I'm confused about how to do the backlight for this display (I did read the datasheet and search the forum). I get that it wants 30mA but what's on the other side? A single LED, a series of LEDs, or a just a resistor like I saw in the previous post?
I'm going for an always own backlight so if it's just a resistor I'd guess I need about 3.3V ->10 Ohms->A, and then K to GND for full brightness?
