I don't think connecting the LCD to the main hardware serial port is a good idea.
I read though the last e-mails. For sure it seems to be strange, that the day number is 45, but what should be checked?
Oliver
Ok Oliver, thanks for the information,
then I can use each pins that I want for lcd ?
Changing pin for lcd it's working ...
warm regards
gnux
Hi Oliver,
changing the pin 0 and 1 the menu it's working ok now (i will consider this for the future ) ...
Very helpfull
Good to read that you had some success
Oliver
Thanks again :-), I'll let you know about the next steps
Ciao Oliver how are you,
so now that I've take more confidence with your menu I'd like to do a menu that when I turn on arduino put into display :
colums :
0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19
1°row| Arduino Welcome
2°row| Ver . 1.0
3°row| 06 - 02 - 2013
4°row| 10 : 23 : 55
and then just when I press the first time select button appears the other menu, then will be exit to all menu will return to this screen,
is possible from your point of view ? could you give me suggest ?
thanks for the support,
have nice day,
gnux
Sure, this is described in tutorial 6: Google Code Archive - Long-term storage for Google Code Project Hosting.
- You start with an empty element: apply &m2_null_element as first element to M2tk. This will disable all menues.
- draw your personal intro screen (as described above), by using the normal LiquidCrystal commands.
- In the main "loop()" do the following:
if ( m2.getRoot() == &m2_null_element ) {
if ( m2.getKey() != M2_KEY_NONE )
m2.setRoot(&el_my_own_top_menu);
}
This will activate your menu once the user has pressed a key.
- A soon as the user has finished working with your menu, use
m2.setRoot(&m2_null_element);
to disable your menu again. Of course you need to redraw your own screen again.
More details are given in tutorial 6

Ciao Oliver,
thanks for the information,
I try and however I'll let you know and for example if i would like put in display time is better to use "normal LiquidCrystal commands" also ? and when i re-draw my screen again I call procedure after m2.setRoot(&m2_null_element); ? Is there a simply example that I can use for take confidence ?
so how do you will implement it ?
thanks 10000000 again :-),
gnnux
Is there a simply example that I can use for take confidence ?
Unfortunately i did not made an example for LiquidCrystal, but you can take over the GLCD tutorial 1:1.
In the "loop()" procedure, check for the &m2_null_element as root element and if this is true, than redraw your time screen
I hope all is written in tutorial 6
Oliver
Ciao Oliver,
I've just tried to do this simple try with a simple combo example ... below the code:
#include <LiquidCrystal.h>
#include "M2tk.h"
#include "utility/m2ghlc.h"
LiquidCrystal lcd(10, 9, 3, 2, 1, 0);
uint8_t uiKeySelectPin = 22;
uint8_t uiKeyNextPin = 26;
uint8_t select_color = 0;
uint8_t select_priority = 0;
void fn_ok(m2_el_fnarg_p fnarg) {
/* accept selection */
}
void fn_cancel(m2_el_fnarg_p fnarg) {
/* discard selection */
}
const char *fn_idx_to_color(uint8_t idx)
{
if ( idx == 0 )
return "red";
else if (idx == 1 )
return "green";
return "blue";
}
const char *fn_idx_to_priority(uint8_t idx)
{
switch(idx)
{
case 0: return "lowest";
case 1: return "low";
case 2: return "medium";
case 3: return "high";
case 4: return "highest";
}
return "";
}
M2_LABEL(el_label1, NULL, "Color:");
M2_COMBO(el_combo1, NULL, &select_color, 3, fn_idx_to_color);
M2_LABEL(el_label2, NULL, "Prio.: ");
M2_COMBO(el_combo2, "v1", &select_priority, 5, fn_idx_to_priority);
M2_BUTTON(el_cancel, NULL, "cancel", fn_cancel);
M2_BUTTON(el_ok, NULL, " ok ", fn_ok);
M2_LIST(list) = {
&el_label1, &el_combo1,
&el_label2, &el_combo2,
&el_cancel, &el_ok
};
M2_GRIDLIST(list_element, "c2",list);
M2tk m2(&list_element, m2_es_arduino, m2_eh_2bs, m2_gh_lc);
void setup() {
m2_SetLiquidCrystal(&lcd, 20, 4);
m2.setPin(M2_KEY_SELECT, uiKeySelectPin);
m2.setPin(M2_KEY_NEXT, uiKeyNextPin);
}
void loop() {
if ( m2.getRoot() == &m2_null_element ) {
if ( m2.getKey() != M2_KEY_NONE )
m2.setRoot(&list_element);
}
}
When I push button nothing appears I've tried from serial menu also but nothing appears... so now I've a trouble ...
