Question So when you buy the screen Does it come with an accompanying board for the ribbon to attach to for wiring it to the Gotek?
Yes, the OLED screen typically comes with the board (although, some you can get separately, I believe). However, only some comes with a frame and a detachable ribbon, which is a requirement for this solution.

See the various OLED screens I have tested with the Gotek:

Thanks. Solarmon, with these settings you told i got only the lower 2 blue rows as i mentioned before, but not the first yellow one. I'll try it tomorrow again with new copied ff.cfg and changing the settings again. Trackball is working without any problem as a normal 2-row display is working without any problems.

FlsshFloppy may be caching your config.

You can reset it and get it to read the config file in again:

Thank you for getting back to me, another question so from looking at the link you provided I would have to modify the larger screens?

Yes, if you want to mount it on/through the grill of the Amiga 1200 (or on top of the Gotek), I find the 2.42" DIY More screen the easiest to mod.

Thanks but I just read the changing of resistors, my eyesight and my soldering skills are not the best so I will leave this one for the time being.

Everytime you power-on FlashFloppy it reads the config again, no need for reset but i've tried this too and all the same. I'm going to send the pictures to Keir, maybe the firmware needs some corrections.

Join the FlashFloppy Facebook group and post the issue, with pictures, on there.

No. This doesn't work how it should. Somthing in firmware is wrong i think. Config file is correct, it should work. I don't have facebook and i don't have a github account to post it there. 2 row display is working fine. I'll waiting for the 3rd 128x64 OLED and will check again. First doesn't work at all (exactly the one whats on your list you've posted, i think its damaged from transportation), second the one what i posted here and third will be the next surprise. If this doesn't work too i'll never try those again, don't have the time.

This is the one which is not working right, i can't get all 3 rows showing on the display:

Send me your FF.cfg file (put it in The Zone?) and I will try it out.

The only difference I can see, is that you have a two colour display - the top x rows are a difference colour to the rest of the screen. I don't know if this makes a significant difference, but I have not tested these types of OLED screens.

Maybe I'll get one myself to try out.

And my 128x64 0.96" OLED screen (not exactly the same as yours, looking at the back of it) is working fine with three lines, using FF 3.2a:

If i change display-order to '3,0d,1' i see only the yellow first row and not the others.

With the same display and your cfg it doesn't work at all!

The other display i got is the same as yours (back of it is exacty the same) but doesn't work at all with my cfg, maybe dead by transportation. Haven't tried your cfg with this yet.

My Yellow/Blue 0.96" 128x64 screen came in.

It's not quite the same as yours:



But it is working as expected, with three lines:



Using the following settings:

Code:
display-type = oled-128x64
Code:
display-order = default
The only differrence (apart from a differrent board) is that your one has an SCK pin instead of SCL, but I think this is the same thing, as otherwise you would not be getting anything on your screen.

Where did you get your OLED screen from?

SCK and SCL should be the same thing i think, btw. on the FF github pictures it says SCK...so 100% correct anyway.

I've ordered it from WAVGAT store:

0,96 zoll IIC Serien Weiß OLED Display Modul 128X64 I2C SSD1306 12864 LCD Screen Bord GND VCC SCL SDA 0,96 "für Arduino Schwarz

Where have you ordered yours? So i'll give it a try i think.


I have a question, the middle row is bigger than the others on your display. Can you change the config to get all 3 rows the same high? Or the upper row bigger and the lower 2 rows smaller but same high?

Where are you seeing 'SCK' in the FlashFloppy Github pages?

This one you linked to does not seem to be the one you showed previously - the back of it is different.

I one I got is from a UK seller which I just chose for quick delivery for me:

https://www.ebay.co.uk/itm/128X64-0-...72.m2749.l2649

But any 4-pin I2C OLED display, that is single or dual colour, should work - so I'm not sure why yours is not working.

Sorry for late reply.

That from wavgat store doesn't work at all, and my other two ones (same components on the backside) only showing what i described before. In total i have 3 of these 3 row displays now. Hm, can't remember where i've seen SCK, but should be the same.

The one you've linked doesn't ship to my country.

I give up and sadly have to use the smaller 2 row display. There is nothing wrong with my setting, it's either not compatible OLED due to different layout/components/ControllerIC or something not good with FFfirmware.

Maybe i'll use the new addon with onscreen display.
