  • Oh, it looks like this LCD has a back light, don’t i feel stupid.

  • I bought this LCD, but it is almost impossible to read. It is not nearly as bright as the one in the picture on spark fun. I tried adjusting the contrast to no avail. Am i doing something wrong?

  • This LCD is a lot brighter if you swap the 100ohm (R7) resistor on the back with something like a 10ohm.
    I had the same brightness issue others seem to be having so I checked the datasheet. The backlight LED has a pretty high forward voltage and current that the included 100ohm doesn’t really drive from 5V. With 10ohms, the current draw is more like the datasheet spec - 90mA at 5V.

  • for PIC directly, but you can implement driver for any microcontroller easily using mine as a base…
    its just digital output high/lows so lol

  • Lucky for me my LCD happened to have other unexplainable problems by Sparkfun’s tech support. They offered me a new LCD so I will be getting the white on black version. Sparkfun’s techsupport and customer service are the best I have ever experienced!

  • Sparkfun tech support was super helpful, no complaints there, however if you can get the LCD this bright then it is your lucky day because my product is barely readable :( Might try the white on black LCD?
