Ok, thanks. I will fix this in the next release.
As a workaround, you can remove or comment out line 80:
Code:
// UCSR0B = 0;

Hi
What is the u8glib version? What are the exact compiler errors?

Thanks, Oliver

instead of
Code:
itoa(val, string, 10);
use
Code:
string[0] = val;
string[1] = '\0';

I did some work with the EA DOGXL160, which is a 160x104 GLCD (http://www.lcd-module.com/products/dog.html).  The display is very large and has a good visibility also from 1m (or more) distance.

It is supported by u8glib for Arduino: http://code.google.com/p/u8glib/wiki/device.
U8glib comes with a lot of fonts (>200). I guess for your application, some really big fonts are required. Largest font for u8glib has 49 pixel height, so it is nearly half of the display height. Font list is here: http://code.google.com/p/u8glib/wiki/fontsize.

U8glib is also supported by the open source GUI library m2tklib (http://code.google.com/p/m2tklib/).

A schematic for the DOGXL160 is here: http://code.google.com/p/dogm128/wiki/dogxl160

Note: Frame rate is an issue for all big displays. With u8glib it is somewhere between 3 and 10 FPS with the SPI interface.

Hi

The submitter  of this topic
http://arduino.cc/forum/index.php/topic,50524.0.html
has once created the dogs102 shield.

The old library dogm128 and the new u8glib are fully compatible to this shield.

532  Using Arduino / Storage / Re: SdFat: How to go to parent directory? on: April 23, 2012, 11:30:17 pm
Hi

Thanks a lot for the quick reply. I made openParent a public member, but the following code does not work:

Code:
      if ( !sd.vwd()->isRoot() )
        sd.vwd()->openParent(sd.vwd());

Maybe I used this procedure in a wrong way. What would be a proper way to call "openParent"?

I am working on a file selection box (LCD), where the user should be able to navigate through the folder hierachy. For this purpose my idea was to modify "vwd".

Thanks, Oliver
533  Using Arduino / Storage / SdFat: How to go to parent directory? on: April 23, 2012, 04:40:35 pm
I wonder how to go to the parent directory with SdFat.

SdFat sd;
sd.vwd()->chdir("..") does nothing
sd.vwd()->chdir() goes to the root directory

Any hints?

Thanks, Oliver

What about a graphics display? As much custom graphics as you want.
You could select one or more fonts from here http://code.google.com/p/u8glib/wiki/fontsize.
Ensure that the display is supported: http://code.google.com/p/u8glib/wiki/device.

For example ST7920 based displays are 5V tolerant and can be used directly with the Arduino.
Additionally the following NHD display can be used in parallel or serial mode:
http://www.newhavendisplay.com/index.php?main_page=index&cPath=21_103
Using the 4x6 font, you will have 6 lines with 48 chars per line.
With the 6x10 font there are 4 lines with 32 chars per line.

oh, i understand. I am not an expert on println, but maybe "println((char)val)" helps.

U8g has such an example:
http://code.google.com/p/u8glib/source/browse/sys/arduino/Console/Console.pde

I think u8g will also support your PCD8544 based display. Please check http://code.google.com/p/u8glib/wiki/device.

You probably should do some deeper investigation. The "40 pin" applies to the module connector, not to the display connector. And with a closer look to the module connector, you will see that there are three unused pins:



So both displays have 37 active pins.

Hi liudr

Good posting. You could remove "character" from the topic. It applies to graphic LCDs also.
In fact, it also applies to OLEDs.

Where is the sticky button?  smiley-wink

Could be similar to this display:

Also a good question. For sure, u8glib does not support any digraphs.
