Hello,
I'm new in the electronic's world.
I'm going to get four Graphic I2C of 0.69" and I would like to know if I can align the displays in a row and program them as if they were a single display.
I don't know if it will work just sharing the connections of each pin. I would like to show up a long line of text through the whole line of display.
I have an Arduino Uno to program them.
Thank you.
Hi and welcome.
In theory you could do what you are asking.
But if you have to ask, that suggests very low experience with such displays.
That doesn't help.
There's a few things to take in to account.
First, displays aren't borderless.
Most (if not all) displays you can use with Arduino also are mounted on PCBs which are larger than the display itself, in all directions.
So there will be gaps where nothing can be displayed.
Lots of displays have select pins.
You could connect all other pins together and just have those select pins unique to the display you need to control.
This is known to be done for 2 displays, i don't know if one can get away with four displays this way.
Also you need to control a lot of pixels.
If you are thinking of using larger displays with a large amount of pixels, you will get into some memory trouble.
And you need to break up whatever you want to display, into the 4 sections.
That's quite a lot to handle, certainly if you are new to all of this.
