Im working on a voltmeter that will requires LCD's in different spots. 2 or 3 LCD's will display the same data.
My current design has i2c oled on different addresses but wondering if SPI with clock select to few screens at once will work?

I have room for multiple CS. However I think I2C is fast enough for what I need. I was just thinking with SPI maybe I could refresh screens at the same time by having 2 or 3 CS selected at the same time.
If you have both screens at the same I2C address, and you are only writing to them, just treat them as a single display and both should show the same info.
