661  Using Arduino / Displays / Re: M2tklib LCD 2x16 Decimal in input on: June 08, 2013, 02:52:28 pm
Hi

The idea is to use U32NUM in this case:
Assume you want to edit a number with one digit after the decimal point: float x = 12.3
  • Multiply the float with 10: x = 123
  • Convert the float into a long value l = 123
  • Let the user edit the number with format option ".1" (one digit after the dot)
  • Convert the long back to a float x = (float)l = 123
  • Divide the float by 10: x = 12.3

The attached picture was created with
Code:
U32NUM(my_u32_element, "a1c4.1", &u32val);

Arduino Stammtisch in BB, da käme ich schon eher mal vorbei...

Hallo aus BB.

Ich freue mich von Aktivitäten zum Arduino im Raum Stuttgart und BB zu hören,
zum Zielpublikum des Kurses würde ich mich aber nicht mehr unbedingt zählen.

You must download "glcd-v3-20111205.zip"

Did you download glcd-v3 from here http://code.google.com/p/glcd-arduino/downloads/list?

But it seems to be a KS0108 based display.

Is any of the ICs labeled with T6963 or RA6963?
Are the pins of the connector labeled with something?
Your pics are not clear enough to identify any pin names.

Great, I will close this issue for now. Let me know if you find some additional issues.

Hi

The HT1632 has now been integrated into U8glib. I have added the new constructor to HelloWorld and GraphicsTest examples (other examples will be updated for the final v1.13 release)

Code:
U8GLIB_HT1632_24X16 u8g(3, 2, 4); // WR = 3, DATA = 2, CS = 4

You should be able to change the Arduino pin numbers to whatever is required.
I have attached a prerelease with the new constructor call. Please let me know if this constructor call works correctly.
The virtual screen feature  (combination of four screens to one huge screen) should also be possible now.

Thanks, Oliver

Regarding U8glib: You must enclose the draw commands into the "picture loop".
See here: http://code.google.com/p/u8glib/wiki/thelloworld

Example:
Code:
  // picture loop
  u8g.firstPage(); 
  do {
    //Print a message to the LCD.
    u8g.setFont(u8g_font_unifont);
    u8g.drawStr( 0, 22, "Hello!");
    u8g.setFont(u8g_font_unifont);
    u8g.drawStr( 0, 33, "coordinate GPS");
     ...
  } while( u8g.nextPage() );

You can also use the "print()" command to draw strings on the GLCD.

Hi

Can you display something on your Display? Are the examples from the U8glib working?

U8glib supports the print() procedure, so everting what can be printed with Serial.print() can be used 1:1 with U8glib.

Hi

I am working on this.
The device has already been updated:

Multiple Displays: Yes, you can have multiple u8g structs/objects. You can also combine these u8g structs/objects to a larger "virtual" area. See the wiki entry for "virtual screen": http://code.google.com/p/u8glib/wiki/virtualscreen

Great picture. Thanks!
I have updated the u8glib gallery page.

Some additional work will be required to completly integrate HT1632 support into u8glib...

Anything is fine, but I think a picture of your current 24x16 will be sufficient.

Thanks a lot.
