[rezaaghazade]

hi body. i want to use your luma.oled example, but i have a problem when i run the code, display bellow 👍

Display : pcd8544 Interface : i2c Dimensions : 128*64

---

my display is not pcd8544 how can i change the display to what i use ?

attention : my oled worked with AdaFruit Code, but not work with your code https://github.com/adafruit/Adafruit-Raspberry-Pi-Python-Code

Hi, so what type of device have you got, and do you know its model number? If you aren't sure, please take a photo (of the front and the back of the display) and drag it into your reply.

and what is the python command you are running? I am assuming you are running one of the examples, but I need to know which one and what flags you are supplying.

this is my oled, i think this is ssd1306 128*64 (2Color)

and about a command i use : i use simple command 👍 python yourExampleName.py this code work for another example except yours

Ok, so it looks like a regular 128x64 SSD1306 using I2C - this is probably the most common device and is fully supported.

Check to make sure you have installed the luma.oled package from pypi:

$ pip list | grep luma 
luma.core (1.0.1)
luma.emulator (0.2.5)
luma.lcd (1.0.0)
luma.led-matrix (1.0.2)
luma.oled (2.2.10)

Your list might be different, but you need to ensure luma.oled is installed - if you can't see it, try installing again with:

$ sudo pip install -IU luma.oled

Clone the http://github.com/rm-hull/luma.examples repo if you haven't done already, and from within that directory (any of the examples should work the same):

$ python examples/clock.py -d ssd1306

Look at the source code and the docs (https://luma-oled.readthedocs.io/en/latest/python-usage.html) for how to use the classes in your own program.

thanks alot, it's worked

after all these, i have another question, my oled is 2 color, 2 color means every pixel can show 2 color ? how can i change these color (with your code)?

[rm-hull]

I have a device exactly the same as yours - it has a yellow band at the top and and the remainder of the screen is blue, and i originally thought that each pixel color could be programmed accordingly but it is not possible - the SSD1306 is monochrome, presumably there is a filter of some sort built into the display.

There are other OLED displays which support full color, eg the SSD1331 - also supported by this library, and works in full color.
