Was kind of curious and it appears LittleFS can be used on the ESP32 but not Teensy version. Here is a reference that might help

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
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...
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) {
...
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:

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...
@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...
@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...
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...
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

While updating my version of Fabio Versano's FreeIMU library I was looking for some of Madgwick's old papers and came across the fact the Madgwick changed what we have known as MadgwichAHRS. This occurred with the...
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...
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...
