While I loved the Nokia 5110 LCD’s readability in full sun, the pressure sensitivity was a real problem for the underwater units. So I started noodling around with some cheap OLED screens from eBay.
With the exception of the init & XY functions (which are more complicated on the 1306 controller) the rest of the code ported over from the Nokia screen with no changes at all. My guess at this point is that the shift-out method will work with most of the other cheap OLED screens, provided they don’t exceed the pin current limits implied by my method.
