Hi guys,
im getting ready to place an order for micro displays for future projects. Most of the sizes come on the ST7735 chipset, which can be found on libraries.
But i have the need for a 1.1" square full color display. I have only found one version that comes SPI ready with 7 pin connectors, and it runs on an LD7134 driver chip. I have not been able to find anything on that driver chip, and also no library that is documented to support it.
There is another version that uses the SSD1351 which is supported by adafruit, however it comes with a 34 pin FFC connection which i cannot work with.
Can anyone give me a heads up wether or not i will be able to get the LD7134 on 7 pin SPI to run?
Thanks from a display newbie
Please post links to the actual items you want to buy.
The LD7134 is only 96x96. And it has very different registers to the popular ST7735 controller (132x162)
It should be easy to write a suitable library for the LD7134.
It is more difficult to connect to a small ribbon.
It is even more difficult to convince an Arduino user that a 3.3V chip requires 3.3V GPIO signals.

Attached i found the spec sheet for the chip. It still does not help.....
The 1.12" display is only 96x96.

How would a library for this look?
LD7134_Spec Ver3.0_110918.pdf (832 KB)
That particular display can be connected easily to a 3.3V Arduino.
OTOH, you could buy a SSD1331 OLED (96x64)
or a SSD1351 OLED (128x128)
The Solomon controllers have several proven libraries.
But there are tens of TFT controllers in this size range e.g. ST7735S
and the displays are cheap.
There are ST7789 displays with small screens.

Yes, but i need the 1.12".....a 1.3" is too big for my use
Yes.....the 96x96 is the 1.12". It has an LD7134 chip......now to square 1 where i need a library for that
There is no library that I can find.
Ask the vendor for some example code.
I can "guess" suitable Manufacturer commands e.g. for setting display currents.
But I can not see the result without the actual device.
Do you need full colour?
An SSD1306 128x64 would work out of the box.
David.
I have asked all dealers and manufacturers, but there is no library for arduino on their side.
I need full color, and i need the 19,8*19,8mm active area because this is what fits the bevels.....the 24x24 are too large and will peek over the sides....thats why im not looking for any kind of replacement, im looking for exact this screen size.
