Hi E and J,
The module started showing MOSI after I cleaned it for the photo
Here's the circuit: (Test circuit that has been modified and re-worked)
Here's the readout from #74 Zoomed in and out.
The back light is on. My schematic shows connect the LIGHT PIN to GND. Previously on the 4x20 LCDs they had a POT for contrast, do these need a POT?
18F and LF the same in this sense, noted.
