B4R Question SH1106 1.30" lcd display issues

[Cableguy]

Hi EREL,

I Have a SH1106 based LCD display, which I got working to 80% (see the image)

My 2 issues are:

1 - position 0,0 is shifted to the left about 4px and thus a 4px wide Vertical line appears in the right side.
In the image a part of this line is erase by the space occupied by the text.

2 - I need to show graphics in this display and as it stands today I can't see how.

I am using the SeedOLED + Wire libs to make this one work.

Its a 4wire IIC display with no address setting.

So, any chance to update this LIB to lattest versions?

Hiya @Cableguy,

Hmm, I have a few of those LCD's and I've not come across that issue. I'll have another look at it later when I'm back from my 34 mile bike ride as I'm not sure if I've ever actually tried setting text to display at location (0, 0).

This seems to be a known issue with some lcds with this particular chip.
Take a look at this discussion.
It looks like I would need to change a shift setting in the lib itself, but I would prefer to have a properly working lib.
Also, I will need to do some graphics on it, so if you have any info on that, I will appreciate it.

I've just seen this quote in the link that you posted "I think your display really has a SH1106 controller. It is similar, but not identical to the SSD1306".

I know for a fact that I have the 1306 controller even though they look identical. I'll be back home in an hour, could you send me the code that you are using?

Cheers...

 

[Cableguy]

I just copied the example in the u8glib thread and added the lines

Hello cable guy,
I can confirm that it's working perfect with my 1306. I thought that I had an 1106 but I can't find it right now, that's if I have got one.

Is there no library for the 1106, if so you could always just use inline c like I did here because the standard libraries on the forum don't work with the esp32 in this link and the standard library is missing some features too https://www.b4x.com/android/forum/t...-in-oled-display-progress-bar-inline-c.81391/

 

[Cableguy]

Thanks for testing... I will try inline c and maybe convert a code module into a usable lib

 

[Peter Simpson]

Here is the 1106 library if you need it https://github.com/wonho-maker/Adafruit_SH1106

Example code: http://github.com/wonho-maker/Adafruit_SH1106/blob/master/examples/sh1106_128x64_i2c/sh1106_128x64_i2c.ino

Just use the c functions that you need and scrap the rest, that's what I do. But hey, I don't need to tell you that


Enjoy...

 

[Cableguy]

Thanks

Have you tried this library examples with Arduino IDE: https://github.com/wonho-maker/Adafruit_SH1106 ?

I already posted that link 3 posts above. You take one day off and you slow down to a smails crawl

 

[Erel]

I saw your post. I wanted that Cableguy will confirm that it works...

 

[Cableguy]

I'm having some difficulties compiling and uploading with arduino IDE. I'll keep you posted

YES, YES, IT WORKS!!!

I just managed to make it work with the Arduino IDE and the example (i2c version) provided inside the lib.
No shifting and no vertical line!

EREL, I can try to create a code module and convert it to a lib, but it would be so much more elegant a proper wrapper.... please????

 

[Erel]

I will create a wrapper for this.

 

[Cableguy]

I will create a wrapper for this.

Any ETA on this?

 

[Erel]

Hopefully today.
