i wondering how traktor dj softwear is comunicate with the oled display that are built in to some of there controlers. all the buttons and knobs, are assume are comunicate with the midi protocol.
but how lcd is working?
for examle, if connect oled display to arduino how i will make the oled to display time elapse, or the wave form e.t.c any idea?
It depends on the oled screen. Some use SPI, some i²c, some may even have parallel interfaces. But it will certainly not use MIDI.
Is this an Arduino related question?
for sure they not use midi..
well actually is not arduino 100% question, but it can be.
imagine that you want to use arduino, to add a display on in, and then to make this display to display data that a softwear provides. lets say you wann to display the wave form.
or the bpm tempo e.t.c take a look at the picture.
is this possible or is out of arduino capabilities.
Depends on the “Arduino”. An Uno can't, but some higher-end Arduino-compatible boards (e.g. Teensy, ESP32, some STM32) should be able to do this without issues.
However, the protocol they use is most likely proprietary, so you'll need to reverse-engineer it, which might not be a simple task, and you'll probably run into limitations of the Traktor software.
