Activity Stream

@ckahlo (and any others that may know): Would you happen to know how to use the payload key (AES) with the DCP? More information: in the interests of understanding how things work, I like to go through any...

Can you confirm that the device connected to your computer is T3.6 and the speed is set to 180 Mhz? No, I'm not testing with a powered hub at the moment.

I am setup for testing now. @mjs513 I am getting the same results as you. Everything seems to be working except un-plugging and replugging the flash drive. I can't remember, but has a powered hub been tried?

I also conducted the test with T4.1 as the device connected to the computer, and it ran without issue.

Alright. I've found something else. If I reduce the speed of the T3.6 connected to the computer from 180 Mhz down to 96 Mhz, the test always completes.

I have the PDM mic attached to pin 8 (Data) and pin 21 (Clock). Where do I move the data and clock lines from the Audio shield?

@mjs513 I performed your test as best I could---I was still using T3.6 devices. I performed the test 10 times, each time I power cycled the teensy connected to the computer, leaving the hub, flash drive, and second...

No, I'm talking about the inherent operation of the host controller. Look at the new_Pipe() function, you can see how the queue heads for all async (bulk and control) endpoints are arranged as a circular list. The host...

Actually I don;t believe that is the case. Take a closer look at the sketch. Only time a Midi message is sent is when one of the 3 buttons are pressed. and also look at the last line // MIDI Controllers should...

You're talking about this code? if (stat & USBHS_USBSTS_UAI) { // completed qTD(s) from the async schedule println("Async Followup"); //print(async_followup_first, async_followup_last); Transfer_t *p =...

Thanks for taking the time to test. I appreciate others taking this issue seriously. The reason your test doesn't hang is because your MIDI device connected to the hub is constantly sending MIDI. The Mass Storage...

No. If an endpoint (pipe) blocks, the host simply moves on to the next round-robin style. If a single transfer blocked everything else until it completed it would even block new devices from being enumerated. Any...

@yeahtuna regarding your midi sketch. Been looking at on and off most of the day and there has been something that has been bothering me about especially since I dont play with MIDI for any reason. I guess the thing...

Thanks for the helpful responses @radiohound and @MatrixRat. I've suggested using USB cables with ferrite beads and I'm told the error only occurs when using this particular MIDI controller so it's a bit of a head...

So, correct me if I'm wrong, but it seems that MIDI devices queue transfers that only complete once a MIDI event is received. So any other transfers that are queue by other drivers won't get called until after a MIDI...

Yes, using 3.3v for everything. The Airlift will take between 3 and 6 volts VIN. I'm even using 3.3v with the Teensy 3.5, and it works fine.

Ok got it working using the sketch from this thread https://forum.pjrc.com/threads/70227-USBhost_t36-MIDI-losing-midi-note-on-off-events-(Teensy-3-6)-during-modwheel-change?highlight=usbhost+midi+examples.

@KurtE - Had a chance to play with the MTP sketch. Some interesting results when playing with write sizes. Kingston DT50 32G, 512 bytes at a time: Start write file: write_test_file.txt length:1048576 Write Size:512...

Arduino have available a command line interface here: https://arduino.github.io/arduino-cli/ Direct link here: https://downloads.arduino.cc/arduino-cli/arduino-cli_latest_Windows_64bit.zip Example: Compile for a...

If lines 194 and 195 in midi.cpp are commented out, then the test completes. https://github.com/PaulStoffregen/USBHost_t36/blob/69b90727a5b028699b47910aa5cd6a0823de5f69/midi.cpp#L194

Are you using 3.3v as Vin for the Airlift? Remember Teensy 3's are 5v tolerant but Teensy 4's are not.

The build type is MIDI.

Was going to start a new thread but I am curious about MIDI as well. Wanted to experiment a little bit with MIDI and USBHost so I loaded the transmit example from Using USB MIDI on a Teensy 4.1: #include <Bounce.h> ...

Roland's XV-5080 has a N2012Z601T02 (600 Ohms @ 100 Mhz) on each signal pin of Midi in and Midi out sockets. Also possible that the receiving device is the culprit.

I like differential signals over (maybe shielded) twisted pair, for noise immunity. Any signals could be converted to differential signals, really, but they all require a little extra hardware (transceivers). Something...

I copied your exact code and only made minor changes for the busy and reset pins: #define SPIWIFI_SS 10 // Chip select pin #define SPIWIFI_ACK 8 // a.k.a BUSY or READY pin #define ESP32_RESETN 9 // Reset...

It would be nice if the audio examples that reference the SD card are fixed so that they at least mention the defaults for Teensy 4.0/4.1. Preferably it would make the defaults for Teensy 4.x be the default since...

