Thought I saw something a while ago about this. This may explain it: https://forum.pjrc.com/threads/70660-Teensy-4-0-analogWriteFrequency-rounding-errors?p=309572&viewfull=1#post309572

Nice @KurtE - looks like you got almost 100% working :)

@tjaekel - nice job on getting it work.

As @joepasquariello and @wwatson said is its own file system. Its designed for use with NOR or NAND flash chips. On the T4.1 that could be on the QSPI bus as well as on one of the SPI busses for the T4 or T3.x chips. ...

Well you made me look and sure enough the sketch as written uses 309k. Looks like most of that is coming from using IOSTREAM. If I change the sketch to: #include <iomanip> //#include <iostream> using namespace...

@PaulStoffregen - @KurtE Based on the testing so far think this would a good idea to add for the next beta - so basically I second what @KurtE said on getting the PR's incorporated

Just ran across something interesting with the new toolchain and and updating to c17 Found that cout now works (no cin does not) and the c++ function setprecission works. Came across this when I was looking at...

Thought had crossed my mind when I was working on it. Seems that stuff that we did is always in the back of my mind when I work with the IMU's

Did a bit more work on the 2 sketches - wanted to see about requesting a data set and receiving just that data or if I wanted all of it so I created a menu on the host side: Command list I - Get IMU Data L - Get...

As a test I decided to see what would happen if I used a T4.0 as a sensor hub and then send the data via RAWHID. First I pulled out the old sensor board that we used for I2C testing using just the BNO080 and the...

You may want to check out the spislave_t4 library. Check out this thread to see if it works for you: https://forum.pjrc.com/threads/66389-SPISlave_T4?highlight=spislave_t4 As for really long cables - ditto to what...

Synched up the changes and used RawHid512 to xfer that problematic jpeg up and down. Both xfer's were successful and images displayed correctly - just from that limited test it looks like it works.

You may want to test the display without trying to use the SD card or the PCA at the same time. Think that the issue is that you need to have the MISO line attached for the SD card to work. Never tried the SD Card on...

First - not sure what display you have, what sketch you are using or what your wiring is. The ST7789 320x240 display that we tested with was from Adafruit...

@KurtE - @wwatson - @defragster Did some more testing with that one jpeg that showed issues with uploading and downloading with MTP enabled. Found that if you just comment out the mtp_loop command in the...

Glad it all worked out. And thanks for turning everything off and testing. Didn't get around to that yesterday :). Even with everything turned off most files I transferred seemed to have not issue except for a few...

Thats pretty much it. One change you need to make the host sketch void loop() { mtp_loop; myusb.Task(); uint8_t filename; int cmd = check_Serial_for_command(filename); if (cmd != CMD_NONE) { ...

Ditto - me too (playing for fun). Just wanted to let you know.

Afternoon @KurtE (at least in NY) Anyways I downloaded the latest and greatest changes you made and tried transferring a 4.8mb jpg. The sketch says it transferred the file successfully: ...

It sounds like making "ms" volatile is the safer way to go.

Don;t think I am going to be able to confirm this - I tried connecting with firefox/IE/chrome on Windows 10 and Firefox/chrome on a android phone and could not connect to the ap server. Tried with a airlift featherwing...

Can you tell me what sketch you are using to test with. If its the sketch in your previous post it does not seem to be working for me. Yet if I run some of the example sketches from WiFiNina or WifiNina-geneic they...

Cool article Mike - I've seen the overclocking video before which was fun.

@thebigg - @brtaylor Yes you are right I forgot a copy and paste of that in the examples - didn't seem to be much of impact of leaving it out though that I could tell. Last couple of days been rewicking the example...

Yep - that was what I was looking at - the little breakout board of theirs - really not worth the money to be honest. :) Thanks for the RTK link will have to check it out.

Hi Brian And yes - still like the 6050 or the 6500 (but the 9250 grew on me a bit). Not a fan of the new ICM boards for some reason. as for that ADIS IMU looks like the price just doubled (looked on digikey) :( ...

Got a bit curious about what would happen if going between versions other than what was mentioned. So here goes. Actually had to run the comparisons twice. On the first set of install downgrades/upgrades...

Cool let us know how it works out. Any suggestions for new MEMs IMU to play with :)

@brtaylor Just gave it a test spin using your old MPU-9250 library which has the calibration and FIFO functions still in it (https://github.com/mjs513/invensense-imu/tree/MPU-9250_custom) along with @DonKelly...

The example above is using the QuadEncoder Library.

Could be - just don't know enough about the risks but now that you mention it might very well - probably should just kill the PR. Could very well be. The Eigen library is all headers so it seems to work. The UBX...

@luni - @CollinK Ran into the same problem with a couple of @brtaylor libraries. Since the libs weren't mine I added ifdef/undef to the top of the sketch before those libs. Did put a PR in to Paul and reported to...

Yes sir. The ILI9488_t3 lib has been updated with the current stuff

Madgwick's fusion library caries the MIT License - check out the main branch

Been playing a bit with Fusion using NXPMotionSense lib and FreeIMU Lib. In both cases I started with calibrating using either MotionCal for NXPMotionSense or the FreeIMU Cal GUI: from MotionCAL and FreeIMU GUI ...

Files were just deleted between the main branch and the teensy/arduino branch, i.e., here is a screen shot of the main branch: and my branch MainBranch Fusion -> TeensyBranch src Examples -> Examples but added...

Morning Joe Probably bad wording but basically just restructured the lib for arduino and deleted the python folders, etc.

