Favorite driver for ili9488?

Found these nifty 340x480 TFT capacitive touch displays by DFRobot. I'd like to hook them to my Teesnys. (Test on 3.2 the move up to 4.0) What I'm looking for is people's favorite driver for this chipset. I'm not having a lot of luck in my usual search locations.

Thanks!

Oh, that's a littlle different.

How was the learing curve on that "smart controller" thing? I've built up this entire graphic engine for doing displays. I wonder how it would integrate with mine? My interface looks pretty close to Adafruit's GFX. I always have to make allowances for redraw time and "no this won't work like that, it's too slow." Also, none of the screens I've seen are sunlight viewable. I do a bunch of different projects. But right now? I'm in the middle of setting up a NMEA2000 system for a Sailboat. Course over ground, what's the engine doing? Are we there yet? I'd kinda' kill for a fast, sunlight viewable, display.
 
I run the display at 10Hz using the EVE libraries. I use the display to monitor the engine and collect data in an experimental aircraft. Plenty fast and smooth performance!
I bit of a learning curve for an "at best a hack" programmer like me. Someone who knows what their doing - hours, not weeks.
See the second page, 4th post here for what I'm working: https://forum.pjrc.com/index.php?threads/queued-engine-monitor-teensy-4-1-3-6.72426/page-2
 
You can get an SSD1963 7” display and run it over 8/16 bit parallel bus and get a 30hz+ refresh rate with an optimized app

Plugging ILI9488_t3 into the library manager of the IDE gives Adafruit GFX as a result. So, I assume it's not been released for the general public. I'm finding a pile of these ILI9488_t3 repositories. Who's is the.. Err, least experimental? Of the lot that I should try to see if this thing works?

Thanks!

I had no idea there was one packaged with it. I'll have to have a look. Wait, where would I look? If not in my library folder.

I'll do a fresh install and see what I find.
 
Do a VERBOSE build in the IDE and you'll see notes as to any library found or used.

If there is one in 'sketchbook'\libraries it will defer to that one, but list others found that will include the one that came with TeensyDuino install

like this one from TEENSY folder - one from sketchbook "TCode"
Code: 
Using library Wire at version 1.0 in folder: T:\T_Drive\arduino-1.8.19\hardware\teensy\avr\libraries\Wire
Using library Adafruit_GFX_Library at version 1.12.1 in folder: T:\T_Drive\tCode\libraries\Adafruit_GFX_Library

Click to expand...

In Arduino IDE, first make sure Teensy is selected either in Tools > Board or the drop-down list of detected hardware. Arduino IDE updates its menus based on the selected board.

Then just click File > Examples > ILI9488_t3. Many libraries are installed automatically, so you'll probably need to scroll down. Look for it in the "Examples for Teensy 4.0" section.
 
Ok, found that, thank you!

I'm dealing with 3 new items at once. T3.2 ->T4.0, New TFT driver chip, new Protoboard originally designed for my T3.2. So, to cut down on the variables, I have my second to last in the world T3.2 soldered to this hardware. This is so I can get this new display working. Should this ILI9488_t3 library run on the T3.2? Or is it just for the 4.x Teensys?
 
ILI9488_t3 library Is this the version of library that comes with the Teensy? I would like to clone the "real" one so I can track through the code accurately when debugging. That, and not end up on a dead end with one that's not tracking development.
