Hi guys, it's been quite a while!
I've salvaged two 16x2 LCD parts, with the label BMX-01 and E226252 on the back, but they don't return any proper searches. However, I do believe the structure is pretty generic like other 16x2 LCD displays, so I just want to confirm whether the pinouts are correct as shown in the attached figures:
View attachment 67082
View attachment 67083
So I *think* the designated pins are (starting from the left, as shown by the first figure, top view):
1: GND
2: 5V
3: Vee (Contrast)
4: RS (Register Select)
5: R/W (Read/Write)
6: EN
7-14: DB0-DB7
15: LED+
16: LED-
However, the functionality test (to show all black boxes) wasn't successful so I'm rethinking my pin assignment. *If* going by the usual structure, are the pinouts correct?
Thanks everyone.
