Which library do you use for SSD1963, at 16-bit parallel interface?

Quite challenging driving a display with this interface

Sadly no answer.

@@yasyasmarangoz3577On most controllers you have Pins that you can pull up or down to choose between for example 8 or 16 bit mode. So you can control the display with 16bit parallel for best performance or because you dont have that many pins you can choose to use 8 bit

Hello MisterkeTube, I don't know if you are still interested in this topic, but since no one has answered your question, I'll be happy to explain. Basically, since I2C is 2 wires, one of them being clock (SCL), and the other one being data (SDA), it inherently is unable to send data at as fast speeds as if it was going through multiple wires. I2C can send 3.4Mbits of data per second, which sounds fast, but think about 800x480 pixels, and their 16-bit colour data. That's 384K pixels, and 65536 colours for each pixel. I2C can't run as fast because of wire capacitance, which basically holds the electrical charges for a bit, messing up sync, and maybe even ruining the signals all together. To run I2C as fast as parallel, you would essentially need copper traces infinitely thin, that, or significantly out of manufacturing tolerances (probably less than 2 mil). This would actually end up being even more costly than parallel 8-bit, since ESP32-S3, ESP32 already have it. Yes, parallel interface does take up many wires, but it can reach much faster speeds because of it. An analogy is like: think of one man carrying heavy weights from one place to another, one at a time. Now, get about 15 of his friends to help him out, so that they are all doing it at the same time, and you can imagine how much incredibly faster this is. You can imagine the one man by himself being I2C (since it only has one data wire), and the 16 men being parallel interface. Although it is unfortunate how many wires parallel takes up, it is about the best we have got (at least that I have seen) at this stage. Once you get past like 480x320 pixel (normally using QSPI or really really fast SPI [like 80 - 125MHz]), everything just uses parallel interface.

I don't know..

@@ELECTRONOOBS seems like it only support ili9xxx and nextion display so i can only use the small ones

Yes! Check the Setup.h file and change the pins for an ESP8266

@@ELECTRONOOBS thankyou
