Hi Guys,
I just connected a character LCD directly to an interface that was running a similar one fine for some time.
It was just changed for a change of colour to white on black rather than the ordinary black on green ones.
The LCD ran ok for just under 14 seconds and burned with smoke, and didn’t work again!
It was a bit dark, but I didn’t have time to try adjusting contrast, but definitely readable.
I’m wondering what the reason would be for the negative supply line to connect to the positive end of this capacitor (C2).
The other side of the cap is not common with the positive. I’ve checked the datasheet, and this LCD is definitely ground on pin 1.
It has to be because it worked for 13 seconds.
I have a spare of these LCDs, but afraid to connect it or the same thing might happen.
Cheers, Brek.
