I never heard about this type of cable  smiley-roll-sweat

Seems to be a Seiko G1213 LCD. See attachment for the pins...

the pins are incorrect?
so what do i do to fix it?
Difficult to say without a picture/description of your setup.

Hi

I suggest to force PSB to the intended level.
The "send()" procedure looks different than the one i programmed for u8glib: http://code.google.com/p/u8glib/source/browse/csrc/u8g_com_arduino_parallel.c.

Will your Makefile work with Serial.print?
If yes, any idea why my Makefile fails with Serial.print?

Thanks a lot for the feedback!

773  Using Arduino / Displays / Re: U8GLIB: sleepOn/Off not working on: April 29, 2013, 12:30:41 pm
These sleep functions are only available for some display types. What is your exact constructor line?

If I put a power transistor between the mega's +5v and Vcc on the display to turn it on and off will that damage the display with SDA and SCL lines still active?

Probably not, but you need to reinit the display. You can use u8g.begin() for this. All other settings are also lost...

Is there a way to reset the display system (software part), without resetting the arduino?

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.

775  Using Arduino / Displays / Re: how to show a graph on graphical lcd 240x128 ?? on: April 28, 2013, 02:14:26 am
This could be a T6963 based display, so
Code:
U8GLIB_T6963_240X128(d0, d1, d2, d3, d4, d5, d6, d7, cs, a0, wr, rd, reset)
might work.

Remember to apply a variable resistor as described in chapter 4.1 of your user manual and also select the 8x8 font for this display (apply GND to FS1, see chapter 4.3)

Hi

Für U8glib (http://code.google.com/p/u8glib/) hatte ich mich entschieden das XBM Format zu unterstützen. Vorteile:
* Standard Bildformat (z.B. Export via Gimp),
* gültiger C-Code (XBM-Datei im Editor öffnen, alles markieren und in die Arduino IDE kopieren),
* sehr einfaches Format.

Der Code zum Auslesen des XBM befindet sich hier: http://code.google.com/p/u8glib/source/browse/csrc/u8g_bitmap.c

I have updated your inital Makefile to include USB support (attached). But still the serial communication is not working. I have no idea why...

Oliver

Edit: The screen terminal emulator (used in the Makefile) can be terminated with Ctrl-a Backslash.

Hi

Your Makefile works fine. But the Serial is not activated during compilation state. If you remove the "Serial" commands from your example, then the blinking will work:
Code:
enum constants {
  ledpin=13
};
void setup() {
  // put your setup code here, to run once:
    // initialize the digital pin as an output.
  pinMode(ledpin, OUTPUT);   
  //Serial.begin(115200);
  //Serial.println("Configuration complete");
}

void loop() {
  // put your main code here, to run repeatedly:
 static bool ledstate=false;
 //Serial.print("led is ");
 //Serial.println(ledstate);
 digitalWrite(ledpin,ledstate);
 ledstate=!ledstate;
 delay(1000);
}

The PG12864 is a module, it has several parts. The T6963 is just the controller and requires only +5V to work. But the negative voltage is required for the LCD component for the display module (and yes, i think it is passed through the T6963).
Other components include segement driver and RAM. The negative voltage converter is optional and often not included.

A digramm for a module with NV can be seen here: http://www.lcd-module.de/eng/pdf/grafik/p128-7k.pdf

Hi

This is what i have seen on http://www.powertip.com.tw:
- Your display does not have the original T6963 chip but a (hopefully) compatible SAP1024B
- There seems to be no negative power converter

For testing i suggest to use an external power source. Batteries could be fine also. I have used a power supply with variable voltage output for my display during testing phase:


On the picture the battery drives the backlight. The external power supply provides the negative voltage. The red and black "Clamping hooks" provide the -15V for the contrast of  my display. Note, that the red (+15V) cable of the power supply is connected to GND of the display. The black clamp (white cable) is connected to the contrast input. The Arduino is powered by a laptop which runs on battery power. To avoid conflicts with your 220/110 AC powered devices, do use only one device powered from 220/110 AC.

Meanwhile i have replaced the power supply by a negative converting module (AM2D-0515DZ)

Please note that your display might require less then 15 volt.
