Oops missed this. Don't see it. Maybe its looking at like a HID device. Its not showing device class?

Could this be it: ---------------------- Device Descriptor ---------------------- bLength : 0x12 (18 bytes) bDescriptorType : 0x01 (Device Descriptor) bcdUSB : 0x200...

Short answer is that i2c_t3 doesn’t work with teensy 4.0 or 4.1 you will have to switch to just using standard Wire library. But I don’t think wire supports wire.stautus

Yes definitely Paul - HAPPY BIRTHDAY !!!!! ;) Enjoy your day :) Funny mine was yesterday the 28th :)

@KurtE - @wwatson Would think you would need a UsbFS pointing to each partition? Think it was like my thought that for each partition you need a addfilesystem(....,....,..., partition number) so it would know to...

At 24 pages, think that its going on the list of things to do :)

Cool. So many choices. Think volume stuff needs to be added to volume interface - would make it more transparent I think ?

Just ordered the one Kurt posted as well - told you I am in trouble when I get curious.

Yes it does - has the right components and same labeling.

To be honest - think it should as well. Would be good info to have available and inline with SDFat-beta

Yes please. Now I am curious which implies I am in trouble :)

Something like this: https://www.amazon.com/Digital-Receiver-Antenna-Multi-Picture-Display/dp/B07MBGTVFV/ref=sr_1_4?dchild=1&keywords=dvb-t+receiver&qid=1614605707&sr=8-4

Is this what you are trying to implement: Child Device 2 : HID Infrared Remote Receiver ? Be honest - I would plug it in with all the debug turned on and see what it recognizes and start from there.

@Frank B Might be easier to know what device you are trying to connect to USB host. When I was trying to add new devices I would start by turning debug on in USBHost, and the different .cpp files for the device -...

Just re-synched and seems to be working. Put in the SD Card Adatpter with 3 partitions: Waiting up to 5 seconds for USB drive 1 ^Waiting up to 5 seconds for USB drive 2 ^^^^^^^^~~~~:(Initialize USB...

@defragster Didn't have the problem with the java exceptions that you saw. SerMon would come to life if I closed it and reopened but would stop again. I did notice that TyCommander didn't have that problem if I...

@KurtE Just tried compiling for the T4.1 (VolumeName.ino) in the examples folder and got the following error: C:\Users\Merli\AppData\Local\Temp\arduino_build_281257\libraries\SdFat\FsLib\FsNew.cpp.o: In function...

@KurtE Fantastic job.... think duplicating the sub-library was the best approach and then modifing it. Will download and give it a try.

@defragster Thanks for confirming the issue -- glad it is not just me.

Not quite sure how that is being done but I did see in micros() looks like you have to wrap msec = systick_millis_count; with disabling the interrupt and then re-enabling it.

Guess that answers that question :)

@KurtE Ran a test with analog read in the interrupt and worked down to 20us. This makes sense since analog read is taking about 17us. Did get response on github discussion: So pretty much done until the next...

@KurtE My advanced c++ skills are limited to looking things up as I go :) Anyway, what you say seems to make sense, at least to me. Now just to decided where to put all this. At this point maybe stick to the...

Morning @all @KurtE - ambitious and good luck. But to your point on SDCards - think you are going to have to implement something similar if it has more than one partition. But I think if you get it to work with...

Morning @KurtE Yeah me too! within the interrupt it just calls off to analogRead - nothing fancy going on there. Was thinking about that myself especially since I have the test in post #19 as the base, but that...

SOLVED: Ok just to say thanks to everyone for helping and let you know that I finally tracked down the issue. It appears that problem is using analogRead is not interrupt friendly. The hang was in the...

Just messed up my sdfat lib as well just for a another data point for you.: This is for a SD Card with 2 FAT32 and 1 exfat: msc # Partition Table part,boot,bgnCHS,type,endCHS,start,length...

Maybe using the drive as the pointer instead of the volume so everything in MTP going to associated with the drive not the vol?

@KurtE Was toying with something like this for MTP but don;t think I am passing the right things: uint32_t sd_addFilesystem(FS &fs, const char *name, const char *volumeID) { if (fsCount <...

@Frank B Assume you are talking about the USBHost Shield 2.0: http://shop.tkjelectronics.dk/product_info.php?products_id=43 If you are I have the original version and it works for teensy 3 and 4 with one caveat. ...

Makes absolute sense to me - that sketch is coming in handy for testing.

Very cool = I just gave you last set of chances a try and they worked = both thumb drives came up - even the SD Card.

Thanks will pull down the latest changes and give it a go. Not even going to touch linux - having enough problems :)

@KurtE Just tried your updated MTP and this is what I am seeing. Look like it works for SSD: MTP_test sd_addFilesystem: 0 20006328 RAM1 RAM Storage 0 RAM1 199936 512 sd_addFilesystem: 1 200063f0 RAM2 RAM Storage...