into the condition
m2.getRoot() == &m2_null_element
is necessary to assign "&m2_null_element" into the setup ? if yes is there particular sintax to follow ?
because looking the sketch there is no assignment for and then the condition will be never verified right ?
thanks
gnux
Hi
Instead of
M2tk m2(&list_element, m2_es_arduino, m2_eh_2bs, m2_gh_lc);
use
M2tk m2(&m2_null_element m2_es_arduino, m2_eh_2bs, m2_gh_lc);
to assign the null element at the beginning.
And then, the loop procedure MUST be expanded to this (see also the mentioned tutorial!!!)
void loop(void) {
if ( m2.getRoot() == &m2_null_element ) {
if ( m2.getKey() != M2_KEY_NONE )
m2.setRoot(&list_element);
}
m2.checkKey();
if ( m2.handleKey() ) {
m2.draw();
}
}
You must not forget to call checkKey(),
Oliver
Thanks Oliver for your precious assistance ...
this was a terrible night ... so I was wake up at 3:45 in the morning ... then I m put in front the computer for try to work ... I will go home i will try ...
Thanks 10000
Gnux
Ciao Oliver,
I've did a couple of try ...
so i don't understand why I've like into tutorial explain I've put :
M2_ROOT(el_switch_to_graphics, NULL, "Show Graphics", &m2_null_element);
and I've tried also:
if ( m2.getRoot() == &m2_null_element ) {
if ( m2.getKey() != M2_KEY_NONE )
m2.setRoot(&list_element);
}
m2.checkKey();
if ( m2.handleKey() ) {
m2.draw();
}
like your suggestion seems that the condition is always verified because I've put serial debug print for see where the program pass and pass to here when I press the button:
if ( m2.getKey() != M2_KEY_NONE )
m2.setRoot(&list_element);
... if put == 0 ...to here :
m2.getRoot() == &m2_null_element
the menu has been disappeared but when i check press the button the menu doesn't appers ... where could be the issues ? i very appreciate your support
thanks
gnux
hmm... i have some difficulties to understand your question. But maybe i should clarify the code a little bit with some comments:
// check for manual written screen
if ( m2.getRoot() == &m2_null_element )
{
// yes, it is our manual written screen
// place your manual commands here
lcd.print("...");
...
// check if the user has pressed a key while manual screen is active
if ( m2.getKey() != M2_KEY_NONE )
m2.setRoot(&list_element); // refer to a suitable menu
}
// do normal menu display
m2.checkKey();
if ( m2.handleKey() ) {
m2.draw();
}
maybe you can repeat your question including a more complete code example...
Oliver
Good Morning Oliver, sorry if i didn't answer to you yestarday evening but I was completed boiled ... :*
So for example this below reported is a simple Combo Example Simple Sketch where Im trying to:
- at the start show nothing
- then when I press key show my combo menu
So from Theoretically stand point I've understand and I'm ok what you mean at least :-), but trying to use the code below reported is not working ... So with the normal example everything is working, display, button are ok ... So maybe I did a error in some other part but I don't where to be honest because is a simple example and I've just change the condition and null element and put the condition ...
