Im working on a project which requires multiple OLED modules (hopefully 8 of them) running on a MEGA. So far I’ve got one OLED working fine .
This is the one that I’m using: 3-5V 0.96" 12C Serial 128X64 OLED LCD LED Display Module for Arduino White foUK | eBay) .
but I’m aware that I can only have two of these running at once due to the fact that they only have two address options (selectable by moving the 0 ohm resistor on the back of them). So I’m now wondering if i can demultiplex the signal from the scl and sda pins using this module: -
alternatively I’m wondering if using SPI OLED’s (as opposed to I2C) would allow me to connect more without the need for a multiplexer module but at the expense of extra digital pins. Is this how it works?
