 On the Zero, the SPI bus 1 pins are not exposed, so it cannot be used.

+==== The Wiring ====
+\\
+The wiring for the Zero is exactly the same as for the Pico, unfortunately there are two slight differences.
+  * 1. The GPIO Pins are different.
+  * 2. The Pico uses SPI1 and the Zero uses SPI0
+See the wiring below:

+Once you have wired up your LCD, we can move on to the software.

+----
+==== The Driver ====
+\\
+You can download the driver here: {{ :ssd_1306_zero.zip |}} you have to upload the driver to the \lib folder.
+\\
+\\
+I am not going to talk about the driver because there isn't anything in there we need to change.
+\\
+\\
+----
+==== Test Code ====
+\\
+All this test code does is to print 8 lines of text with sequential numbers after them, the numbers keep incrementing one at a time. The test code is designed to ensure the LCD is working fine, not to provide any real functionality, that will be up to you once you get your LCD working.
