NT35510_t4x_p - a parallel display driver for Teensy 4.x boards

NXP might have used the NT35510 is one or some of its development boards, but I don’t recall specific application notes to interface with one.

There is a FlexIO app note for the K series that uses an HX3857 for example, but the focus is less on the lcd config and more on the NXP config
 
In fact I want to use some old phones lcd (as far as I know based on NT35510, and from readed manufacture id: 55 bc c0 seems so) but without positive result.
Capturing data with logic analyzer I see that phone at startup initialize lcd but in DCS Command mode only and I need in video mode. I try to set bit 4 in DOPCTR but also no result. All I get is an image with noisy pixels, like an old TV with no signal (or snow may be called on some context) but instead black-white is color pixels. (hope you understand my example)
Datasheet is a little scarcity in information
Forget to mention that working mode is MIPI-DSI.
Also is not for NXP but for RPi instead.

That .8 version that @BriComp linked to, is about the most complete version I have seen. has more information than the version up on BuyDisplay.com.

My guess is that you may not find anything more complete, except maybe by contacting Novatek and they might have additional documents, that they may require you to sign some NDA... Otherwise, the only way I have had any success is through trial and error, plus looking around for other
display drivers for the display...

Good luck

Some of these displays support multiple interfaces; SPI, MIPI DBI (8080/6800), RGB dot clock, MIPI DSI.

The Teensy 4.1 and Teensy Micromod can drive these displays in 8080 mode ocer 8 or 16 bit bus. Or over 8 bit RGB.

MIPI DSI is not supported by the Teensy

How are you driving your display? Confirm wiring and lib config.

The colored snow you are seeing is probably the random values in the display’s internal GRAM
 
I realize what you need, I forgot they named the support documentation this way, too. This document helped when I was figuring out some stuff for the NT35510 a few years ago....I'll PM you a link to the NT35510 Application Notes PDF I have, v0.07. I haven't seen this file distributed much online either, just the datasheet.
