Yes the reset pin is the same on all my projects. I’ve also tired the EG code for displaying A on the LCD and that isnt working too. The 16×2 displays boxes on the first line and nothing on the second. Then I tried replacing the cap on the circut, the crystal and the power wires along with programming the uC again but that didnt work either. So then i checked if all the pins on the LCD were receiving electricty so with the help of an Led i check each pin, all good. So now i have no clue what the problem is, I’ve connected it in 8 bit and 4 bit and tried all sorts of code.
