OLED is quite good, anyways as this is I2C control nothing change except enclosure and PCB.
Code is not finished yet as I want to add some more function like open/close comport to avoid potential conflict when running Gcode from computer ans also for security, play different sound on the RAMPS LCD buzzer…etc…
I just finished the schematic and PCB design is on the way with the 0.96 OLED.
If you want to use my firmware you need to find OLED I2C with SSD1306 chip, which is, view from here (In China) not so easy to find as more common are 0.96 or 1.3 with this driver.
One of the problems I had to face was to find a small footprint library for those OLED ( ADDAFRUIT has one excellent but burn all memory just for the screen…cannot do anything else except beautiful screen with that one on those small AT328.
I try with 1.3 and 0.96 and keep on the 0.96 because it was matching DUI’s enclosure with minor modification, I didn’t feel this too small as this is on the remote so close to eyes (even with glasses like me and OLED provide excellent contrasted characters.
here is my schematic for your reference.
