Hi

Is there a signed flavour of uint8_t?

This should be "int8_t".

Quote
Also, what is the purpose of calling "m2.checkKey();" multiple times within the main loop?

A call to "checkKey()" polls the values of the rotary encoder and the other keys. There is no interrupt based check of the rotary encoder, instead M2tklib requires as much calls to "checkKey()" as possible.

I'm also confused about how i pass a value back through the callback procedure. I was looking at the example code and i'm unsure how i would use that. Say for example i wanted to do a Serial.print(); of the current S8NUM value for el_u1.

You need to use global variables to pass values to a callback procedure (as you did correctly in the second code example).

This will do the print for each changed value:
Code: [Select]
uint8_t global_value = 0;

uint8_t u8_cb(m2_rom_void_p element, uint8_t msg, uint8_t val)
{
  if ( msg == M2_U8_MSG_SET_VALUE )
  {
    global_value = val;
    Serial.print(global_value);
  }
  return global_value;
}

Hi,

For a project I use an old loran C navigator box with intergrated keypad. It has 20 keys in a 5x8 matrix, yes very inefficient.

How should I modify the library to be able to use a matrix keypad?
So if I look deeper into the code I should change m2_arduino_get_key in m2esarduino.c to return the messages on result of a keypress on my matrix keypad. Is that the only place where I should change the code?
Would it be possible to make extra messages for the numbers 0...9?

Cheers,

Marijn

Hi

1) Extend the event source to generate the new events (M2_EP_MSG_KEY_1, M2_EP_MSG_KEY_2, ...)

2)  Introduce a new (corresponding) element msg, e.g. M2_EL_MSG_KEY_1
Extend one of the event handlers to process the new key event, for example extend
Code: [Select]
uint8_t m2_eh_4bs(m2_p ep, uint8_t msg, uint8_t arg1, uint8_t arg2)

Then add this code to the event handler (for each event):

Code: [Select]
  case M2_EP_MSG_KEY_1:
    m2_nav_prepare_fn_arg_parent_element(nav);
    m2_fn_arg_call(M2_EL_MSG_KEY_1); // assign the char
    return m2_nav_user_next(nav); // go to next position
   

3) Next step is to make the elements aware about the new element messages.
For example M2_TEXT would make sense here (m2eltext.c):

Extend the char processing function: M2_EL_FN_DEF(m2_el_char_fn)

Code: [Select]
  case M2_EL_MSG_KEY_1:
      cp = m2_get_char_ptr(fn_arg->nav);
      *cp = '1';
      return 1;


Of course: not tested...

Thanks Oliver,

I will try to extend the lib that way.
The matrix keypad question was a RTFM problem   :smiley-red:
I used m2.SetKey to store the result of the matrix into the que.
I'm still amazed about this lib...
Cheers,

Jelbert

Yes, it should be possible to use setKey() if you do not want to rewrite the event source.

Hi Jelbert

I have added the mentioned code for the keypad support. See http://code.google.com/p/m2tklib/issues/detail?id=108.
Instead of extending the existing handlers, i have introduced m2_eh_4bks and m2_eh_6bks (and extended m2_eh_4bsts and m2_eh_6bsts) to support the keypad values.

Just for reference, the new code in the event handler was wrong. Correct code is:
Code: [Select]

  case M2_EP_MSG_KEY_1:
    m2_nav_prepare_fn_arg_current_element(nav);
    m2_fn_arg_call(M2_EL_MSG_KEY_1); // assign the char
    return m2_nav_user_next(nav); // go to next position


I have introduced the following constants (which can be used with setKey or as return value of the event source):
#define M2_KEY_HASH 35
#define M2_KEY_STAR 42
#define M2_KEY_0 48
#define M2_KEY_1 49
#define M2_KEY_2 50
#define M2_KEY_3 51
#define M2_KEY_4 52
#define M2_KEY_5 53
#define M2_KEY_6 54
#define M2_KEY_7 55
#define M2_KEY_8 56
#define M2_KEY_9 57

Additionally you can use any other ASCII code like 'a', 'b', 'c', etc.., so m2.setKey('B') will send the ASCII B to the element. At the moment only M2_TEXT will be able to handle these new codes.

Let me know your variant of m2tklib, then i will upload a prerelease of m2tklib including keypad support.

Hi Oliver and others,

Based on the 2L example I went on with my  code. And made some modifications in oa the used font to create a space on the top of the display for a status line.
At frst I had troubles with the display suddenly blanking but the arduino kept on running.
That was fixed with a buffer that was too long in the drawStatus routine and moving the fontsetting to setup.
After that everything ran fine for a long while.

But now, when just waiting in the main menu, the display blanks again after 8 hours or so.
Is there a way to reset the display system (software part), without resetting the arduino?

