Cute. Though I'm having trouble thinking that a soldering iron would be made where the tip can't stand the temps. produced. But you never know these days. :)
Thanks. Yes, I don't have solder paste or a heat gun that isn't that directional. I'll maybe play with it, but as I said, I did recently pick up some more Teensy LC's. Fortunately, you can still get Teensy LC's (at...
Update: I think it is safe to say this is a user/hardware issue not a software/firmware issue.
I replaced the I2C cables and rewired with untwisted cables between the I2C shields and it is communicating strongly now...
Thank you for the swift merge.
Now we can go out and twist all threads bitching about no hires audio. According to to Paul, it's the #1 request of his won't-do-list, see the first paragraph of...
Hi,
I am looking for some product suggestions. I have a LED strip install in my entertainment room and am in the middle of an upgrade. Former install was LPD8806 with a Arduino Mega with an audio spectrum analyzer....

Sorry for a delayed reply. Down 4 people at work so not having to much time to play. I have however had moments to integrate WiFiNINA to FTP_Server_Teensy41. It works fine if not transferring files. From what I am...
Yeah, mechanicals. Currectly using 19mm grid to keep the whole thing compact and portable, no knobs.
End use case is cutting loose on a Synth so with that spacing is easy to nudge a neighbor and mess with the flow....
@beermat, very impressive. Umm, that's amazing. I'd say a parallel interface must make a huge difference. This SPI ili9341 is kind of a slow poke and it doesn't have all that many pixels to push.
What I'd like...
Sorry, no idea...
However not sure might help to know what does not work? Does not compile, does not???
That is I am not sure any reason why if ILI9341_t3 works with SPI and NativeEthernet why _t3n would not. ...
The Cache write stuff looks ok: I am doing an output each time we do a write to Cache:

So wrote cache 3 which was also block three to file
Then: cache write: 2 5 3 10240

As a second test I ran Tim's MakeFiles sketch using MTPDisk, MTP.begin and index file on sd card.
Copied Primes folder to SDCard. Didn't see any $$Fail messages but did see several messages like the following:

I am sort of confused here..
You show the old style of the error messages: $$$ Failed to read Index record: 8 bytes Read: 0
The code that shows read failure:

@KurtE - @defragster used my MTP_TEST_INTEGRITY sketch with the following configuration

Next steps:
Using SD with 1Primes folder and 't' I did 'b':
About 2+ minutes to copy, said it would take much longer, so I looked away and missed completion time. Src SD to PC copy under 30 seconds.

Kurt, using that and your sample with no LFS_Prog.

Quick update: You might try this storage.cpp and see if it resolves the issues.
It appeared to work for my copy of all of those files with just the one Storage on SD...

If the tab completely covers the pad, you have to either use a heat gun or maybe have your iron on the tab for some extended amount of time to try to melt the solder under the tab. I might add a bit of solder paste to...
My problem is with the USB header on place, there is no way to touch the tabs with the iron since the usb header is sitting on top of it. With PSrams and such, I can still see the top of the chip's feet and touch the...
Just tried it with the usb drive and partition files transferred no problems will try again with the SD Card
UPDATE: Just tried primes with sd card and had no issues
I tend to always startup serial first then MTP.begin - just habit. For sake of transparency I only tested with your makefiles2204 - didn't try the primes test. Just ran another series of tests as well using the...
Did you find any info concerning this?
…having what I belevi the same problem with a Novation LaunchKey 25 that has two ”ports”, but I can only reach the first?
That built and ran. I see it uses MTP.begin().

I can use NativeEthernet together with the original ILI9341_t3 library, this works well using SPI, not SPI1.
But now I want to migrate my display to SPI1, because I need SPI for the HighPowerStepperDriver lib from...
Quick note: I am having File writes and reads fail... And maybe more related index_seek(block_addr, ...) is failing
The current SDFat may not be allowing seek to go beyond the current size of the file.

