Buying a Teensy LC would have least cost - especially if you really use 5 of them. Not sure of any reason it wouldn't work as well as the others for this dedicated purpose? See this for PCB creation and DEMO:...

Done for now - Got Twin Drives Hacked in and working!!!! Duplicated setup code for msDrive 1 and 2 in loop() - and pass ptr to msc1 or msc2 to the func( UsbFs *myMsc )'s that need it ( mbrDump and volLabel()'s ) >>...

Some hacking here - esp with my odd powered hub that has internal device #1 of a 120GB HDD - then as coded it doesn't look beyond msDrive1. Also odd about the hub as before - once enabled the Hub/HDD backfeeds power...

PR prepped to update with latest and LFSIntegrity got pulled into PJRC tree. Copied those files to git.defragster\lfsintegrity so they match now for changes going forward.

Finally built here ... swapped PJRC git USBHost into sketchbook/libraries ... still fail Deleted that to use the td1.54b7 installed copy and IT BUILDS! { Maybe re-using the sketchbook folder left some debris? } ...

This was pulled for use :: github.com/KurtE/USBHost_t36 >> "This branch is even with PaulStoffregen:master."

Odd ... Maybe https://sectigo.com/cps-repository hasn't reported the cert details to MSFT yet? I see these unfilled filed looking at the exe?:

Awesome. Let me know if anything changes - the git.LFSIntegrity should match? We can manage any updates but that helps formatUnused look useful and improves/updates LFSIntegrity.ino.

The list of LIBS used looked right ? Unless I have an old copy? Seeing this makes it seem like a prototype is missing from ??? T:\tCode\libraries\USBHost_t36\MTPDevice.cpp:318:6: error: 'MTPDevice' has not been...

YAY for you :mad: - what am I missing :(

That is a hack that doesn't help the desc.h issue. It came up a beta or so back and it handy. Anything there adds to or overrides anything in the base boards.txt. Offline about now - will look for USBHost/MSC/MTP...

@all : new images of the updated T_4.1 is online :: pjrc.com/store/teensy41.html#pins

Yes - see : store/teensy41.html#pins That shows the Arduino pin numbers for the SDIO pins

Hoping to catch up with this soon - USBHost , MTP, MSC ... will have to find the current common sources and stop being distracted by life and new computer setup.

Just put a note on Frank_B's PR Print Hardfaults #535 - that would be good to have in Beta 7 release so a thread could be started to discuss and put it to use on T_4.x's. @KurtE - 4K bump was in the error detection...

When there is an error to result in a '-1' exit - the text "teensy_size: " should NOT be printed on the Error line so it gets proper color coding.

Quirks indeed ... It was noticed in beta IIRC that there was LARGE timing asymmetry in I/O value changes. That seemed to go away - or at least not be super extreme - perhaps that was early when I/O went from 'slow'...

And for mtp-test - looks good?: teensy_size: Memory Usage on Teensy 4.1: teensy_size: FLASH: code:140560, data:13176, headers:7212 free for files:7965516 teensy_size: RAM1: code:163840, variables:37696 ...

Good to know - so that is (current) 'fixed' MCU overhead - not something user code will affect - but takes space on the FLASH.

That looks really nice for used resources output! Not sure what 'text_csf' / headers is telling me?

Quick search at Sparkfun and Pololu don't show they have any PDM's that pop up ... The only breakouts at Digikey are two Adafruit MP34DT01-M ( and other one ) , though they have many PDM,Digital mic chips.

I was wondering the point of the code as well - indeed tone or PWM might give better results with less overhead.

Is this the whole purpose or just a part of the project? Is any code needed to run in loop()? Do the frequencies ever change? A Float value can be passed in and it looks like a value down to 0.7291667 (?) will work...

Yes - two copies - one in prior LFS and one added to the NAND code. Not all media uses it : FRAM, RAM, PROGRAM. RAM is a NOP - not sure about FRAM to just write may take less time to just write blank on request,...

On one of the NAND SPI chips LFSIntegrity had run leaving lots of dirs and files - died on delete of folder 24? Teensy still responds to USB CMD 'f' to toggle that. Running the new LFSIntegrity a recursive...

@Paul: NOTE for SD update to SdFat : transferred Arduino/Teensy drive contents to new machine here > Build pulled in Adafruit_SDFAT library instead of the Teensy one, had to delete that ( used for their NRF family )

Yes, the meaningful change is to blockisBlank() in two places ( NAND and LFS other) and the call change in formatUnused. I had a good compare post of the times - forgot to post as I ran off - came back with more info...

Because the uint64_t passes two sets of 32 bits and the printf as used told it to read them 32 bits at a time. One got the low 32 bit value held and the other saw the upper 32 bits of zeros.
