Clock it as slow as possible. Simple data logging shouldn't require a high clock.

Nice pics - indeed that seems clean. Not shown:: Anything Fishy here and here?: Just beyond 1.4" on the T_4.1 are 3.3V and GND on opposite sides. Another GND and 3.3V are side by side on the cross pins behind the SD card socket

@wwatson - Thanks for the detailed breakdown and history of this project. It is and will be a great help for our team at SparkFun! While we can't be sure of all the details in the final product, starting with something that is working and can...

Small update.. The bargraph display and Voices LED are functional. The bargraph display on the screen shows the envelope contour of each individual voice. The LED display is coupled to the NoteOn and NoteOff signals and indicates the current...

The BT pins were never routed but that an easy task for Sparkfun to do on their design. From what we saw the 1DX and 1YN are identical at least for the WiFi pins. I made the chips with both of them and they seem to work the same. It's truly...

Yes. Both above links resolve as they should now - both Edge and Brave Caching images no problem. Hit blogposts - leave and return and the images are already loaded

I edited the server config again. Hopefully redirects are working now? The redirect is always supposed to add "www" if missing, and always redirect to SSL secure. Another possible problem may be something wrong affecting browser caching of...

this. Certificate is fine, just doesn't get there going with http - p#11 link is bare "pjrc.com" and browser(s) appends http to failure. Same when using http://pjrc.com Links confirmed as noted Win 11 EDGE - same with BRAVE browser per p#11

@gigapod - Glad to see your interest in this project. A little background information and the state of the project at this moment. The WIFI card we used for testing was setup for WIFI only W/O Bluetooth being broken out. That may have changed...

HI All - First - this is a awesome project with great results. Not the easiest hardware/software problems to solve! We were contacted recently by @Dogbone06 about this project and if SparkFun would be interested. Our answer is absolutely...

Enter just pjrc.com in EDGE or BRAVE and When not specified https the site presents unsecured http not rolling over to HTTPS

We're waiting on the server hosting company to replace the server's hard drive. Time frame is unknown. Also unknown whether they will copy the old data or give us a basically a clean slate which requires reinstalling everything from backup...

I am being the messenger here as the user doesn't spend much time on the forum. It appears that the changes fixed some units that previously demonstrated the issue, but on others it allowed them to get further along in the process but then still...

PJRC.com working now in WA

And from @KenHahn shown is: Though the last units shipped here with PCB's were bottom pins on T_4.1 Indeed either can work

Here the latest version of the code running on LEDs. At minute 19:58 the diffusor is removed. And this is a simulation of a 128x128 matrix:

I think that is overstating the issue a bit. If you run the die temp all the way up to 95C which is blistering hot and the point at which the CPU will go into thermal shutdown, then the expected life is derated to 3.2 years @600MHz which is...

I was testing an FTP driver for the TEENSY41 with QNEthernet_WIFI I was getting intermittent crash reports for a null pointer. I add code to the SDIO driver "cyw43_T4_SDIO.cpp" at about line# 372. An update...

Hey, that the same page I pulled the same Quote from in p#2. https://www.nxp.com/docs/en/nxp/data-sheets/IMXRT1060CEC.pdf

Found this in NXP PDF: The i.MX RT chip is a Cortex-M7 based chip that operates at speed up to 600 MHz to provide high CPU performance and best real-time response. From first PJRC Beta of the 1062 the default speed has been 600 MHz IIRC. And...

All my Decept (hardware crypto library for Teensy 4) and QNEthernet library tests pass with this 1.61-beta1.

Why not use an optocoupler?

@defragster and @Paul, thank you for the info...

Today I explored a more artistic way of visualizing the solver data. Since the velocity field is already being calculated internally anyway, I reused it as a brightness mask for the final render output. Add a bit of saturation and brightness...

I'm enjoying them.

@shawn - I could not get the SNTPClient sketch to work on either WIFI or native Ethernet. If I change: udp.send(Ethernet.gatewayIP(), kNTPPort, buf, 48)) to: const char timeServer[] = "time.nist.gov"; udp.send(timeServer, kNTPPort, buf, 48) It...