Hi @KurtE was just looking at colors.cpp and looks like there may be support for RGB565 transparency - not sure: /** * alpha-blend `fg_col` over this one with a given opacity in the range 0.0f (fully...

@KurtE Pretty much did the same thing as you. Ran Paul's test case, not changes, plus duplicated what you and I saw with running 2 sketches with different USB types. Like you said looks like that issue is fixed...

@PaulStoffregen Was playing around with a library and decided to test propsheild again with NXPMotionsense but noticed that its no longer in the examples list of either 2.0.05 nightly or 1.8.19 with 0.59.2 not sure...

Just did the merge so the ILI9488 lib should be in sync now with the ILI9341 library.

Nice work @KurtE. Updates to Graphics libs never stop do they.

Not automatically I don't. Only thing I can thing of is to download the commit around that date. Maybe this one dated march 7: https://github.com/arduino/arduino-ide/tree/24dc0bbc88bcfd083e03b0c8601cffb08e8d5728

If you looked carefully at the issue that @KurtE raised on github you will notice that I found the problem started after the 3/11/23 nightly build. As of the 3/11 build it was working with out a problem

Actually you are right and my fault for not remembering thanks for reminding me. I actually put in a PR to that back in September 2022 to fix the issue: https://github.com/PaulStoffregen/cores/pull/655. Guess will...

@Paul - @brtaylor I was in the process of updating a very old library that I had and all was going well until I was trying to run an example that used the eigen library from @brtaylor...

Good Morning All - hope everyone had a good day yesterday. Installed updates in 1.8.19 on a win 10x64 no issue Compile with faster Talkie Toms_diner example with any errors so old ways still work :) then tried...

Still taking my first sips of coffee so confuse easily until after second cup. :)

Ok you lost me Tim. Haven't seen a beta 2 out yet in Boards Manager for 2.0.4 or an anoucement?

You had mentioned trying a different MAC app for MTP and I think @KurtE mentioned one as well. Maybe if you have time to play around with it you can check out one of the other MTP implementations. Good luck

Haven't run into that problem - don't think but definitely good to make that change - will have to check on one of the drives I have laying around that never worked

Ok had a chance to get back to this and tried to incorporate your approach with my setup just for testing purposes. Basically logging every minute until the next hour is reach. Here is the sketch: #include <Wire.h>...

@defragster As I was working on something different I was relooking at the Talkie library. It looks like the latest incarnation of Talkie does a bit of rework to support the Teensies:...

Thats great news about Laik. Know how it feels when our little ones are not feeling well.... Paul. I do have a question on what you are showing for backward compatibiltiy: #if TEENSYDUINO >= 159 using...

@luni Wow - that was fast. Just going through it now and its great info + a great tutorial :) Note: probably wont start experimenting until beta2 comes out - just in case :)

Good question - I never checked EDIT Here is the answer: Serial plotter does not plot #1597. Looks like the changed the behaviour:

Took me a while to find the issue. The really interesting thing is if you use 1.8.19 there is no problem with the extra space, problem only exists with IDE2

Thanks Paul and that makes sense based on previous examples. Ok that makes much more sense now. That first link is great by the way. A while ago I was looking at this...

Been trying to follow along with the use cases for inplace_function, especially from a c++ novice point of view. Back on pages 1 and 2 of this thread @Paul and yourself posted several examples (post 1 basically and...

Benchmark for various C++ function implementations: https://github.com/user706/CxxFunctionBenchmark/tree/feature/sg14_inplace_function stdex::function<int(int)>: 24 std::function<int(int)>: 64...

By any chance are you planning on enabling exceptions for C++17 or threading?

Ok.. Just loaded up the dRehmFlight software and used a MPU6050 and did verify that the SerialPlotter isn't plotting any data. Did manage to trace down the problem, which is kind of strange because it doesn't happen...

the pragma messages were added as a result of going to an updated toolchain in 1.58. 1.57 still uses the old toolchain. You should probably update to 1.58 now that its been released. Paul did issue a PlatformIO update...

Ok you made me look. Not sure why its giving a warning but maybe has to do with the pragma's used #pragma GCC diagnostic push #pragma GCC diagnostic ignored "-Wformat-truncation" /* Or "-Wformat-truncation" */ ...

According to the tutorial that @defragster pointed to: But with that said I did find that with the example I had to open the Serial window first to start the sketch outputting then switch to the plotter window to...

@KurtE - @sbfreddie Not sure this is still an open issue but decided to play a bit and see if I was having the same issue. So I picked up a BME688 put together a MTP sketch that does three things. 1. Reads data...

same here and yes @BriComp the horizontal lines are a bit hard to see in several cases, at least for me.

Sorry was off doing chores. No rest for the weary. As @KurtE said - never use LTO so.. the USBMidi test sketch builds with faster+LTO but has a couple of warnings:...

Ok surprised me :) Just installed 0.59.1 on windows 10x64 using IDE 2.0.5 nightly 3/11/23: Tool teensy:teensy-compile@11.3.1 already installed Tool teensy:teensy-discovery@1.58.0 already installed Tool...

That really is strange. I just did a simple setup with a KY-040 rotatary encoder attached to pins 1 and 3 to try and duplicate. I then ran the simple encoder example and it did not have a problem working: You...

Ok with help from @KurtE I changed the autosave delay to 10000 from 1000: I then compiled and uploaded your sketch no issues (just a test). I then removed a semi-colon and tried to reload the sketch and received...
