You're absolutely right. I misread it. Sorry.
If you just want to see the spectrum of the guitar sample, There's a variable that is set to 0, 1 or 2 when you push the buttons. It is initially zero. If you initialize...
You need to install the three buttons to use the complete example code. By default it uses SDTEST1.WAV as the audio input to the FFT. Each of the three buttons selects a different input.
// Left button starts playing a...
Just FYI: When I compile that code with Arduino 1.8.13 and TD 1.54-beta6, it spits out an error message early on in the compilation.

The adafruit BMP380 board has 10k pullups on the two I2C pins which may not be sufficient. Try adding pullup resistors of about 4k7 ohms to both A4 and A5.
Pete
Oh, I missed something. The bmp.begin() is before the Serial.begin(). It may be failing but unable to print anything.
Try this:
void setup() {
Serial.begin(9600); //Begin serial communication at 9600bps
...
Try changing bmp.begin(); to this:
if (!bmp.begin()) {
Serial.println("Could not find a valid BMP280 sensor, check wiring!");
while (1);
}
Just to make sure that the Teensy can "see" the BMP280.

What kind of audio are you using for line input? If you're playing from a phone or a PC, have you turned up the audio enough?
When I play audio from PC to line-in there's rarely any non-zero output even though I can...
I don't think the buffer size has anything to do with the 480Mbit/sec transfer rate.
I may be wrong, but I think the larger buffer size just allows you to send larger SYSEX messages in one large chunk.
Pete
// TODO: start a timer, rather than sending the buffer
// before it's full, to make best use of bandwidth
This means that, at the moment, it sends a message immediately in which case having a very large buffer is...
uint16_t can only store numbers in the range 0 to 65535. The compiler is warning you that it can't cram a number like 4406636708352ll into 16 bits. That number requires 43 bits which is why it has the 'll' on the end...
In your Churchorgan_samples.h change this line:
#include <AudioSynthWavetable.h>
to this:
#include <synth_wavetable.h>
It still won't compile but it'll get further along.
Pete
I missed another problem
if((L_Queue.available() > 1) && (R_Queue.available() > 1)){
Those should be >= otherwise you won't process anything until there's at least two buffers in each of the left and right...
The ADC values are signed 16-bit. This is why you see the large values such as 65369, it is actually a small negative number.
This piece of your code is wrong:
uint16_t (*buff_pointer_L) = (L_Queue.readBuffer());...
For example, in the read_all_data example, it uses this to instantiate the device:
Adafruit_BNO055 bno = Adafruit_BNO055(55, 0x28);
You would just change it to
Adafruit_BNO055 bno = Adafruit_BNO055(55, 0x28,&Wire2);...
I believe that all you have to do is change
*theWire = &Wire
to
*theWire = &Wire2
Oh, hang on. You don't have to change the library. All you do is reference &Wire2 when you instantiate the Wire object in your...
I have two versions of a MIDI library on my system. The one in the TeensyDuino distribution does not have BaudRate in the DefaultSettings struct (in midi_Settings.h) whereas the one I've installed in my libraries...
Ooops. I appear to be using an older version of the display which was set up as a shield for Arduino UNO and used parallel data transfer rather than SPI.
Pete
If you compile that code for Teensy4, and assuming that you add some appropriate code to call these functions, it will not generate any MIDI messages - it will only output debugging messages to the Serial Monitor.
The...
Which Teensy are you using?
Which code were you using and how was the display wired?
I'm currently playing around with a 240x320 ILI9341-based display. First, I got it working on an Arduino Duemilanove and then on a...
I didn't say you were inventing anything, but I couldn't see how you were getting useful waveforms from Pins 9 and 11.
Yeah, whatever. Now you're using the correct pin for the DAC on a Teensy 3.2.
But there's...
You're going to have to explain this in detail. Pin 9 is a digital pin which can also be used to generate PWM output. Pin 11 is a digital pin only.
So, it's a mystery how you can be seeing "the waves" on those Teensy...
Having dug through the DallasTemperature library again, I see that if getTempCByIndex returns -127, it is an error indication which means that the specified device did not respond. You should look for and handle this...
On the github site you say:
To me, this is a classic indication that your code is writing over the end of an array or in some other way clobbering ram. Changing the order of the include files changes the order in...
