No, no need, i can reduce the character spacing, this is just a setting.

Two firmwares :

Full display OLED firmware :

"Narrow" display - shorter OLED character spacing

But is not the same font you used on your oled project?

I use the second (7x16) it's the maximum who fits in the window

Of course, the 6x13 is also readable without (my) glasses, due to good contrast of the OLED

i have not yet tried the Jeff beta, but with yours i could read fine the lines on the OLED, also without the glasses i started used when soldering thin wires. :lol:

Some instructions to connect the oled screen.

I2C SSD1306 128x32 OLED LCD Screen :

Code: Select all

Note : Since the 3.0.26.1a

  You can connect an SSD1306 based 128x32 OLED screen.

  These screens are compatible with this firmware : http://www.ebay.com/itm/302110929185  ( IIC Interface ! )

  You can connect the screen directly to the J7 connector. (additional pull-up resistors NOT required.)

 - GND, VCC 3.3V, SCL and SDA position on J7 :

                           _____|
                          |     |
                          | USB |
                          |_____|
        OO______________________|
    SDA OO|SCL
    GND OO|VCC3V3
        J7|
          |
__________|

! > Take care with the 3.3V and GND while connecting the screen. Any mistake may damage the screen ! < !

I've put together a design for a 3D printable replacement casing for the Gotek drive. Here's a preview. You should be able to generate either a full box + lid, or a "frame" that includes a face plate, the supports for the board, and enough of a skeleton to give a reasonable amount of rigidity and the usual mounting holes that are found along the side and bottom of a floppy drive.

You can also:
  1. choose between support for the Gotek drive's own three-digit LED display or a 0.91-inch 128x32 I2C OLED module
  2. You can further change the overall width & height of the bay, offset the mounting &c so that the USB connector is not in the center, and add extra space between the display and the USB port
  3. Choose between 1 or 2 LED holes, and 2 or 3 button holes
  4. Specify the thickness of wall and floor/ceiling material, for example to adjust to printers with different nozzle sizes
  5. Add 'extra space' to all holes to compensate for over-extrusion on your printer
I printed one today as well, and took some pictures:

it came out quite well. As you can see, the OLED display is nicely framed, aligned with the USB connector, and with the entire display area visible (though the firmware running on it at the time uses a smaller font). There's also a hole for the third button, but I still have to put that in place.

Best wishes
