Actually I received a response on github from Bill... Now there is not a leak as the new is not actually allocating memory... As the code like: m_fVol = new (m_volMem) FatVolume; is actually just assigning the...

I sort of started a thread a little bit ago: https://forum.pjrc.com/threads/66338-Many-TLAs-MTP-MSC-FS-SD-SDFat-LittleFS-UsbMSCFat-to-work-with-each-other-8) Where I was maybe setting up for some integration stuff... ...

@wwatson - Sounds great. @all as I mentioned over in the MTP thread (https://forum.pjrc.com/threads/43050-MTP-Responder-Contribution?p=271721&viewfull=1#post271721) I am playing around with seeing about the...

@mjs513 - Yep I am also thinking a smaller test with fewer Storage types would be nice and/or split some of them into multiple tabs... And yes right not I am still playing with the MSC multi partition sketch...

Glad you found the issue... :D Wonder what is different between T3.x and T4.x? Or does something in your interrupts also touch the Analog? Sounds like maybe need test case to see and maybe the core code needs...

@all - Sometimes hard to know which thread to discuss things like integration of MTP amd MSC... and the like. I am going to try doing some additional changes to my branch of the code to add some more support for...

Thanks @mjs513 will probably look more in the morning. Today I also hacked up that function some more that printed that data, and used digital Write high/low with pin 0 for the whole duration and pin 1 around each...

@defragster and @mjs513 I am sort of curious about fragmentation works ;) For the Fat32 volume: I mucked up the beginning of the method most all of the class variables int32_t FatPartition::freeClusterCount() {...

Full current sketch, Note I commented out the earlier calls to get sizes... Waiting up to 5 seconds for USB drive 1 ^^Waiting up to 5 seconds for USB drive 2 ^^^^^^^~~~~:(Initialize USB...

So I tried adding in the above test sketch currently just to the FAT16 and FAT32 section code like: for (uint8_t i = 1; i < 5; i++) { switch (partitionTable) { case 11: case 12: { ...

Maybe the code in the sketch is wrong... It is not applying the partition... I am going to move those calls into the sections by partition type and see what I get... Looks like we crossed posted. I am going to...

Something does not appear to be working correctly at all with the freeClusterCount: int32_t FatPartition::freeClusterCount() { #if MAINTAIN_FREE_CLUSTER_COUNT if (m_freeClusterCount >= 0) { return...

@all - Another quick question: while starting to look at why the free space is TAKING SOOOOOOOO LLLLOOONNNGGG I noticed in the SDFat code:...

Quick note: I am thinking it might make sense to add the VolumeName.ino as an example sketch to maybe MscFS.h project. That way we can all keep track of it? Make sense?

Morning, Try picking up the latest UsbMSCFat project - I added a hack into it that if you ask for the Used size, twice (or more) it remembers the first call to it, which we do as a debug message at the time we add...

Thanks @defragster, I updated to your version. I ran again, still real slow on my older thumb drives: Waiting up to 5 seconds for USB drive 1 ^^Waiting up to 5 seconds for USB drive 2 ^^^^Initialize USB...

Just an FYI: I updated the Volume name sketch to also print out the total size and used size sort of plus elapsed time to get them for the different partitions: // VolumeName.ino // An example of how to retrieve...

@mjs513 which code fragment... MSC or MTP... So far in MTP I have not converted the main code to try to do anything with partitions, other than so far I am printing them out and I am able to get the first volume ID. ...

Might really help to understand what exactly is your setup? Windows? Linux? MAC? ... What version of Arduino are you running? What version of Teensyduino are you running? Anything changed on your machine, like...

@wwatson - not sure, about NTFS here. It looks like both partitions have type=7 which I believe is exfat. although looking at:https://en.wikipedia.org/wiki/Partition_type It looks like type of 7 could be either. ...

Any luck? Looks a bit complicated to jump in... I prefer easier things like MSC and MTP :D Is it easy to setup and see failure when you don't have the hardware? Steps, and what to see when it fails versus OK? ...

Updated to fix the Fat16, also implemented a one call to find volume label. And did some more gratuitous changes to have a function called by loop to process a drive, as to not need to reproduce it for more drives......

Another quick note: I updated my sketch to the last one @defragster and found it was using the old non working Fat16 code. i.e. the one that was reading the boot sector and appears to always be: NO NAME Will fix and...

Good morning again: Just for the fun of it you might try adding the asm("dsb"); somewhere... The reason I mention it, I have been bit several times where ISR gets triggered multiple times for the same interrupt....

