Was wondering if people are aware of this activity: TeamPCP hacking GitHub Scares the heck out of me. Seems that lately a lot of big sites are having issues. They specifically mention PyPi repositories. Teensy sure has a lot of exposure to GitHub. Hope it's being watched? checked? or...

By the way, the initial compilation seems to compile much faster, almost faster than previous version re-compiles. Guess this has something to do with the also observed no 'Intel' in Activity Monitor when running Arduino.

macOS26.5.1,Arduino 2.3.10, with large program with a bunch of libraries in my documents/Arduino/Library FYI Got lazy and didn't follow my personal procedure for major updates. Every thing compiled without errors or warnings awesome! However buttons that used gpio_expander didn't respond...

Just curious about what's involved with having a library distributed. I'm sure there's a document but I can't find it.

From the start of a typical compile: Detecting libraries used... /Users/xx/Library/Arduino15/packages/teensy/tools/teensy-compile/11.3.1/arm/bin/arm-none-eabi-g++ -E -CC -x c++ -w -g -Wall .....

Arduino lists as 'macOS Apple silicon' which is ARM

Yes, it runs great on Apple silicon with Arduino 2.3.8. Thanks for all the work Paul !

MacBook Air, Tahoe 26.2, IDE 2.3.7 working great. FYI Arduino finally made the terminal window properly cut and paste the whole session without skipping anything. (Only took 2-3 years to fix?)

Working fine for me still although I haven't added any of your new stuff yet. Oh come to think of it, Aduino 2.3.7 with Paul's beta6 didn't notify me to update, I saw email of this thread.

Sorry for taking so long to get back. I have a 121GW multimeter from EEVBlog. It's an awesome meter and a little pricey. For the specific task you are looking at this video does a good job of explaining the issues. The 121GW does the same trick as the uCurrent gold in the video as its design...

I can log the USB power with 10uA resolution with 5 measurements per second, but with no triggering or precise timing. Also could try with an oscilloscope and current probe with less resolution but timing.

Would this be measuring the USB current or something on the ethernet wires?

That is an amazing project, and I thought that I was THE NURD. The software, hardware, 3d printing and maybe some electrical design by one person are inspiring. You even made it fun for your kids, which I could never do. You have inspired me to submit my automatic bicycle shifter I have been...

the second while: while(x>0 && z>0){ should have been (or was originally) : while(x>y && z>0){ but demonstrates that even a test of positiveness fails.

Problem with optimization settings when testing around max integer. Arduino IDE 2.3.6, T1.6b5. This worked back in 2015 :) void setup() { int x,y,z; Serial.begin(9600); while (!Serial) ; x=2; y=0; while(x>y){ y=x; //keep the last value x*=2; }...

I'm guessing this is a bad solder joint on the large bga (Ball Grid Array) package. The crystal is connected to the worst possible location on the package bga stress wise. see: https://forum.pjrc.com/index.php?threads/teensy-3-6-program-loader-and-i-o-glitches.40638/...

I guess reverse polarity protection with a .04 ohm on resistance instead of the .7V drop of a diode.

Installed on MacBook Air, Sequoia 15.6, Arduino IDE 2.3.6, no problems. Not sure if instructions 4 and 5 are mixed up. Seems you'd need to install b4 indexing? That's what I did. With the restart it doesn't matter anyway. Only looked at a T3.2 program, 48mhz, faster, i2c_t3, SPI...

try tft.print(c); instead of tft.drawFontChar(c);

Wonder is Sparkfun might restart T3.2

You asked for it :) 1. The KiCad is a few versions out of date, which wouldn't matter except the libraries are significantly different and parts from your custom library are missing. Starting around version 6, (9 is current) there is an 'Archive Project' button that will zip all the symbols...

Interesting project but I have issues, the main one being issues is turned off in Github so I can't add constructive criticism.

? As noted in the original post the data sheet says .02mA which is 20uA, not a few uA. Even if I could get 20uA that would be 90 instead of 50 days, still useless for my application.

Just reporting noticed today that issue at #27 seems to have resolved itself with no input from me except possibly upgrading to Sonoma 14.7.1 I'll be updating to Sequoia 15.1 soon and will report.

On M2 Macbook Air with Sonoma 14.6.1 and IDE 2.3.3 Tried all the shenanigans in earlier in post for win and mac but still get no security stuff: Read security was not recommend from M2 mac but it should be possible? Oh and added: Should Teensy Loader show 1.60-beta3 vs 0.60?

