Why have I got "Unable to open connection ... Host does not exist " error message?
If this happens it can be complicated to debug, first go-to your router settings and find all currently connected devices. The method of doing this will differ depending on your router, but instructions should exist on the router it self or online. If you do not see a device called "raspberrypi" listed anywhere then it has not connected to your WIFI correctly.
In which case you will need to unplug your Pi, wait 10 seconds before removing the SD card and then reinsert it into your PC again. You will notice your two new files have been removed; this is normal. You will have to remake them as they are moved from the boot partition into the "hidden" partition every time you turn on your Pi. When remaking your SSH and wpa_supplicant.conf file take extra care to ensure they match the requirements. Capital letters and spacing is important! I would also suggest moving closer to your router and using the 2Ghz band if you are not already doing so.
If you are still having issues you could attempt connecting via ethernet, via USB or as a last resort you may need to buy a mini-hdmi to hdmi lead and a way of connecting a keyboard to your Pi directly to debug the issues easily. This should not cost more than £10.
To connect the display to your Pi please refer to both the diagram and the table below, taking extra care to make sure you have both in the same orientation as the shown so not to wire up the device incorrectly. Incorrect wiring up can cause permanent damage to the display and/or the Pi. Also do not attempt to wire up the display while the Pi is turned on. If you have opted for a header-less display and Pi you will now need to bring out your soldering iron. If you have opted for a headered display you just simply need to push the wires into the correct pins.
OLED Display Pins : 1,7,8,9,10,11,12 and 13 can be connected to the Pi Zero Pins: 6, 9, 14,20, 25, 30, 34 and 39 in any combination.
Those display pins simply need to be connected to any Pi ground pin. The Diagram below will show one possible combination. Where all OLED Pins are connected to one Pi Zero Pin 6, but if you want you can connect one OLED pin to one Pi pin of your choosing.
|Pi Zero Pin Number||OLED Display Pin Number|
|6, 9, 14,20, 25, 30, 34 and 39||1,7,8,9,10,11,12 and 13|