@wwatson you've inspired me to add a note to the SNTPClient example with alternative hosts.

As a quick test, I uploaded an empty program to Teensy 4.0. Here's the results. version 1.60: empty program at 528 MHz = 85mA version 1.61: empty program at 528 MHz = 91mA

Not if you are finding it to work without any unexpected behavior. It might be chip variation or with specific code and hardware cases. Recent failures were observed on some half of a few T_4.1's running a specific complex code on a specific PCB...

Also on my mind is multi-interface support, but that's later. (No promises and no target dates.)

One other thing I forgot to mention is that cyw43_scan.ino has issues still. It will perform one or maybe two scans perfectly but will intermittently fail after that. I am looking into it. It has something to do with not resetting after each...

Just saw that secrets.h is manually included in sketch - so local copy could replace that. NOTE: FAIL :: "\libraries\QNEthernet_WIFI\examples\cyw43_scan\cyw43_scan.ino" Setup/begin Code of scan not the same as in ping? Code starts and seems...

There's some stuff I need to refactor, design-wise, so that Wi-Fi fits in better. I intend to start with a new "WiFi" class (or similar) for Wi-Fi-only things. I'm currently in the process of working on converting everything to C++ plus...

@defragster - Sorry about that. That info is in the previous library. I will add it to the QNEthernet_WIFI library ReadMe. For now this is the pinout: ## PINOUT: TEENSY 4.1 WIFI Board - 23 --------> clk - 22 --------> cmd - 17 --------> D2 -...

Opps - this is valid correction! Proper link: https://www.pjrc.com/teensy/td_161-beta1/TeensyduinoInstall.exe (@BriComp 2nd link right text but wrong link) Repeated p#2 step with same result! Except > Download came with prior version issue...

Okay - kudos to @shawn for that on QNEthernet then - that explains not seeing any hardware connect or details specific to 1DX :) Yes, See link in p#96 that hardware is here and was used for early testing Mar 19, 2026. Hoping the pins/names...

@defragster - The ReadMe is @shawns ReadMe. I just added info at the top on how to use the WIFI portion and the warnings. He did all the work on the ReadMe

Very cool @wwatson and @Dogbone06 !!! The ReadMe alone looks like an LARGE amount of work! Indeed, hardware in short supply. @PaulStoffregen collected a series of commercial variants, not sure where that is in the queue, Connections documented...

Months of work you mention, that is amazing. I am so happy to see that this now works, I need to order WiFi chips, I sent all off to you guys. But I still have 1DX and 1YN in stock so I'll order in a few PCB's so I can test this out myself...

Well, with the help of @shawn I have an initial working version of QNEthernet for the CYW4343x:) I only have the 1DX version of the chip to test with so it will be interesting to see if the 1YN? version works as well. I found the the QNEthernet...

Over the weekend I build some basic obstacle handling + improved the color mapping.

I don't think you can attach two interrupts to the same pin. Probably last one wins. You might register one per pin, with the mode: CHANGE and then detect which edge it is. Edit: option 2 - Register the first one you expect, lets say RISING...

Code seems right and the Voltage numbers it gives at change are: ---- Teensy 1062 chip ---- f/1M=16 v=950 f/1M=32 v=975 f/1M=64 v=1000 f/1M=96 v=1025 f/1M=128 v=1050 f/1M=160 v=1075 f/1M=192 v=1100 f/1M=224 v=1125 f/1M=244 v=1150 f/1M=492 v=1175...

Audio and Graphics Test By distributing the audio and graphics functions across two Teensy MCUs, the graphics on the touchscreen are fast enough and run smoothly. The red LED (left) indicates data transmission from the GUI MCU to the audio MCU...

Even the Bottom pins? The small end pads look to have SPI2 34-37 And the D+ and D- give USB_Host. Though T_4.1 as Host could treat T_4.0 as a device and give USB Serial connect for best speed, just lose easy connect to the PC to program without...

Before you upload to Teensy, try setting Tools > CPU Speed to 24 MHz. Looking quickly at the library code, the send() function at line 62 and the latch() function at line 115 appear to be written for Arduino Uno at 16 MHz. There's no delay in...
