Cool - I'm getting them tomorrow so I'll give it a try. Thanks Guys

Hi There,

I'm planning a project with a 4 line LCD. These are the only ones that I can find locally. I've been looking through the datasheet and it seems hd44780 compatible, but I'm not sure. Can somebody check the datasheet and just verify for me that it will work.

thanks for the info. thats exactly what I was looking for.  smiley

Hi There,

I'm relatively new to i2c, but this is what I want to try and do:

I've got a little controller that I can program to send i2c commands. What I want to do is to connect my arduino board to the controller and receive those i2c commands. How would I connect it to my arduino? I've got three pins for i2c communication SCL_5v and SDA_5v and GND. If I can get it connected are there easy commands to read this i2c input ? Any help would be greatly appreciated and I'll make everything I get to work freely available on the net smiley

Will this work on the atmega8 ?

has anybody got this to work on the atmega8 ? I tried the cli method and the pong intro screen shows fine now, but when the game starts it gets out of sync again .

Ok ignore what I just said in the post above.  cli(); in set-up works just fine.
I was running software version 0007, I just downloaded 0009 and it all works fine now.

I can play pong now, my life is complete!!!

Thanks for sharing a great project.

Are you using arduino with an atmega168 or atmega8 ?

Heres what I get (on the 168) when I don't disable the interrupt


If your getting something similar to the first img, try the cli(); method.


Your photo pretty much shows the same problem that I'm having. I'll try it again tonight on the atmega8 with the cli() method.

Very nice! I tried it tonight but with not much luck. BUT I don't have a 75 Ohm resistor so I tried a 68 and 85 resistor. I can see that the program is running, but it's jumpy and not very much in sync. Is it possible that this happens because I don't have 75 ohm resistor ? Also, you mentioned something about disabling the timer interrupt? Is this only for the atmega168 ? I'm running it on an atmega8.

We have PAL tv's here in South Africa so thats not the problem. Any information would be greatly appreciated. Once I get your example going I would like to try and get something like tetris or even snake going smiley

Wow, those are pretty cool silkscreens macegr. Which software do you use for designing your pcb's and silkscreens ?

great board, any chance that this can be done a singe side board for home etching?

wow, that looks amazing. I'm very interested in your project. Are you planning on making schematics and code available ?

Mind sharing a schematic for your synth ? I'm not a musician or anything like that but I just love the sounds from your sample and would love to try this.

Saving money by making the board and sourcing your own parts will take time, so it's sort of a matter of what you think your time's worth.

I've sourced all the parts for this and I am planning on making my own board (not that I think it is expensive, I just enjoy trying to make my own stuff), but has anybody had a chance to make a single sided pcb ?

very cool project. I've got an old gameboy lying around somewhere and I would love to have it communicate with an arduino, although maybe not via djing software.

Any hardware you can recommend I get to start playing around with interfacing my gameboy to the arduino ?
