thats the same i saw too.when i look at the datasheet on it
I found out is hard to write the code for I2C buss
on that display you couldnt get working it kinda easy to get info on it,if there is a chip #,i forgot the most common chip used for lcd displays using I2C buss ,and then from there can find another display that uses the chip and get the I2C buss info.
Called backwards or reverse engineering,i do it alot at work from other designs others make ,not lcd
but electronic testers,from my head i know most circuit and how they are design along with photographic electronic memory i have.
It was the LCD display that's been mentioned on here a few times in the past, DJ has even looked in to it without any real results. A long combination of I2C codes needs to be sent to it in a specific order for it to work and without the datasheet and literally hundreds of thousands of combinations it's not worth the bother. I spent the best part of a day just trying combinations of code that was found in scripts for the Arduino with very little sucess.
I2C is as easy or as hard as the I2C device and documentation allows it to be. Poorly documented I2C devices are a nightmare and near impossible to use but well documented devices like the BlinkM look simple to use.
I guess you didnt try me on the lcd,i would find the answer on it.
For the right I2C code you need the main chip # a nd then the code for it kinda easy to find it,i done it many times ,not yet on LCD only because i dont use them,i buy a lot of surplus stuff and none can get a data sheet on it,with reverse engineering able to use it,and using good test equipment too
My topic is here
The only information I could find is here
There are a few other forum topics about it that I found when searching but nobody could get close to having it usable in ARC/EZ-Script. Feel free to try though, I'm sure more will attempt it as it's the cheapest LCD out there (and now I know why).
Here is a idea that works for me everytime,look for lcd with the same chip # and they would have I2C commands,i would buy the lcd and test it to make shore my commands work and then try on one that i have that has no info. and it will work.
havent tried it with LCD yet since havent use one ,but other stuff yes it works.
The chip has the commands built-in ,and you cant program it,its same for any lcd,commands are always the same,they dont change from one company to another.
If its using a microprocessor then its different,they change from company to company.
At my company besides electronics designer i am one of the best troubleshooter.
Thanks I got them working. I tried a script changing colors after a sleep for 5 sec, but for some reason it will only display one color and not the other ie go from red to blue. But the sliders are great in EZB for setting colors. I'll dive into it a bit more when I have more time. But again thanks for all the help.

But they are cheap about $10,

i wish i saw it i could mostly help,but you trashed it,but if someone gets it i can takea look at it
I HAVE lcd that uses that same chip and with data for it too,with I2C commands
