|____________|____________|________ |

| | | | | | | |

Shift1/–/ 2/–/ 3/–/ 4/–/

| | | | | | | |

/ / / / / / / /

===========================================

| F F F F F F F F |

| u u u u u u u u |

| n n n n n n n n |

| k k k k k k k k |

| t t t t t t t t |

| i i i i i i i i |

| o o o o o o o o |

| n n n n n n n n |

| |

| 1 1 2 2 3 3 4 4 |

| A B A B A B A B |

==========================================

Thanks and Greets

Are you doing this in assembly or C?

I do something like this in my project. It looks something like this.

From DIN_NotifyToggle() I have ButtonHandler(pin)

/* global var */
shiftmode = 0;

/* you simply toggle a shift mode to an ON state.
 * If you want to hold down a shift, then simply check the pin to see if its currently closed.
 *
*/


void ButtonHandler(unsigned char pin) {

	switch(pin) 
	{
		case DIN_A_Button:

		switch(shiftmode) {

			case MODE1:
				DoCut();
				break;

			case MODE2:
				DoJumpLeft();				
				break;

			case MODE3:
				DoJumpMarkerLeft();				
				break;								
			<etc...>		
		}					
			break;

		case DIN_B_Button:

		switch(shiftmode ) {

			case MODE1:
				DoPaste();
				break;

			case MODE2:
				DoJumpRight();				
				break;

			case MODE3:
				DoJumpMarkerRight();				
				break;				

			<etc...>

		}

			break;

		case DIN_Shift1:
			shiftmode = MODE1;
		break;

		case DIN_Shift2:
			shiftmode = MODE2;
		break;

		case DIN_Shift3:
			shiftmode = MODE3;
		break;

		case DIN_Shift4:
			shiftmode = MODE4;
		break;


	}

I prefer “C”

THX for the code-example, Jack!