Morning all Decided to start playing. Ran @defragster's updated sketch on 3 devices: (1) an old 2GB thumb drive (FAT16 only), (2) a 32GB Sandisk thumb and (3) my HP 120GB SSD. One thing I noticed is that the...

@KurtE Was just looking over your code snippet so this is a question - it may be buried but I don't see where you are setting up expartVol/partVol .begin for the different partitions and then setting a mscfs based on...

Trying a whole host of things but no luck. Hate issues like this reminds me of UncannyEyes! Going to go back and play with MSC/MTP!

@luni Found the problem - the program for doesn't like going to USB1 when using a T3.5 and T3.6. Removed it and got everything started working as before. Did test with a T3.2 but it hanging somewhere so the DCC++...

Funny it worked with the code I posted now must have did something to make it fail. Going to run a test just to see with time.h. EDIT: Something else must of broke. Just this test sketch and it works fine: //...

Nope nothing else gets printed as I am playing. BTW will it work with a Teensy 3.x Remember when I said it was working for a T3.5 well now its not working - argh. - no start up info from timer.h and no signal.

@luni Seeing exactly the same thing on startup as you: init 0x0 setPeriod(58) attachInterrupt() start out of curiosity I switched the prog track to use pins 3/11 just in case. No difference

@KurtE Did try and putting asm("dsb")'s in different places associated with the interrupts but still had the problem. Tried playing with volatile's as well but no luck.

Ok now have another interesting thing going on. I wanted to try with a Teensy 3.6 but as soon as turn power on with the sketch loaded the T3.6 is sending signals to the lock to move but its not suppose to. The...

Will give it a try - just after a fresh pot of coffee.

Oops - thats @Frank B's library = I added it get freemem for the T4.1: https://github.com/FrankBoesing/T4_PowerButton Sorry about that - forgot I was using it so distracted with the other problem.

Ok lets see if I can explain this without tripping over myself. A virtual timer is set up in Timer.h that calls off to IntervalTimer that does a attachInterruptVector. The sketch then calls off to: ...

Morning all Actually no, didn't get a chance to look - too many other distractions last couple of days :) I agree with you Kurt 100%. Oh - one thing I noticed is that if you put in a SD Card in a USB adapter...

Serial monitor seems to be hanging again similar to what happened in T4 beta testing: https://forum.pjrc.com/threads/54711-Teensy-4-0-First-Beta-Test?p=213179&viewfull=1#post213179 If I run this sketch: void setup()...

Thanks thought crossed my mind - so I tested yesterday down to 24Mhz. But as a double check after your suggestion I just tested at 150Mhz - still stopped after a couple tries. Even tried tried changing compiler options

Morning all @defragster - gave your mods a go and all seems to be working. 1. SSD 120GB - 2parts, extFAT/FAT32 2. SD CARD in adapter - 32GB - 2 FAT32 parts 3. 2 GB Thumb drive - 1 FAT16 All worked without a...

If anyone has any ideas please let me know. Ran of ideas on how to further debug.

@defragster - will let you do it = going get some zzz's now - been up since 4am

Damn - thought I posted the fix: // VolumeName.ino // An example of how to retrieve Fat32 and ExFat volume names using SdFat. // Works with SD cards and USB mass storage drives. #include "Arduino.h" #include...

Ok here is the fix for extFat: Waiting up to 5 seconds for USB drive Initialize USB drive...USB drive 1 is present. msc1 Partition Table part,boot,bgnCHS,type,endCHS,start,length FAT32:...

@defragster Wondering if its an issue with MSFT formatted drive. I put a 128GB SD Card in a usb adapter with 2 FAT32 and 1 extFAT. But looks like the exFAT is failing for some reason; Initialize USB drive...USB...

Now looking at the waveforms between the T3.5 and T4.1 when it works the command takes about 1.2seconds to complete and they look alike (Used a Salae Logic Analyzer). When it fails on the T4.1 the signal just keeps...

@KurtE Fantastic. I was playing with and trying to make it work like FAT by opening the root directory but failed miserably. Where did you find the rootDirStart?: msc1.usbDrive()->readSector(partVol.rootDirStart(),...

Just gave it a try and works for me. We all are really hacking away - but its working at least so making progress. Not sure we are supporting FAT16 - or should we? As for different types of FAT32 codes that easy...

@KurtE Fixed this now works for USB devices: msc1 Partition Table part,boot,bgnCHS,type,endCHS,start,length exFAT: 1,0,0x20,0x21,0x0,0x7,0xFE,0xFF,0xFF,2048,204800000 FAT32:...

Out of curiosity I did add a print directory (LS) for the fat just to see if it work: msc1 Partition Table part,boot,bgnCHS,type,endCHS,start,length exFAT: 1,0,0x20,0x21,0x0,0x7,0xFE,0xFF,0xFF,2048,204800000 FAT32:...

@KurtE Got it partially working msc1 Partition Table part,boot,bgnCHS,type,endCHS,start,length exFAT: 1,0,0x20,0x21,0x0,0x7,0xFE,0xFF,0xFF,2048,204800000 FAT32:...