Hi FLL-Freak, I'm an old fart too, can't stand the Arduino IDE and would dearly like to circumvent it. Did the work you did on creating your own makefile come to fruition? If so I'd be really interested to see what...

I am currently trying to solve a MIDI problem, it is with 1.57.2 I have tested so far. The problem is that the LaunchControl XL sends the slider and potentiometer positions at startup, immediately after power on. If...

The code I submitted works for either Teensy 4 or Teensy 3, controlled by a "#define TEENSY4" if you want Teensy 4. Here's the readRTCFrac() code for only Teensy 4: #include <imxrt.h> ...

Building for USB type - midi Does it work? Note: I know almost nothing about midi, nor use it at all. But tried opening the TransmitEverything.ino example sketch on a couple of day old Arduino 2 nightly build....

What USB type are you building for?

Update: as noted on another thread, there's already a call to sgtl5000_1.micGain(); in the code, which typically sets the gain very low (somewhere between +5 and +15dB, depending on which repo you start from). This is...

Yup, that sounds awful all right! But at least we're vaguely in control of the levels now. As you say, hard to shield the existing cable, though maybe you could get a replacement one which is better-made. Hard to be...

Yes, we wanted external reference capability. If you don't need that, there is also the MCP4822, quite similar 2 x 12-bit DAC with internal-only 2.048 VDC reference.

From nn28's first posting, so I am assuming they were powered up already with an unspecified voltage (but suspect 12 V) on Vin.

I don't have much of anything: Audio library, there were two different PRs to allow one to play a wav file from all Filesystems, not hard coded to SD... Again not overly critical. Cores: Looks like you have...

Hard to really know what is going on. As we may not know the whole setup including the setup code, what else is connected... But code too large: you would normally think that would behave the same for reboot versus...

I'm considering wrapping up what we have now as version 1.58. The main idea is publishing the new toolchain, updates for MacOS Ventura, and some bug fixes.... but intentionally not putting many new features into 1.58...

Hey, thanks a lot! I did not know about the # button previously. I have now edited the post with more information you suggested!

Chips like MCP4922 have a huge advantage (for some uses) that you can give the chip a stable reference voltage.

#include <Audio.h> #include <Wire.h> #include <SPI.h> #include <SD.h> #include <SerialFlash.h> #include <FastLED.h> #include <deque> //const int myInput = AUDIO_INPUT_MIC; const int myInput =...

Not sure if you are using a metal case for your midi controller, but that would help shield it. And using ferrite clamp chokes on all wires going to your midi controllers, including power, usb and midi. Chokes are a...

Are these virgin T4.1 that are presenting these problems? Or where they used in a circuit prior?

You can change teensyduino versions in the Boards manager. Second icon down on the left edge of main window opens that. Pull the scroll bar way down and you will find "Teensy by Paul Stoffregen". It should show, by...

After the Arduino build completes, the amount of RAM and FLASH used are displayed. You might have to turn on verbose output.

As stated in the post the code was for the Teensy 3.x. It also suggested that you look at the code for the Teensy 4.x.

I actually added those lines because it wasn't working properly, just in case... I let Teensy run over the weekend and there was no change in EEPROM values (nothing was written), so I assume there is no problem in the...

Thank you. I tried compiling using your code and I'm getting "Compilation error: 'RTC_TPR' was not declared in this scope". Is there a library I'm missing?

Another 2-channel option is MCP4922. Only about $3.00

It feels like something related to what you're doing in your ISRs, but that's just a guess. You don't need to disable interrupts when reading/writing EEPROM, so as a quick test, you could try commenting out those lines...

Yes, as mentioned Arduino IDE 2.0.5 is by default with 1.57.2, and I have been testing that today. But I could/would very well use beta if that provides help with the wireless mouse etc. and not too badly breaks...

Hi joshnishikawa :) .. just picking up this older thread and wanted to send you my THANKY YOU, as I always use (and love) your library, works awesome, great ! fyi: Using your TouchSwitch (on-off_stable example) The...

@Garug - not sure here... Especially if for example your Arduino 1.x version and 2.x version are both running the same version of Teensyduino code. Then I would think they should give you more or less the same...

Thanks for the reply, KurtE. The RawHID was a red herring. I know all hubs are not created equal, and I tested with a few more hubs and could not reproduce the issue. The second test with the devices set to USB MIDI,...

@yeahtuna Quick thing on your sketch, which may or may not help. On the second teensy, it logically looks like it boils down to: void loop() { myusb.Task(); if (rawHIDTimer > 50) { ...

