Topic: LCD shield and/or LCD serial backpack (Read 34 times) previous topic - next topic

I tried reading the previous.. 6 pages.. haha got a headache! So hopefully this wasn't discussed too much, but,

Is there a library for this? I'm looking to turn my Atmega 168, or 8 into well, an LCD controller that works via Serial. (I don't really need I2C or SPI, just seems like more unneeded code!:D)

I did see most of the serial backpacks use the PIC16blahblah, but I'd prefer to stick with AVR.

But I agree, count me in for one!

Well it's not an arduino LCD shield but it is cool with the controller and because it's from sureelectronics it's really cheap!

I like it! :D

How does the backlight work on these LCDs?  Is it a pair of coloured leds?  I've got a backlight from a broken LCD (the backlight still works) but it looks different to the nuelectronics shield backlight, the busted one has a single anode/cathode pair of pins that are on a white bit of plastic that is the base, the nuelectronics has 2 pairs of A/K and look like they go into to little square lumps of plastic (like leds :D) .  

The busted one looks like an EL panel style light box, although I thought they need specific power supplies for driving them, I just connected the AK to a pair of 5v with a resistor. I don't want to destroy it as it can be used elsewhere but i would like to know about swapping out either the whole nuelectronics backlight or if it simply means replacing some leds that would be cool as I'd prefer a red backlight  or maybe even break out my own RGB kind of thing for it (red for protecting night vision as bright green/blue light is a pita for astronomy).

They are normally tiny surface mount LEDs on the bottom of the display with a diffuser... They are not easy to replace.

Yes, red is best for astronomy... :D Just out of interest, what is the astronomy project? I haven't seen many around...
