Hello
How to get ssd1306 oled display to work in a same solution with digital in and out.
Both works in its own solution, but not together each others.
Looked like they are both using same clk and dma?

they all use same i2c bus, but they have different i2c address. why can't work at the same time?
do you use esphome or arduino code?

I’ve been using arduino code

check your code, it should be work at the same time.