Thanks for trying to help me, Joe... That Int in the name was actually meant as eeprom_readInteger(), eeprom_writeInteger()... But I have a few ISR in the code, that's why I'm disabling and re-enabling interrups, when...

Paul posted this code: extern "C" int _gettimeofday(struct timeval *tv, void *ignore) { uint32_t hi1 = SNVS_HPRTCMR; uint32_t lo1 = SNVS_HPRTCLR; while (1) { uint32_t hi2 = SNVS_HPRTCMR; // ref manual...

Here's a sketch to show that the USB Host MIDI driver is causing the Mass Storage driver to fail. Both teensy devices should be running the same sketch included below. If the test is performed without the second...

That is not the serial port, and it's just an illustration to get the idea across. The first teensy is of course attached to a computer. It looks like the real culprit is the MIDI driver. I'll post an updated test.

Not sure that would ever work the way you have it set up. As far I as know you are only going to be able to access the mscDrive if its hooked up via the USBHost port not the serial port. Running the same sketch on the...

It's really not possible to help without seeing a complete program, so please try to reduce what you're doing to a small, working program that shows the issue. With that said, does "Int" stand for interrupt in these...

Tried with a different USB hub and it seems to be working fine.

You may also want to look at https://forum.pjrc.com/threads/72233-OTA-through-Ethernet-with-Teensy-4-1 for and example using FlasherX to perform updates over the ethernet interface. The way this works is that as the...

So actually I don't need to write to EEPROM at all, but EEPROM changes randomly on every restart when my code is running... Here, first at address 30 the value 250 is zeroed after a reboot, then at address 32 value 6 is...

Here is another example - I wrote 4 at address 26, but after turning Teensy off and on, I got a value of 0 at address 12 ... Then I just turned Teensy off and on again without any write and I got a random value of 6577...

I just wanted to say that JackTrip is an awesome project, never heard of it and I will be digging in for sure. Exactly what connection is needed electrically to connect an external clock to the Teensy? I know I've...

Hi Joe, thanks for your time, your code is working as it should, of course... Not sure what is happening in my case... Just to test the issue I'm trying to read EEPROM at the beginnig of the setup(), and then...

I've also got one of these old Kingston Datatraveler drives (a 4GB). When connected directly to a Teensy 4.1 it will not work at all, not matter how long the timeouts are or if the initial reset is skipped - the...

Thanks, with the help of /Users/{username}/Library/Arduino15/packages/teensy/hardware/avr/ and Go I found the relevant files It seems the Arduino IDE 2.0.5 is by default with 1.57.2 also after void...

As far as I can tell, in the code printed, you are using the standard SPI pins (MOSI = 11, MISO = 12, SCLK = 13). Note the Teensy LC, 3.2, 3.5, and 3.6 allow you to use alternate SPI pins (MOSI = 7, MISO = 8, SCLK =...

Well I've been hacking with this some more and I got this ADAT going on SAI3 (Teensy 4.x only), that's right the SAI3 used for Medium Quality Sound (MQS).:D Tx_Data0 out on Pin 31- EMC36, There is also MCLK3 on Pin...

I just wired my Teensy 4.1 up using Adafruit's WifiNINA / Airlift library, and it seems to be working fine for me. I did not have any luck at redefining SPI pins, although I didn't try too hard on it. Here is my working...

Is only a single QSPI/PSRAM chip needed? Most of those pads look awful. As long as they aren't shorted there might be a way to get one PSRAM working. refer to the T_4.1 card and get the orientation right ... The...

Yes and since this one is R2R, that dovetails with another lab where they have to build a 3-bit R2R DAC by hand :cool: My laser galvo project is AC coupled, but if I decide to do anything where they have to measure...

I've got labs already using the 4725 but with either an Arduino or a RPi; however, I've not been able to drive the I2C bus fast enough for my tastes at full bit depth. For teaching purposes this is ok but somewhat...

Arrow has IMXRT1062DVN6B and MIMXRT1062DVL6B. They aren't what you want but are the only thing I've seen in stock that can work for Teensy.

Here is a minimal setup to cause the MassStorageDriver to fail. Both teensy devices should be running the same sketch included below. If the test is performed without the second teensy connected to the USB host...

@KurtE - that worked. Thanks. Want to test some hard drives as well. They are always faster but probably not practical for remote applications.

Sorry, there is not much of checking in this code. Like most of the commands in that sketch, it runs off of the currently selected drive. SO in Command prompt after comes up if you use the 1 command 1<cr> It will...

@yeahtuna Incorrect - at that point no SCSI command has been called...