I can confirm that it runs correctly on 1.60 beta 3. Maybe I'll make the switch to beta tester. What could go wrong ? :)

Thanks for checking. Problem seems to occur only on Teensy 3.2 3.5 and 3.6 Not on 4.0 or 4.1

Using Arduino IDE 2.3.3 on MacOS 14.6.1 Sonoma, Teensy Loader 1.59 The code below: int gdefaultState=7; void setup() { Serial.begin(115200); while(!Serial); ; Serial.printf("in setup gdefaultState=%d \n", gdefaultState); } void loop() { static boolean finished=false; static...

I'm not familiar with that scope. Is the signal really <1V. I had an early T4.1 where that particular 3.3V pin was not hooked up. Is it 3.3V?

Will switch to GitHub.

Observed no compile. Quit, deleted the cache as above, then restarted reinstalled v29 then same. This any help?

@shawn Dang, can't understand how it's not showing up for you. I had been deleting the cores and sketches cache at /private/var/folders/q9/p*/T/arduino, YRMV, but haven't tried deleting and reinstalling the libraries.

client.close() instead of stop() caused v0.28 to also print the "Host: 192.168.1.97" but didn't effect it's speed. v0.29 seemed unaffected and the same slowness. Interesting that the Get and Host line print at nearly the same time after a long 4 to 5 second pause when each line requires a new...

The extra line (Host: 192.168.1.97) occurs when the 'real' time is > ~3.5 seconds. Sometimes it takes 3 or 4 tries to build up to >3.5 but becomes about 5 seconds. Even if I let it alone for 5 minutes the 4-5 second delay will continue. Unplugging the teensy and replugging and using just the...

Found another clue. Running blinkServer #226 at 24Mhz and then using the served page button or the time curl I get an extra line on the Arduino terminal in v0.29 that is not in my code: GET / HTTP/1.1 25 Host: 192.168.1.97 26 GET / HTTP/1.1 27 Host: 192.168.1.97 28 GET / HTTP/1.1...

Edited the current draw issue above but the speed issue at 24Mhz remains. Using the time curl test repeditively with about 1 second after a response the 'real' time increases about 1 sec each try until it levels at about 6 seconds. The same procedure with v0.28 stays below .06 seconds.

I'm running on a wireless local network on a M2 mac Air. Tried the curl at 24Mhz, Faster: v0.29: real 0m4.075s <--- user 0m0.022s sys 0m0.015s v.028: real 0m0.060s user 0m0.020s sys 0m0.014s The reason for using 24Mhz is in my app it draws 95mA vs 322mA @ 600Mhz. Don't...

Sorry, I messed up posting as I don't see it here. Had a table with some numbers. I am running the teensy at 24Mhz. At 600Mhz it seemed similar.

Thought maybe the sprintf might be the problem since the change notice said printf had error correction added but removing it from the main loop didn't help. I do occasionally get 3-4 second delays, but usually ~2. BTW I never heard from anyone at all when I posted this code before. I thought...

This code I posted a few years ago #141 puts up a web page that allows you to turn the onboard LED on and off. It is almost immediate in v0.28 and about a second in v0.29. Don't know why it's not 4-5 seconds like my other program. /* blinkServer 2023/8/22 * cleaned up version of...

Seems to effect both UDP and HTTP.

Wow, you guys really keep at it. Thanks Installed v0.29 over 28 just now using the automatic update in Arduino 2.3.2. Having an issue where replies from a teensy 4.1 server are taking 4-5 seconds for some reason. Went back to v0.28 and all is well again with replies seemingly instantaneous.

Sorry, I forgot to mention it happens regardless of using subfolders.

The one on the right is obvious. The one on the left is my favorite for custom printed boxes. You do a boolean subtract of it from the box wall and when printing pause when you get to the top, insert it and keep printing. Both are printed face down with no supports.

IDE 2.x allows you to get away with murder but you will eventually get caught if you're not carefull. I have gotten used to using python and swift where .h files are not used. If you write perfect code IDE 2.x will just piece all the .ino files together no matter if no function prototypes, or...

Seems like opening a larger can of worms. So when your done you do everything over with the real sensors?

Digikey currently has lots of chips and no obsolescence notification that they are usually good about. https://www.digikey.com/en/products/detail/nxp-usa-inc/mk20dx256vlh7/3742957 Could it be there is still a need for this chip with its many advantages over other newer, cheaper, faster chips...

That was really interesting! This USB-C head2head shows how you get what you pay for.

Thanks, pulled latest, fixed.
