Agreed..
But PreenFM1 use 8 bits communication and PreenFM2 4 bits.. which makes the comparison not straightforward.

Altitude:
umph, that's bad news.  I could never get it to work in 4 bit mode on a midibox project but I am far from qualified to debug something like that.  Hopefully you will have better luck

Here is an article about the changed init code: http://www.elcojacobs.com/controlling-an-oled-character-display-with-arduino/

Xavier:

Thanks a lot for this link  :)

Xavier:
Firmware 0.9d + bootloader 1.01 have more conservative timing and should work with more (all ?) LCD display.

Let me know if it works for you
