Thanks guys for all your help. Finally i turned ON some pixels on the
graphic lcd by changing some initialization commands.
But it is not clearing completely.
|
Just a tip. Be more exact. We are not mind readers.
1. Post your new init code.
2. Post a photo showing what pixels are turned on. |

How to turn 8x8 pixels ON?
How to select the page address and column address? |
Hi, I'm having the same problem you had. I can't display anything on my display. My pins voltage values are almost the same.
Can you please share what changes did you implement to your initialization commands?
thank you |

In a previous thread, you were talking about using an OLED. Now you
want help on a GLCD. That's what this thread is about.
If you want help, post:
- Your PIC.
- The manufacturer and part number of your display.
- A list of all connections between the display and your PIC.
- The Vdd voltage of your display and your PIC.
- Post your test program and driver program (or post a link to the driver).
- Your CCS compiler version.
- Etc.
In other words, give us full information and we may be able to help you. |

As said, I am having the same problems as Henmath had, that is why I quoted his comment.
I am using the same code as he did with his same display with the same controller and I get the same voltages on my pins (40-21) as he did. My pic is a 18f2685 . The display is a EA DOGL128W-6 with a ST756R controller (SPI). As Henmath was able to make his GLCD display something I want to know what changes did he do to his initialization code.
Thanks |