#include <LiquidCrystal.h>
#include "M2tk.h"
#include "utility/m2ghlc.h"
LiquidCrystal lcd(10, 9, 3, 2, 1, 0);
uint8_t uiKeySelectPin = 22;
uint8_t uiKeyNextPin = 26;
uint8_t select_color = 0;
uint8_t select_priority = 0;
void fn_ok(m2_el_fnarg_p fnarg) {
/* accept selection */
}
void fn_cancel(m2_el_fnarg_p fnarg) {
/* discard selection */
}
const char *fn_idx_to_color(uint8_t idx)
{
if ( idx == 0 )
return "red";
else if (idx == 1 )
return "green";
return "blue";
}
const char *fn_idx_to_priority(uint8_t idx)
{
switch(idx)
{
case 0: return "lowest";
case 1: return "low";
case 2: return "medium";
case 3: return "high";
case 4: return "highest";
}
return "";
}
M2_LABEL(el_label1, NULL, "Color:");
M2_COMBO(el_combo1, NULL, &select_color, 3, fn_idx_to_color);
M2_LABEL(el_label2, NULL, "Prio.: ");
M2_COMBO(el_combo2, "v1", &select_priority, 5, fn_idx_to_priority);
M2_BUTTON(el_cancel, NULL, "cancel", fn_cancel);
M2_BUTTON(el_ok, NULL, " ok ", fn_ok);
M2_LIST(list) = {
&el_label1, &el_combo1,
&el_label2, &el_combo2,
&el_cancel, &el_ok
};
M2_GRIDLIST(list_element, "c2",list);
M2tk m2(&m2_null_element, m2_es_arduino, m2_eh_2bs, m2_gh_lc);
M2_ROOT(el_switch_to_graphics, NULL, "Show Graphics", &m2_null_element);
void setup() {
// Serial.begin(9600);
m2_SetLiquidCrystal(&lcd, 20, 4);
m2.setPin(M2_KEY_SELECT, uiKeySelectPin);
m2.setPin(M2_KEY_NEXT, uiKeyNextPin);
}
void loop(void) {
if ( m2.getRoot() == &m2_null_element )
{
// yes, it is our manual written screen
// place your manual commands here
lcd.print("...");
// check if the user has pressed a key while manual screen is active
if ( m2.getKey() != M2_KEY_NONE )
m2.setRoot(&list_element); // refer to a suitable menu
}
// do normal menu display
m2.checkKey();
if ( m2.handleKey() ) {
m2.draw();
}
}
So what I've note is this :
putting a simple like "debug print" for example:
void loop(void) {
if ( m2.getRoot() == &m2_null_element )
{
// yes, it is our manual written screen
// place your manual commands here
lcd.setCursor(0, 0);
lcd.print("Condition");
delay(1000);
// // check if the user has pressed a key while manual screen is active
if ( m2.getKey() != M2_KEY_NONE ) {
lcd.setCursor(0, 4);
lcd.print("Verificata");
lcd.setCursor(0, 4);
lcd.print(" ");
m2.setRoot(&list_element); // refer to a suitable menu
}
lcd.setCursor(0, 0);
lcd.print(" ");
delay(1000);
m2.checkKey();
}
}
The Condition is verified this ( m2.getRoot() == &m2_null_element ) one times ...then if enable also the second part
m2.checkKey();
if ( m2.handleKey() ) {
m2.draw();
}
execute at one times the first one part and then the if ( m2.handleKey() is verified to but for sure i didn't press but ... also because when appear a menu is stopped on the right element ...
Thanks
Gnux
wow and congratulation, you found a bug in M2tklib.
Thanks for that.
As a workaround, please extend the setup procedure to this:
void setup() {
// Serial.begin(9600);
m2_SetLiquidCrystal(&lcd, 20, 4);
m2.setPin(M2_KEY_SELECT, uiKeySelectPin);
m2.setPin(M2_KEY_NEXT, uiKeyNextPin);
m2.getKey(); // this is new, (bugfix workaround)
}
I will create an issue for this.
Thanks, Oliver
thanks to you Oliver, i ll try and i'll let you know
have nice week end
gnux
Ciao Oliver,
now it's working ...
Thanks 10000
