I'm currently working on a side project which uses an SSD1306 128x64 OLED display. I'm then using I2C to communicate to this.
However, I'd like to better understand what exactly is going on when I'm writing values to the various registers.
From what I've read I believe these registers can be re-mapped inside the device so they might not be the actual register addresses that I'm writing to.
For arguments sake, say I was writing to the register itself, what is happening in the chip? Does it get used directly as part of the logic within the circuit - one of the bits as the input to an AND gate for example?