Hi Paul
I have a Teensy 4.1, is it possible to open two .txt files both in write mode at the same time? like can I do
File dataFile_1 = SD.open("temperature.txt", FILE_WRITE);

Ahhh, gotcha. Yes, there is no "quick start" for a combination of a "bare metal" device like the Teensy and a graphics library such as LVGL, which is capable of running on multiple platforms. The documentation should be...
@defragster - @KurtE
Here is the integrity sketch with only 2 drives set up (Builtin sd card and Program Mem). It seems to work for MTP+DISK with Index in Progam Mem - you might what to give it a try.

I just took a look at my LC. The microUSB has two surface tabs that can be soldered by hand. First you want to check the solder pads (2 for the tabs and 5 for the connection) on the board to make sure they are all...
Probably not. All MTP.begin is doing is starting the interval timer handling the first few messages to quote Kurt. Why it works not with MTP Commented out with MTP_Serial not sure. More investigation is needed
Thanks Kurt, built that sample and it ran until it hit the 'pool' ERROR, will need to add the LFS_PROG.
Enabled the debug in MTP.cpp

This code works fine when sending midi between two separate MIDI devices connected with a USB Hub to the USB host. Any...
Cool. Thanks!
Looks like exactly the thing I am looking for.
Although. like I said before. I don't mind adding more expansion chips, or even more teensy's.
As presently its a private project, so the costs don't...

Hey MatrixRat
thanks for your help. Sure. I am in the process of learning and trying things out, with a working version of Steinberg Pro 12
So will see how the performance pans out.
I do have a handful of...
Noted compiling with MTP_Experimental, have made no edits to CORES - including the USB Descriptors
Indeed the 1_Primes issue cleared up with LFSProg for MTP.addFS(), but the bad xfer of 500 Byte base files still...
I was thinking of a simple shift register, but then I thought why bother with external parts, when a Teensy can directly read out the matrix even faster.
A quick calculation gives the following formulas for the...

Hi All,
I found a way to reset the counter, but it's kind of dirty...
In the iMXRT1060 document, it says that if you set GPT1_OCR1 to a new value, it will reset GPT1_CNT.
So within my ISR, I just set GPT1_OCR1...
Why not use something like this?
It will be off by a few us every stroke, but since you are only going at 500 strokes/s I don't suppose it will matter.
The purists will say that this is NOT the way to do it, but I...
Hi All,
Does anyone know how to reset the General Purpose Timer Counter registers? For example, within an interrupt, I want to read the value of GPT1_CNT, and then reset GPT1_CNT to zero. This is def possible with...
I have recently finished a Driver for the Nextion Display.
Actually it is a Skeletal driver with most things done but an area where
you can insert your own code.
I have also developed a Text Monitor page on the...
But isn't the battle with LVGL getting the initial setup installed, configured, working and tied in to your display driver to output to your screen? If you got to the point of displaying a text button, then surely you...
usb power voltage 5v indeed, by burned out i mean stopped working( even simple blink code), and yes we are feeding it to encoders to read their data, and they are fed 3.3 . the thing is that when i tried reading from...
@defragster - quick question are you running your Makefile sketch as MTP Disk or MTP Serial?
One reason I ask is some places in the code you have:
#if defined(USB_MTPDISK) || defined(USB_MTPDISK_SERIAL)
#include...
How did you get that to work? I spent some time with it, but didn't get very far. Do you have any notes that you could share on getting it up and running? LOL it took me a day and a half to get an arbitrary text...

Thank you for your fast answer. In order to understand your idea, I checked in SGTL5000’s (codec used for TEENSY AUDIO rev D and driven by TEENSY 4.0 ) datasheet (https://www.nxp.com/docs/en/data-sheet/SGTL5000.pdf) the...
How about using a Nextion?
You design your screen offline on an editor. Then send it to the Nextion display.
The display just sits there until you send data to it.
Basically it's a display with it's own...
Easiest way is to use I2S2 for the mic.
https://www.pjrc.com/teensy/gui/?info=AudioInputI2S2
Then just connect its 3 wires to pins 4, 5, 3 which aren't used at all by the audio shield.
High Paul,
My intention is to use a I2S MEMS microphone as input and to hear the audio captured signal in headphones using the output of AUDIO SHIELD ( to benefit also of SGTL5000 output capabilities). As I understood...
