So im trying to give my lcd display (Lumex 1602) 5v. Im trying to use the test pins on my msp430 launchpad TP1 and TP3.
On the LCD pin 1 is gnd and pin 2 is power. for the launchpad TP1 is power and TP3 is gnd.
nothing lights up after plugging in the usb cable. Does mine just not have a backlight in it? How can i test to make sure its getting power and that it isnt broken?
*Edit So i got it to light up! Heres how i wired it: LCD Pin1 to gnd LCD Pin2 to pwr LCD Pin3 to Potentiometer. This is what drives the LCD display.
I used TP1(pwr) and TP2(gnd) which are test pins on the msp430 launchpad and provide me 5v power.