Some More not fleshed out thoughts on MSC and Partitions and FS... I first off think it will be great all of the pieces in place and part of Teensyduino! What I am sort of wondering is if it makes sense to have a...

Good Morning! I have not had a good chance to go through all of the code: I don't see anywhere that you call attachInterruptVector, but if you did, I would probably make sure all of my interrupt vectors had...

Good Morning all: Sounds like we have things coming along well here, to understand some about partitions and getting the volume label. :D But our test has not handled SD Cards with multiple partitions ;) For...

My exfat was failing as well, will look tomorrow unless someone beats me to it.

Have Fat16 working I believe at least for USB, have not tried with SD yet... // VolumeName.ino // An example of how to retrieve Fat32 and ExFat volume names using SdFat. // Works with SD cards and USB mass storage...

Hi @defragster and others... Thought I would show so more stuff that is not working :D // VolumeName.ino // An example of how to retrieve Fat32 and ExFat volume names using SdFat. // Works with SD cards and...

Note: I have been playing some with adding Fat16 maybe stuff and not finding the VolID... Some output currentlly: Waiting up to 5 seconds for USB drive Initialize USB drive...FsVolume::begin(20001b28)...

@all - Wondering in my above Partition table dump you see: msc1 Partition Table part,boot,bgnCHS,type,endCHS,start,length 1,0,0x4,0x1,0x4,0xB,0xFE,0xC2,0xFF,2048,8192000...

Hi @mjs513, I slightly hacked up your sketch, by moving a lot of it from setup() to loop() with a wait at the end of loop() for user to enter character. That way you can hopefully rerun. I also have it wait up...

@all... I am winding my way through the different layers and trying to figure out how to get USB Drive partitions to work. It might be nice to be able to do something like: today the VojumeName.ino does: if...

Glad you have some building and ready to play :D Did not get as much done yesterday, but will now try to see if I can get this MSC volume code and the like to read from all 3 partitions on my USB stick...

Take this with a grain of salt, but what I am planning to look at includes: In the sketches we have: msController msDrive1(myusb); Each one of these is for a physical USB drive, I believe it claims the device at...

Note: the get volume label code was not working for me as probably timing. My USB is connected through HUB and so takes a bit of time before all of the stuff is setup. So I have it check to make sure the drive is...

As far as I know it should work. The code just figures out which Serial port gets passed in to dxlInit: void dxlInit(long baud, HardwareSerial* pserial, int direction_pin, int tx_pin, int rx_pin ) { As the AX12...

Sort of an old thread to resurrect. But by PMs been asked if I could convert the board to Altium... Not sure if you would gain much. The whole design: I did try to export the board layout to Eagle file in...

Mtp serial still need the usb_desc.h stuff copied in

Thanks @wwatson - tried the sketch, but the two drives I tried were exfat... Will try again. Thanks for the hints: I verified that in my debug outputs, the first calls msReadBlocks is in the this case is from a...

@wwatson @mjs513 and @all - my eyes are mind is not seeing some things... For example: I fixed my USB thumb drive partitions to not use extended partition... I turned off USBHost_t36 debug (in that header) but...

@... I have been playing around and understanding some more with the MSC stuff and partitions... If you run the sketch SdInfoUSB it will print the partition table stuff (Block 0). My output is way too much to...

I tried formatting a thumb drive to have 3 partitions, A Fat32 primary An extended partition table With a secondary partition with Fat16 and a secondary partition with Fat32 And my MTP with MSC, goes BOOM.....

@mjs513 an d @wwatson I will try playing some with that. Have anyone tried doing some of the same type tests on thumb drives or the like? I think I will try to partition a test thumb drive and see what might work......

@mjs513 - Not a problem... Hope not too much snow! Here it is raining and upper 40s... Will play more, but may want to switch gears to see about partitions on USB disks, which is probably more interesting. Also...

For the fun of it, I thought I would see if I could get it to read an ExFat one... I think this one sort of works for it. Probably a real hack, but... When you are dumping out the top partition table, I keep the...

@defragster - Looks great. Interesting with Low memory availability messages, I assume they most use a percentage... As 4K free on an LC would be 50% ;) I see the changes were pulled in

@... @mjs513 - tried you sketch above with a few cards. And it looks like it dumps lots of interesting info... Tried reformat 32gb SD to exFat. As you mentioned not able to read that data (yet)... Side...

@mjs513 @wwatson - looks like you are having some fun. Now to figure out how to integrate this with MTP :D I was happy yesterday to be able to plug in USB drive and it shows up and unplug it and it goes away... Now...

I put in a fix for now... Which is during the reset when the host asks for Storage IDS, I check to see if the name has been removed and if so it skips that slot... So now when I remove the drive it updates to not show...

