Sorry, there is not enough information here, to suggest what issues you might be having with your ILI9341.
There are lots of options for displays. I will only mention a few of them, as ones that I have played with and libraries that I have...
Right not I am contemplating if the 32 bit frame buffer is the right way to go for 24 bit color, or if I would be better off with packing it to 24 bits per pixel... Probably would make it easier to support DMA and IRQ support.
For example, when...
I always backup the USB connector when plugging in the USB cable. By that I mean, laying the board on a flat surface and placing a finger on the backside of the female connector on the board then plugging in the cable with the other hand making...
What you are doing, with an improbably high word count, is rejecting any suggestion that doesn't fit the answer you have chosen.
I have never had an issue with a loose usb socket. Only one tearing right off.
One.
A suggestion in general ...
Sorry for the delay in responding. Rather out of it. Wife and I are both pretty sick with some bug. So checking forum only periodically now.
I agree with @KurtE. When the default remains at 88Mhz there needs to be some way the user to change...
Or you can use my variants version of core and try to create a variant for yours...
I took the simple way out to start with, which was I did not collapse the pin numbers, for ones that were not available. Their current 4, 4.5 and 5 boards are...
Hey folks, I'm happy to report I was able to create a custom teensy with sdram using this thread as a reference 😁
I was already in the throws of designing a custom teensy board that had usb host, usb device, and microsd all on a single edge...
Often times when I am playing around with a Teensy 4.1 that has PSRAM and I wish to use it, I find that the default 88mhz speed is too slow.
I am playing around right now with a T4.1 with an NT35510 display on it that is setup using a 16 data...
@DJETH - Just as a heads up, I wired up a T41 to a ER-TFTM101-1 for testing purposes and ran through all of the examples. I have found and fixed some bugs in the driver code for 8080 mode. I also made several changes and updates to the examples...
I have a small issue with rendering an image to the RA8876 using the DB5, DMA, 16-Bit mode and 20MHz or more. Here is the image:
The picture is torn. Now if I copy the image to SDRAM the image turns out like this:
Could it be that the access...
In our application with the T4.1 those resistors are not needed or used. I did try connecting them and it did not make any difference in operation. Possibly they were needed for use with the STC12LE5A60S2 MCU...
If you download this interfacing guide and look in the lower left corner of each section it lists which jumpers to open or close for each type of interface...
There are a few threads on this forum that are related to the ER-TFTM101-1 10.1" display as stated above by @thebigg. The most recent of them is here. Me and a few of the other members have been working on my RA8876 driver for the T4.1 and...

There is lots of work currently underway on this forum on the RA8876 driver
Sorry, I know,mostly talking to myself 😀
i now have the 16 bit bus display, connected to T41, it is on left, the BuyDisplay one on right (8 bit),
color band 565 vs 888 on both running 24 bit
running my clip… test 16 bit color shows still some...
Sort of place holder to be edited...
Decided that probably should split this off from the the thread:
Will probably do likewise for HX8357 and not should if we should for ILI948x as well?
The current WIP code is up at...
Currently I am experimenting with 24 bit color as well as using either 8 bit or 16 bit buss_width.
The current code has so far only been tested on some BuyDisplay displays that were configured for 8 bit bus:
I believe it is this one...
@KurtE @mjs513 - Finally getting somewhere with 8-Bit bus and 24-Bpp but still not quite there yet. This is with Async and 8-Bit bus.
Using the existing pushPixels16bitAsync() function (un-commented part):
FASTRUN void...
Yes just playing around.
Quick update: PNGDec appears to be happier when I use the Github version versus the version downloaded by the library manager. :D
I will wait until your next drop of stuff, before doing much more with the sketch and playing.
I found some standoffs and actually some screws that fit them…
makes the area look a lot more organized 😆
@KurtE - I'm sure there are a lot more issues with the 24-Bit library to work out. I am still fighting to get 8-Bit 8080 bus to work with 24-Bit color. It's probably something simple that I have not detected yet :) Will keep plugging away at it...
Nice, I updated it to play with some additional things, like the ability to try to turn on useCanvas. (c command)
it is not working too well yet. Also within canvas I also tried to update using async... Got worse.
Funny, I have much better...
PNG file works:
But jpeg file seems to missing red colors:
Otherwise it works without having to convert pictures :D Nice...
Edit: Tested with some other jpg files. Some were good and some were not...
But not completely
Turned off using buffer and the fill screen worked to red,but write reacts are screwing up. Was running for awhile and all appeared to be fine
Edit: Updated sketch
I have a version now that runs. Note it is held together with bailing wire and spit :D
But included it here if you want to try it.
It can be run with MTP enabled or not. Currently I have it working with image files on SD Card (bmp, jpeg and...
@mjs513 - was curious to try your raytrace sketch you posted on one of the other threads:
https://forum.pjrc.com/index.php?threads/ra8876-parallel-display-library-testing.75345/page-13#post-347610
And wondered if it would improve to have it...
Results are looking great on the NT35510
Can’t wait to test the 16 bit bus version once you get your other display in @KurtE !
I might just take the 8 bit version and modify to run on a 16 bit bus/2bpp to see what I can make of it if I can find...
@KurtE @mjs513 - Finally got back to the 24-Bit color libraries. So far I have the all but TeensyRA8876_SPI converted. With that said, here is the two 24-bit libraries:
https://github.com/wwatson4506/TeensyRA8876-24-Bit-8080
and...
Not yet. Still finishing up. I made some more changes and DMA quit working :( SPI version is going to be really interesting. As it turns out All three libraries have to be changed so that is going to mean three more repo's. Today I will upload...
I've uploaded an annotated copy of the NXP Reference Manual. It's linked from the Teensy 4.0 and Teensy 4.1 pages under Technical Information (where the plain old manual was). Here's a direct link to the PDF...
@KurtE - Finally have the shield soldered up except for the three 14 pin single inline female connectors. Still waiting for them (Aug 15th). Took me a while but it's working. Had lot's of soldapult usage :D It's nice to be able to have just one...
Well, Since the HX8357 also supports 24 bit mode, although unclear if internally it supports 24 bits or only 18...
The HX8357... library was updated with the same stuff
I should probably split the NT... off to different topic...
But was playing yesterday with Image viewer sketch to output images in 24 bits. As I mentioned in the prevous posts, JPEGDEC has added
ability to output in RGB8888 format, which the...
Note: my EBay order says it should arrive: in about 10-17 days from now...
Yesterday was playing some with some 24 bit support. In that if the dataWidth is 24 in some cases it now converts 565 to 888 and outputs.
Not perfect, but do have some...
Thanks for the heads up. Maybe we should use your config file as the standard config to work off of. It's more inline with the shield and other variations. What do you think?
