PIN 37 in your picture hast to be connected with GND

PIN 37 is R/W you can't write when the PIN is HIGH. See the application 
examples which came with the display.

Feature Request: low power mode

I would like to see a power down function for when that disables all voltage 
boot and puts the display into a low power mode.

Conflicting return type error on compile with Arduino 0022

Upgrading to Arduino 0022 and latest dogLCD library I'm now receiving the 
following error when compiling my projects:


\Arduino\libraries\doglcd/DogLcd.h:236: error: conflicting return type 
specified for 'virtual size_t DogLcd::write(uint8_t)'

Request for importing library

Hello,

I would like to use your library with the Spark Core. 
It means I have to contribute your library on their website : 
https://www.spark.io/build

Do you agree for me to do it or do you want to do it yourself ?

Thanks

Alexandre

createChar method uses different datatype from corresponding method in LiquidCrystal.

What steps will reproduce the problem?
1. Use createChar function on object of DogLcd class.

What do you see instead?
compiler error

LiquidCrystal::createChar expects parameters of type uint8_t or byte;
DogLcd::createChar expects parameters of type int.

Easy to work around, but may want to change for consistency/compatibility.

Custom characters are not printed unless home() or setCursor() was called

What steps will reproduce the problem?
You define a custom character with `lcd.createChar()`
You try to print the newly created character on the display.
The character is *not* displayed.

You *have* to call either `lcd.home()` or `lcd.setCursor()` after the
definition of the char with `lcd.createChar()`

Reason for this error is unknown.
Workaround :
Define characters before you start printing anything on the display.

3.3v issue, very dim display

Hi

First many thanks for the great library!

I am using this with a dog081 lcd and arduino, all works fine when powering it 
with 5v but when i switch over to 3.3v (I have measured and assured my voltage 
reaching the screen) I get a very dim display. I initiate the display in the 3v 
vcc mode (according to the written wiki) and even set the contrast to max 
allowed but still the display is dim, so you almost see nothing. I use a 
reflective screen, no backlight.

Would this be my unit beeing wrong or something with the code? I tried to 
intrpet the boosting you do but not really sure i got it..

Thanks in advance

doglcd.h doesn't work with MEGA2560 (works with arduino leonardo)

What steps will reproduce the problem?
1.hook up M163 using 4 wire interface to D2-D5 on the Leonardo.
2.Assign pins and print hello world. - Works
3.hook up M163 using same 4 wires on same digital pins D2-D5 on MEGA2560 - 
Doesn't work.  Blank display

What is the expected output? What do you see instead?
Hello World

What version of the product are you using? On what operating system?
Dated 1/7/14

Please provide any additional information below.
I have created a sketch to toggle D2-D5 (digitalWrite (2,X)) and this works on 
both boards.
