Recently I've bought the Picaxe033 lcd display. I've assembled as per instructions but the only thing that I've got out of lcd are black blocks.
I've tried to adjust the contrast pot, no results.
I've checked the connections, soldering, all good:
pins 1, 5, 7-10 to 0v
pin 2 to 5v
pin 3 to pot
pin 4 (RS) to 8 (PIC16...)
pin 6 (E) to 9 (PIC16...)
pin 11 (DB4) to 6 (Pic...)
pin 12 (DB5) to 12 (pic...)
pin 13 (DB6) to 13 (pic..)
pin 14 (DB7) to 15 (pic..)
or at least that's what my multimeter says.
I've read first 6 pages of search results about axe033 but still no answer.
Any ideas? The last 3 days were very frustrating
