- 0.91" OLED 128x32 with SSD1306 driver ?
- Fuses from readme?
- R/C on reset 1000nF/27K? (if it is a SPI display)
- VCC 3,3V ?

Swap of SCL / SDA brings nothing to fry :wink:
Thank you for the help!
i ordered 128x32 OLED... i am not sure the chinese store send me a 128x64 instead...
fuses ok, i2c one, but.... i used 5v for VCC, since i swapped for testing the OLED with the LCD display!!!
May be it's the overvoltage had fried the oled... :roll:

No, this also works at 5V, but it can be the reset does not work properly.
The resolution should be printed on the display

In the I2C one's is only printed 0,91 oled... :(
I tried with 3,3v, with no change... but it's probably too late, and display is gone.
I'm waiting for a new one, arriving in a few days. Thank again for your support!

You can always verify the display using a Raspberry PI or similar... I find it very hard to believe that it would go out like that.

no, you're in error... i've found on amazon, ebay and aliexpress more 128x64 oled than 128x32, and the price are even lower!
Edit: sorry, you are right.. The 128x64 are 0.96 inch sized

In the link of first post I've added an easy experimentally way to make it with a Digispark - it's only in german, but there are some pictures and I believe that should be enough for DIY... :wink:



@aotta looks nice... :D

Projekt no longer available due to incompatibility with newer HxC-Firmware >v3.0.19.2a

The redesigned and optimized low level I2C & LCD control from v3.0.20.1a upward works not longer properly with the OLED firmware - I'm sorry, but maybe the time will bring new ideas, good luck...

Please stay with reality! My decision is based on the state of the software at http://torlus.com/floppy/forum/viewtopi ... 043#p16037 and that did not work stable again :(

Heyhey....
Just as it was your decision to take money for your idea, it is my decision to stop the spread of my idea as long as this is not proper works with your new firmware
I think that you have to respect this - or do I somewhere push a upload from a copy of your bootloader? :x

If it is tolerable again and it is stable, maybe I will release the project again...

No problem but this means that i will have to add the direct support into the firmware.
For your interest this is now stable with the 3.0.21.5a :