Besides the drawstatus routine I included most of the rest for completeness sake.

here is the drawStatus routine
Code: [Select]
    void drawStatus(void)
{

  static long bmpTime=0;
  static char StatBuf[26];
  static float temprature;
  static float pressure;
  static int hi, lo;

     hi=int(RATemp.getAverage());
    lo=(RATemp.getAverage()-float(hi))*100;

  String line =  String(rtc.getTimeStr());// + bmp.readPressure() + " " + bmp.readTemperature()+" C");
  line += " ";
  line +=  (int(RADruk.getAverage())); //
  if(statMsgStat==1 && m2.getRoot() == &m2_null_element)
  {
    switch (Step)
    {
    case 1:
      line += " 12u  ";
      break;
    case 2:
      line += " 1d   ";
      break;
    case 3:
      line += " 1.5d ";
      break;
    case 4:
      line += " 2d   ";
      break;
    case 5:
      line += " 2.5d ";
      break;
    case 6:
      line += " 3d   ";
      break;
    case 7:
      line += " 3.5d ";
      break;
    case 8:
      line += " 4d   ";
      break;
    default:
      line += "      ";
      break;     
    }
  }
  else
    line += "      ";
  line.concat(hi);
  line += '.';
  line.concat(lo);
  if(lo<10)
    line +='0';
  line += "C";
  line.toCharArray(StatBuf,26);
  u8g.drawStr(0,7, StatBuf);

}

There is the procedure "begin" (http://code.google.com/p/u8glib/wiki/userreference#begin) which does a reset of the display for newer versions of U8glib.

Today, I have released version 1.11 of M2tklib.

M2tklib is a menu/GUI library for graphics and character displays.
Projekt page: http://code.google.com/p/m2tklib/

The new version is available for download:
  @Google: http://code.google.com/p/m2tklib/downloads/list
  @Bintray: https://bintray.com/olikraus/M2tklib

From the ChangeLog:
   * Keypad Support for M2_TEXT and M2_U32NUM (Issue 108)
   * Fixed XBM code (Issues 110, 111)
   * Touch screen support for M2_STRLIST and M2_VSB (Issue 112)
   * New color graphics handler for U8glib (Issue 113)
   * Quick and Home keys (Issues 114 and 115)
   * Changed default behavioir for M2_ALGIN (Issue 121)
   * New element: M2_COMBOFN (Issue 122)
   * New tutorial on event sources (Issues  117 and 123)

Hi Oliver,
I like your work quite a lot, but I feel kinda lost now.
Is it possible to declare conditional elements and what is the best approach you'd recommend?
I'd like to create some menu entries, which are dependent on other settings entered in other menu points (global variables).
Menu A (something)
Menu B (something to change a global variable)
Menu C (only visible, if variable in Menu B == 1)
Menu D (only visible, if variable in Menu C == 1)
Menu E (something else)

I guess I should start around STRLIST, but I was wondering if there's a better solution.
Your insight is much appreciated.

olikraus

Hi

STRLIST is one option, but might be limited. Another option is to create several dialog boxes, which only differe in the visibility of some elements. Then use M2_BUTTON with conditoinal setRoot command in the callback action to jump to the one dialog, which has the intended visible elements. Note, that you can reuse elements (or complete element trees) in more than one dialog.
Then, finally, there is M2_HIDE(). I still did not document M2_HIDE, but i think there should be an example (HideS8Num).

https://code.google.com/p/m2tklib/source/browse/arduino/u8g/HideS8Num/HideS8Num.pde

Oliver

Oliver, thank you so much for your prompt reply, it was most helpful!
M2_HIDE() seems to be perfect, it is the way to go. Wish I had found it sooner. :)
Are there any other notable undocumented functions?

olikraus

I think M2_HIDE is the only undocumented element.

Oliver

M2_HIDE does what it says and only that, it hides an element, but it cannot remove the space it leaves behind and it does not work with U32NUMFN, so one needs to hide a V/H/GRIDLIST in that case.
STRLIST turned out to be the least hassle-free solution to hide some top level menu elements, if you need VSB.
Different strings are shown according to the state of some variables and lower menu entries are assigned with setRoot in the callback procedure.
I think creating different dialog boxes would have been way too over-complicated with Menu(X)2L.
Is there any way to adjust the vertical spacing in-between strings of STRLIST?

Mit freundlichen Grüßen

olikraus

I reviewed my own code.

M2_HIDE(element_name, fmt, &ctl_var, &child_name);

I think if ctl_var is 2 or higher, then the size will be reduced to zero.
So actually ctl_var can have three values:
0: child is visible
1: child is not visible, but space will be occupied
2: child is not visible and also no space is reserved for the child

The vertical spacing within STRLIST depends on the font only.