@KurtE - @all Finished my diversions this morning and guess I am going to start playing with partitions again. This stuff is giving me a headache to be honest - a lot of pieces to the puzzle. @defragster Glad...

Thanks Kurt - right now by brain is mush working on multiple things at a time :) Need a break before getting back into it.

Question: To set up a volume say for an exFat partion I do a: expartVol.begin(sd.card(), true, 1); for an SD Card. Now, if I am using a usb drive (non sd). What do I do for a blockdevice or pointer to the...

Try pulling from Paul's repository for USBHost_t36 - I switched over to that for testing. Just looked looks like its like it should be the same though.

@defragster Maybe its using an outdated USBHost_t36? or maybe try it from Arduino IDE : Using library UsbMscFat-main at version 1.0.0 in folder: D:\Users\Merli\Documents\Arduino\libraries\UsbMscFat-main Using...

@defragster I am assuming that those libraries in T:\tCode\libraries\ are some linked to the libaries in T:\arduino-1.8.13_t54\hardware\teensy\avr\libraries?

Ok cool was just looking at this now - so now don't have to. Do have to so some testing with the changes though in MTP and standalone :)

Ok here is one for you all Out of curiosity I just downloaded it again but used Firefox. No issues with defender and my Norton pop-up came up and said it was a safe file. I added that rule a long time ago. Now -...

Not 100% sure. In post #435 @wwatson mentioned that the only thing you need in your libraries folder is: https://github.com/wwatson4506/UsbMscFat.. I did delete all the old MSC files - uSDFS, MSC/MSC2 etc. so that...

@wwatson - @KurtE - @defragster Just ran your test sketch in post #433 and it worked like a charm. Recognized exFATs and FAT32 to get the volume name. Have to go find my hub to test with again - keep loosing...

@defragster Nope the those lines are in my version. Note - never created a build.local.txt file that I remember but then who knows may have did that a long time ago and just got use to it being there. Going to add...

@defraster Don't remember ever having a boards.local.txt file there before. Anyway that is in there now for all Teensy's not the the T4.1

Item #1: teensy.exe is staying around 0% with periodic jumps to 0.1%. Java Platform SE Binary goes between 0% and 0.7% Item #2: see post #10 A couple things for Beta8: 1. USBHS_USBCMD_ITC(0) in usbhost_t36...

Did notice the new memory usage in both Verbose and non-verbose. In verbose I am seeing this additional info: Linking everything together......

@Paul Just downloaded Beta7 and pretty much saw what @defragster saw in post #4. I did one additional step. Before telling defender to Keep file I clicked on REPORT THIS FILE AS SAFE: Once you click on report file...

@KurtE Funny when I put in my SSD it showed the contents of the first partition as I expected. I was rummaging around mscUSB but I didn't see any linkages back to SDFat for the Volume commands that we need. So...

Not yet. Not sure how much of the vol and partition stuff is exposed in msc. Haven’t looked at yet

@KurtE Been searching the code and the help system as well but to no avail. Nothing I have found seems to return the volume name. Think @wwatson mentioned in an earlier post that he was doing something to get the vol...

@KurtE - @wwatson Decided to play around with the BufferedPrint example to see what it takes to write and read files from the partitions. Did manage to create 3 partitions that I can test with; SD Partition Table...

@KurtE Sorry for the delay in responding. Was busy playing and watching more snow fall :( Any tried to modify formatter but haven't broken the code on that one and wound up messing up my partitions on the sd card...

Taxes - yep - already did mine. Anyway get the volume directory was relative easy. SdFat version: 2.0.5-beta.1 Assuming an SDIO interface. type any character to start init time: 22 ms Card type: SDXC

@wwatson Thanks for the changes will play more with it tomorrow. May try to do a list files but intent really was to see if and how to get access via sdfat. But the use of sd.card was the key

Hopefully no more issues. Hope that list is getting shorter but have a feeling it’s getting longer.

Should have mentioned. Running Ubuntu 20.04.02LTS 64 bit on the PI4. Don't really have any other Linux systems. Probably can did out a RPI3 and see what I have on it and give it a try if you think its worth it?

Ok - just tried it on a RPI4 and its now working. Guess the order matters - 00 versus 49. Forgot to document but think you added an extra rule as well to the file.

First don't despair. I have had many UBLOX modules working with the Teensy (most 3.2 and up) and never had a problem. The first thing I usually do is use a Hardware Serial Port as opposed to using Software Serial. ...

Thanks - the dummy that I am. So with that ran it but I created 4 volumes 3 are FAT32 and 1 is exFAT. This is running the SDInfo without Partition info set up: SdFat version: 2.0.5-beta.1 Assuming an SDIO interface....

Morning @KurtE Was trying to implement your changes and found you already implement them in the repository example so.... Using just 1 MSC object ran into a couple of problems with some devices: 1. SD Card using a...
