The gumstick-sized Teensy 4.0 made this project possible! Fender's iconic Stratocaster's control cavity was routed to accommodate a few analog pots and a dual-pole 5-position blade switch but I've crammed the Teensy, a stereo codec, two RGB LED...
Hopefully it is CERT trust that will build with more exposure as it is NEW - even though PJRC NAME is common from prior.
Still needed Double Keep - with EXE name change it will still be inclined to show this as 'not commonly downloaded':
Until...
Does right click properties show it as BLOCKED - - not seen that here but downloads can get marked that way too and require flipping that switch to allow it to run.
Did a quick scan of https://www.pjrc.com/store/teensy41.html and not seeing any notes on previously discovered behavior of pins #24 and #25 during Upload where they are driven high in some fashion. Seems that and added note when using a locked...
Pin #24 and #25 during programming receive some level of 3.3V - enough to light an LED DIM or Bright. Not seen on other edge pins.
That has been noted if not documented and needs to be considered in use of those pins.
AFAIK: This is the first...
Considered adding verbose - but easy to repro ...
No GND<>25 - all is well locked T_4.1

Just did a quick test regarding pins 24 and 25 on Locked T_4.1 that are pulled high a little (25) or more fully (24) - lighting an LED on those pins.
If Pin #25 is tied to GND the Locked T_4.1 cannot be programmed. The RED LED never lights and...

But I think there is a bug in it:

Hello Defragster
As I am not Defragster
😉
Find the TyCommand (formerly TYQT) thread and install and use TyCommander.
It recognizes multiple Teensys when connected and allows connecting to any DUAL or TRIPLE port they may present.
See...
That worked - just had to find and select "KEEP" two times.

It was not deleted, and a manual scan with Defender did not find any issue.
And that was before manually checking for this...
@PaulStoffregen : Wondering if you made another test EXE - now that your NEW CERT has been tested and approved once - if it might be better accepted?
It would only work with the most recent Update to the Windows Defender Smartscreen 'database' -...
Midbar (Teensy 4.1 Version) V3.1 is released.
This version of Midbar can encrypt data that can be decrypted in the desktop app and vice versa.

Next level (or lower?) tip: In IDE 1 or 2 [command may be different in other IDE] do:
Ctrl + T : 'Auto Format'
Copy & Pasting code after that assures some uniform formatting and indenting.
This Ctrl+T is also handy when unclear/Random Build...
Have not seen download problems with 'false positives' in recent memory. And last TD updates have had no issue with any EXE changes for IDE 1 or IDE 2.
Tried download again and failed - the 'RULES" hadn't been updated for Virus.

Turning this off allowed keeping download and running it:
<edit>
MalwareBytes scanned and found no issue.
But enabling the above had the EXE deleted as a virus.
Got these notes downloading and trying to keep it ... then reported as SAFE ... then it was determined to be 'Virus detected'

This seems oddly unique among the posts and history AFAIK ...
Really Odd
And this is really ODD as the two ways to get BLINK on a T_4.1 are #1:Manual Upload and #2: 15sec Restore only by holding the Program Button on a powered Teensy ~13-17...
The MicroMod is working with the ER-TFTM101-1 display.
Still have to get the DMA portion working on the MicroMod. The images were produced in 8-bit mode none DMA, 100ms to display both pictures. I'm sure DMA will speed things up. By the time...
Somewhere in history back @mjs513 posted these images of the bare DevBoard I got and scanned associated with the pin names. These are in the DOCS folder of the original github by @defragster that got abandoned when the lib was forked ... not sure...

I vaguely remember some space related posts. I did a google search, but I didn't remember most of these. I suspect they don't meet the criteria of space qualified (but with it in several amateur rockets, maybe it is near space)...
I just released v0.27.0. Here's the Changelog:
## [0.27.0]
### Added
* New `QNETHERNET_FLUSH_AFTER_WRITE` configuration macro for flushing after
every call to `EthernetClient::write()`. This may reduce TCP efficiency.
* Added a W5500 driver...
@manny90:
Without seeing the contents of your sketch, any guesses would be just that: pure guesses. Posting your sketch would at least allow others to take a look, & maybe then, some potential causes might be noticed. Posting your sketch would...
@Rezo - I wired up the T41 for 16bit I/O and did some basic reads and writes. All failed. I hooked up my LA to monitor the first two bits of the high byte and low byte. Was reading 0xff from the status reg which was wrong. It should read 0x50...
If there is a newer one ... not sure I've seen it. Not even sure I saw the update with the 'CARD style' Function color labels on before - nice improvement.
Yes, exactly, a massive difference in raw speed.
In addition to all the points Defragster made, when memory mapped you also gain the (usually) huge benefit of M7's cache.
Good posting - Handy Sketch! I went looking and got distracted ... Used it with the SDRAM DevBoard to confirm the wired and 'extra' pins not connected.
Note for things like this, I end up using sketcth that @defragster and I played with a long while ago:
It sets all of the pins into either INPUT_PULLUP or INPUT_PULLDOWN. You can then take a jumper wire from either GND or 3.3v depending on...
Standard SPI is one bit per cycle of the clock - that runs more slowly.
QSPI is QUAD or four bits per transfer and runs at a faster clock rate.
And in the case of QSPI PSRAM it is memory mapped and as such the chip transfer interface is fully...
I just placed a 1000uF decoupling cap at the 5V Teensy VIN and voilà, the tikitik is gone :)
Long time with this problem, asking is needed sometimes to get clues and organize thoughts.
Seems backwards ... perhaps the processor on the SD card is doing more work after larger writes?
Would something like https://www.sparkfun.com/products/9419 ($12 sniffer) maybe move the CARD away from the Teensy enough to change anything? At...
Well I finally ordered the Buydisplay ER-TFTM101-1 with capacitive touch and had it configured for parallel communication in 8080 mode. Using parts of @Rezo's ILI984x_t41_p library, I was able to adapt my Ra8876LiteTeensy library to use the...
My guess was the WEB refresh was overlapping during/before the same 'inline' request from the PShell request.
Putting the inlineB path in the code seemed to resolve the issue - as each of the two requesters would only send one at a time, so...

Speaking as a well-known member in the devboard conversation (or at least one of them) where defragster has included images, I see no such drag+drop option to include images, only the URL field.
Okay confirmed - as a Sr+ drag and drop works for @defragster - mistakenly thought others had dropped too - where @mjs513 and @KurtE are also Sr+ and they may have managed as well on that PM thread.
Doing the SDRAM @Dogbone06 has also been on...
Interesting - perhaps that is something unique to Sr+ - AddOn's not the same as the old forum - perhaps that is one.
@BriComp - I'll add you to PM noted above to see if different?
