Support for 64x48 OLED ?

[erkobg]

Hello, It will be very helpful if you add support for 64x48 OLED like the official display for Wemos :+1: http://www.wemos.cc/Products/oled_shield.html

Here they did almost the same : https://github.com/mcauser/Adafruit_SSD1306/tree/esp8266-64x48

Regards!

64x48 pixel is a very common display, have you plan for support it ?

[FWeinb]

I would like to support it but I don't have one yet so I can't start working on that.

I ordered some last week, as soon as I got them I may take a look and do a PR. @FWeinb is there any tip should I know for being able to change resolution on library, such like current 128x64 resolution hard coded somewhere? may I just change then and OLED init code ?

[FWeinb]

To get this working you need to change the defines here and introduce a custom constructor/subclass of each driver to allow for selection of the width/height. Than you need to introduce local member variables to contain the width/height in the OLEDDisplay class and change every access to the defines to use these new local variables.

Being a lazy bastard, I took this lib and instead of adding support for different display, I just made it work with 128x32. Then to be a complete *hole, I took the latest version, dropped changed files over it instead of merging. But it might be still a useful starting point for your own changes - feel free to see diff and find what's needed to make other geometries work.

I've submitted a pull request https://github.com/squix78/esp8266-oled-ssd1306/pull/97 for changes to allow use of either 128x64 or 128x32 displays based on LimaLima's changes (thanks for working out the register values, I don't know what they do, but they work for me!)

@FWeinb: to understand the tiny 64x48 display a bit better, refer to the following stuff

// cf. https://www.wemos.cc/product/oled-shield.html // cf. https://macsbug.files.wordpress.com/2016/04/zahyou_s.png?w=700 // cf. https://macsbug.wordpress.com/2016/04/01/using-the-wemos-i2c-oled-64x48/

Sorry - the last link goes to a japanese site, but it can be understood pretty good due to the well documented code examples in english, good links and nice pictures... (I like this stuff)

BTW: Thanks for the New Year stuff :-)

I fixed that issue for a OLED 64x48:
