Activity Stream

I finally have the guts to test this and start playing around as I have been doing ALOT of reading (still don't understand much but know more that I did a few weeks ago). I want to thank miciwan for the guidance and...

I've added it here, with a link to this thread.

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.

Weird. The library code seems to be quite elaborated. Would be surprised if it has such bugs in it. Maybe you changed something unintentionally while porting stuff?

p#494 sketch looks Great! Grabbed a fresh 128GB SD card and will make it Multi Partition. I thought to do something like procesMSDrive(1, msDrive1, msc1); rather than Dupe - but time was limited and wanted to get...

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......

I added example USB Passthrough sketches for DAC2 Pro and DAC2 HD. This effectively turns either HiFiBerry board into a 44.1kHz 16-bit USB sound card for the PC. To load these example sketches, you must select 'Audio'...

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.

I just used a small bluetooth audio transmitter/receiver bought for a few bucks on aliexpress. It uses an usb connector for powersupply and has two audio jacks. One is for the RX and one for the TX function. A small...

But I think this will just be a alternative to do switching by patching AudioConnections https://forum.pjrc.com/threads/60062-Dynamic-Audio-Connections?highlight=dynamic+audio+connections but in a more elegant...

I have the same problem as well. I commented out all the Serial.print and processor statistics. When it's in FLANGE_DELAY_PASSTHRU mode (logic 1 on pin 1), the audio is clean. When the flanger is running (logic 0 on...

Yes, but does it print anything later while you are playing with the commands and getting the error? If so, the library might mess up some intervaltimer settings.

In the SMALL program source code, you should have FLASH_BUFFER_ADDR = (FLASH_SIZE / 4) In the LARGE program source code, you should have FLASH_BUFFER_ADDR = (3 * FLASH_SIZE / 4) Is that what you have? Which...

I was able to get it to install only when the Arduino IDE was installed in its default location. (I used to have it installed on a different drive than the default. Teensyduino did not accept the directory entries...

As aside about switches - its been briefly mentioned above I think, but hard switching of audio is going to produce potentially loud and annoying clicks, since truncating a waveform is equivalent to the sound of a...

@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

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...

That is exactly how c++ template works the AudioCrosspointSwitch is initialized with AudioCrosspointSwitch<4,8> crossSwitch; which is a 4 input 8 output AudioCrosspointSwitch note.

The "dsb" is only effective for very short ISRs. The one used by the lib is probably long enough. (But this should be fixed anyway I'd say) Did you try to look if the library calls the functions from timer.h after...

Hello Rolf, fantastic work. I’m really enjoying see the progress on this. I love how informative your display is, and how it gives the user lots of real time feedback. Do you have any advice or resources on how to...

@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...

there is this one https://github.com/macaba/Audio/blob/master/mixer_crosspoint_16.cpp https://github.com/macaba/Audio/blob/master/mixer_crosspoint_16.h from macaba...

Wondering if you ever figured out what the problem was for you joystick. Only my up ( 1- i think) isn't working, and if replacing it was the fix for you id order a handful more.

Ah, interesting! I'm not sure I'd know exactly how to work this into the Teensy audio lib. Unfortunately I think the larger issue for my application is that I believe it's 1 in, multiple out, correct? What I'm...

Just wanted to rule out if it was a PC issue or not

This is a really intriguing idea, to just use ethernet as a raw serial-like byte stream at 100 Mbit speed. Or maybe as a raw packet delivery? If the ethernet mac is configured in promiscuous mode and automatic...

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

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....

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.

@DM5SG: EER transmission/polar transmitter is exactly the idea that came to my mind when FrankB wrote that excellent FM transmitter code! Would be nice to hear more on your developments! Maybe it would be worth coupling...

It wants to include some T4-Powerbutton.h? Not included in the zip...

I have a untested solution that is based upon AudioSwitch_F32.cpp from Chip Audette, OpenAudio library it's basically a Crosspoint switch (not mixer) AudioCrosspointSwitch.tpp /* * Created orginally: Chip...

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: ...

Although i appreciate the suggestion, there must be a reason for this problem on my computer that I hope someone may have an idea towards debugging?

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...

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()...

This doesn't actually work. It get you as far as the diags of the internal functions of the chip and I have never had trouble with that. It runs all of the stages of the tests but it stops short of actually connecting...

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...

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

Could it be a timing issue, Teensy 4.x going much faster? In order to rule out, compile for a much lower speed similar to Teensy 3.x.

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...

try another PC, could be a windows issue

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

I am in serial mode, I also tried whilst in mtp mode. It is not that it doesn't print to serial, it is that the device doesn't even show up on USB or run blink

Maybe Teensy is transmitting "*** ONLINE ***" before your PC is able to complete USB detection, and then you interpret the lack of that message as the USB device not working? But that doesn't explain needing the press...

I verified your sketch on a T4.1 and with or without the analogRead(randomVar ); line, it shows a serial USB device . Did you set Menu > Tools > USB Type to Serial? Using Arduino 1.8.13 & Teensyduino 1.53 on Windows...

Generally, for strips having more than 3 DotStar LEDs, you want to power that strip externally. You don't want the propshield board to supply significant current to DotStar strips. See this page for more info how to...

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 ) >>...

GOOD NEWS! Looks like it was used a year ago for USBHost testing. Now it just needs to be coded to bring up a second drive as well. My 120GB HUB DRIVE is ExFat and now works - seems to have Vol Label - and it...

Yes, thats the same what the Reference manual says - everything but the max 960000. I'll update that value. Thanx :)

int velocity = map(peak, thresholdMin, 1023, 1, 127); Serial.println (velocity); usbMIDI.sendNoteOn(note, velocity, channel); Yeah, how can you be getting those values at all? If you are then the MIDI...

Hello again, I fixed the issue by adding an amp in my audio graph and using the amp gain to achieve the intended function. I'm just going to set sgtl5000_1.volume() once in setup() and then leave it alone. Maybe I...

In the other hand - what do i do with 30+ Cards...?

I wonder if in the cases where you want to simply have the detector stand-alone outside its not easier to add a simple bluetooth transmitter that is connected to the phone-out of the detector ?

That sounds interesting. I have been thinking about this while waiting for all my parts to arrive. Are you using a module like HC-05/06? I was wondering about using an ESP32 as a co-processor (it would relieve the...

Your servo error outputs will need to be open collector. Most of the error outputs I have seen are OC and pull the signal low on an error. If you want to wire OR them, you will need to set the EStop input to NO. ...
