Graphic LCDs / NHD-C12864WC-FSW-FBW-3V3 booster
« on: September 24, 2015, 01:21:32 AM »

Iím trying to make the NHD-C12864WC-FSW-FBW-3V3 display work and Iím having some problems with the booster. The thing is that after several trials with the 4x booster network that is suggested in the datasheet I never saw anything in the screen, however, I plugged the Vout directly with 10.5 V (typical value acording with the datasheet) and screen worked perfectly. It must be some problem with the screen or booster since the voltage value monitored in Vout when it is working with the internal voltage is about 6V. I am doing something wrong or I should give the display back?

Finally I would like to point out a mistake in the datasheet of this product, the schema depicted in page 5 has capacitors missasigned, e.g. CAP3+ is tagged as C3-.

Thanks for yout time!
