[graymalkin1234]

@itsmeohmeandme Yeah, what have you done with it so far? Anything?

[itsmeohmeandme]

I got it to print to the lcd through what i type in the serial monitor but ya nothing really?

[Scorpion7substance]

well done, can you make it do drawings too like faces?

[RobertEaglefy]

what about processor and pagefile.

How can i find the CPU status and pagefile status?

With what code could you?

CAn you give me an example to understand?

[davorb]

Where can I find the "modified version"?

[Masterune580]

wicked.

[tocomeko123]

Ouch, nasty ghosting!!! Nice set up though

[fshanahan]

Thanks. The ghosting is just a video artifact, it's not really visible in real life.

[tocomeko123]

In that case just nice set up!! :D

hi there,, I recently purchased the exact same lcd character display that came with a usb demo board and a single row pin header. Ive been trying to program the demo board to display messages on the lcd screen but no success. Can you help me out please if you can.. IVe provided two links that relates to my products. thank you very much. this is a link below ive typed it this way so it would allow me to input it on you tube. thanks .sure-electronics. net /mcu,display /DE-LM005. pdf

awesome!

[dorilx]

this is a nice setup, but isn't it simpler just to connect the display straight to the pc and control it directly using a software? what is the benefit of using the arduino for this purpose, or is it just a proof of concept? thanks!

[fshanahan]

Yes, absolutely, this could've been connected directly to the parallel port. I just did it this way to use a USB port and the get familiar with the arduino. See my follow up project which is a more complex LED matrix using an RGB matrix with 192 LEDs.

[fshanahan]

I used the 4 bit library but first got it working with 8 bit. What kind of problems are you having?

[kingarthur1985]

Did you use 4bit or 8bit....... i just can't get it to work for me.... man it has been four days in a row with no luck. Would you please share the library and the programing that you used.... LET US BENEFIT FROM YOU WORK. thanks
