controlP5 (for GUI)
serial (to communicate with a device on COM port)

... the device is a GSM SIM900 module that can understand AT commands. when I create a session in PUTTY for COM port, for every AT command I type and press ENTER, I get an acknowledgement. For e.g.

AT
OK

where AT was the command I typed and OK was the acknowledgement I got.

In p3, I made a GUI that contains 2 textboxes and a button.

I also created a serial handle,

mpo = new Serial(this,Serial.list()[0],9600);

mpo is global object of class Serial

On clicking the button, the content in the textboxes is processed and if a condition is met, then some functions in serial module are called.

mpo.clear();  
mpo.write("AT\n");

... I also have this function,

void serialEvent(Serial mp){  
ins = mp.readString();  
print(ins);  
}  

where ins is a global String object. This function, I suppose, is called whenever I send commands to module and not when the module acknowledges. So, it prints AT, but doesn't print OK... Is there any way this problem can be solved?

I'm trying to make a super simple drum sequencer using controlp5 and the minim library's.

At the moment i'm just trying to combine the examples, of cp5's matrix and minims trigger sample, with my own drum samples. I'm super knew to this and was wondering if someone could walk me through this step?

after this I think I could probably get my head round and some sliders for volume and and stuff.

Thanks :)

I made a complex IU where tabs may cover some controller. I want the priority to be given to the table button. But even if the tab is drawn above, i click on the button in the background.

I tried a function like myTab.onEnter(toFront);

With the callback listener toFront is simply

CallbackListener toFront = new CallbackListener() {
      public void controlEvent(CallbackEvent theEvent) {
        theEvent.getController().bringToFront();
      }
    };

but this option works only with controller object...

Any tips ?

All buttons are built using controlP5. I have used SMT library for multi-touch. I have defined zone for each button and defined touchUp and touchDown methods (SMT methods) for each button, to detect click on each button.

The problem is I cannot enable two button at the same time. (I think SMT is not calling two different touchDown method for different buttons, but not sure)

Please suggest if there is any solution. It will be very helpful if I get the any solution as soon as possible. Thank you in advance.