It appeared to work on my RPI4 with 64 bit... looked good when I did ls -l /dev/hidr* Plus I told it to program the keyboard one which the reboot worked and so did the terminal monitor. Thanks (Now back to my main...

In case anyone wishes to play along. I have added some code to the MTP-Test with the MSC stuff where your define for including it value > 0 is the Max count of USB drives you wish to use... I also now have code in...

Was able to substitute the usage of MSCClass for the UsbFs class and that appears to work. I just updated my branch (warning left the define = 2, so will require the additional libraries. But with this I have a USB...

Looks like sort of a pain... But you got to to do what you got to do :D

First attempt is to substitute MSCClass for UsbFs and it compiles and runs for 1 item... Again hard to know if should talk about it here or MTP or... But my MTP test code is setup now like: #if USE_MSC_FAT > 0...

As I asked in the MTP thread: My next question to self and others maybe other thread is to support multiple MSC drives, I was using the global object (MSC) to add the one MSC object as is in the FilesUSB object. ...

My next question to self and others maybe other thread is to support multiple MSC drives, I was using the global object (MSC) to add the one MSC object as is in the FilesUSB object. Thought I would try the stuff out...

I wonder if maybe you may want to play around with the different pin configurations information like speed, or drive strength... i.e. look at the RM for the different IOMUXC_PAD_ values like DSE, SPEED

Now hopefully will get a little time to play a little more and see about defining multiple MSC objects. Also see about them coming and going... Sort of along the line of SD card being inserted. Then wondering...

Decided to go ahead and check the other two regions as well and error out. Also print out message... Feel free to change anything :D

I submitted a PR for first pass: I have an RA8876... test sketch that did a picture embed. That compiled fine with PROGMEM defined, but if as I have now, commented that out, it errors out the build. I did the...

Sounds good, For the fun of it you might try a simple on your machine like: grep hidraw /etc/udev/rules.d/*

I took a look and there were a few things I changed and it now does not crash :D In the file RF24.h The SPIClass object I don't initialize in header as you are doing it in constructor: SPIClass *_pspi;...

Thanks, Will play soon, trying to help someone update the RF24 library right now to handle multiple SPI ports.

I will take a look, I remember from my other size program based off of Franks stuff (https://github.com/KurtE/imxrt-size) simply returned -1 from main which caused the build to error out.

@mjs513 and @wwatson @wmxz @paul - That is why I started playing and why I started that other thread. Sometimes hard to know what is going to happen when you try to integrate several of these sub-systems. Or some of...

Looking good, I will have to try it out. Wondering, In my size program I put check in for in your case free for local variables if it <=0 the program returns an error status don't see it in this code base. I...

Another issue came up today in the thread: https://forum.pjrc.com/threads/66335-MTP-dependency-issues-w-Teensy-3-6-and-SDFat-2-0-4?p=270956&viewfull=1#post270956 in there he is trying to enable the use of UNICODE...

I have done a little playing here with the MTP-test to add an MSC drive. I turned it off by default as you need to install the libraries mentioned here. I also did a Pull Request to change the #define that was in...

@WMXZ - I have a package coming from digikey with some more external sdcard units... For the fun may play with a few, probably won't get up to 6. And yes you would need to hook up extra pins for each of the card...

Sorry, I am not sure if the main owner @WMXZ of the library has looked at Unicode stuff yet. I will try to take a quick look, but busy playing with other stuff :D

Have you looked at using the Adafruit library? Adafruit_SSD1306 One of it's constructors: Adafruit_SSD1306(uint8_t w, uint8_t h, TwoWire *twi = &Wire, int8_t rst_pin = -1, uint32_t clkDuring...

@mjs513 - I totally agree that in many cases posting to a thread specific to a library for something specific to that library... But was wondering where for example would be a good place to post things that maybe...

Hard to say without looking through all of the changes. And checking any other places that do something funky... You might try embedding a copy of your current library changes. Could zip them up and add the zip...

Radiohead does support multiple SPI buses, at least the RH_RF95 does. I played with this a long time ago. Where in my case I used SPI1, so I included: #include <RHDatagram.h> #include <RH_RF95.h> #include...

If it were me, I would install the latest Teensyduino beta from the thread: https://forum.pjrc.com/threads/66182-Teensyduino-1-54-Beta-6 This has some better support for SD and the like... Plus some of the stuff built...

Good, It also might have worked if you had made sure Arduino was not running and the teensy was not plugged in. Then when you plug in the teensy the rule should fire... Was going to upload the file here, but it...
