 So SPI is faster, but there is no addressing, so you cannot chain multiple SPI devices from a single set of Pico GPIO Pins. If you need to run multiple displays, your choice is to either use I2C LCDs, or use multiple sets of SPI pins for each LCD.

+Below is the driver you will need for the LCD. You need to put it in to the <color #ed1c24>lib</color> folder on your Pico.

+from machine import Pin, SPI
+from ssd1306_spi import SSD1306_SPI

+spi = SPI(1, baudrate=8000000, polarity=0, phase=0)
+dc  = Pin(13, Pin.OUT)
+res = Pin(12, Pin.OUT)
+cs  = Pin(14, Pin.OUT)
+oled = SSD1306_SPI(128, 64, spi, dc, res, cs)
+oled.fill(0)
+oled.text("Hello Alan!", 0, 0)
+oled.text("SSD1306 SPI OK", 0, 16)
+oled.text("Pico 2 Ready", 0, 32)
+oled.show()
+# call the function below from your main code with the value 255 (max  brightness)
+oled.set_brightness(255)

 I want to look at the old I2C code and compare to the SPI code to point out some differences, this is the Python code that just prints 8 static lines on the LCD for a simple test.
