Ampire AC162AY or what can go wrong?
I have spent some time to get the proper pin layout for the 16x2 LCD from Ampire (the model is AC162AY, or 162A-1-D Rev.B). The problem begins with the different polarity of the power rails. I thought if the polarity is wrong, what else can be wrong? That's how I started my search on Internet without any positive results - all of the layouts have a standard power rail polarity, i.e. 1 - GND and 2 - Vcc. At the end it comes I wasted time. Only power rails are messed up, other than that everything seems standard and I got a text on the LCD.
P.S> Found a PDF with photos of that LCD: https://fccid.io/W8F800920910/Internal-Photos/Internal-Photos-2-1406623.pdf
