By "dac" I Meant the pt8211_2. Sorry if I wasn't clear.
I also eddited the output of the graphic design tool so the usb and pt8211_2 are specified right off, then the patchcords from the corresponding mixers to these...
back to my original sketch, it now provides usb audio when usb and pt8211_2 is specified, but still no audio from the dac. I tried manually editing the definitions file to put audiooutput_pt8211_2 and audiooutput_usb in...
Not testing with a scope - using a simple a speaker attached to the PT8211 board per the picture. When it doesn't work I get NO sound what so ever.
Right, my results exactly. When it works it works both ways, when...
Thise sketch ran before I tried manually editing that c file. Since then I have removed the arduino environment completely from my system, rebuilt it with teensyduino 1.57b1, and it now does this weird loop where it...
post in msg #63 indicated that you were wired for pins # 7, 20, & 21
Nonono, I didn't rewire the board. It's just that it was working with the other i2s port defined, which means those pins are busy doing other...
And now I have rebuilt the entire build system, and now when I try to compile my working sketches I get an error related to 'BUILTIN_SDCARD' was not declared in this scope. Yeesh.
Out of the frying pan...
I tried commenting out the reference above in output_pt8211_2.cpp, then I tried removing the i2s2 object in my code that was there just to make ti work. When I recompiled I had the exact same...
I just installed 1.57b1 and I still get the same result when building knobby. Commenting out the references to i2s2 (leaving only usb audio and pt8211_2) causes no sound output from the 8211.
Just trying to help.
Wire2? Oh no, more stuff to learn!
Right now I've not even enabled port1. I'm back to working on the synth engine because that's more fun than dealing with linker issues :) I have to get the sequencers and...
It's alive! The sound is bauhaus, not my creation, but I have since used the AudioObjectI2C workaround to get the sound working (for now). Ultimately I need 7,20 and 21 for serial, but they're ok for now.
Thanks Paul...
I guess we're both lost then, because I don't know from Windows. I haven't used it since I retired nearly a decade ago.
I don't know if this is a clue, but if you build the above sketch with usb audio out as well,...
This morning I reproduced the problem on a t420 thinkpad with a fresh install of ubuntu 20.04 focal fossa. I did not change any of the machine's configuration other than downloading and installing arduino1.8.19 and...
Here's the /tmp files for the build, and the code (which results in no output). Thanks again.
#include <Audio.h>
#include <Wire.h>
#include <SPI.h>
#include <SD.h>
#include <SerialFlash.h>
That's the thing - it's not the 8211 chip that's flaking out. Withouot those object declarations, there is no data output from the teensy on pin 2. Adding the 12c object enables pin 2, but also puts data on pin 7 (which...
I don't get it. Thanks for your help, this one has beaten me. I still get nothing when I try your sketch, and my system is pretty much a bare teensy and a dac. I do have two 8MB ram chips installed. Any chance that...
Problem with the 42448 is it's unobtanium and will be likely for the next two years. The 8211 is available, inexpensive, and could be very usable if this mode is supported by the i2s_octal object. Of course, that...
Sorry, but that doesn't really help me. I'm not using Windows so it's kinda hard to jibe those paths, and as I mentioned I already reinstalled yesterday both the latest non-2.0 version of arduino and the teensy 1.56 I...
As I said, engaging any of the "i2s_quad" connection makes this work, and there are no other pins connected yet, so it does work... but only in conjunction with one or more of the other i2s ports ALSO being connected in...
From another thread I found the below sketch, which sort of works. If you uncomment ANY of the 12s_quad connections the whole thing "just works" as mentioned in the other thread. However, I am using the pt8211_2...
Nope, I see no warnings for competing audio libraries when I do this, nor do I see any adafruit files marked "audio.h." Looking into that folder, all I see are PJRC headers.
I just put the chip on an 8 pin adapter...
What is this "Audio-master.zip" file? Where do I find it? I found this thread and am having the exact same problem (nothing on pin 2) and so am anxious to fix it, but how?
My pt8211s arrived yesterday so I was...
Can't you just feed a straight signal into the envelope using a dc source without having to use its ramp time parameter?
Sure!
I'm not sure why you're unable to modulate your filter freq with an adsr, in your...
