Thank you Paul! So what would be a good rate that would provide decent bit resolution?

Im curious what the maximum cycle rate is for the PWM pins on the Teensy 3.6 are?

I tried using the Altsoftserial library and example with my current hardware set up of the Teensy 3.1 soldered to the AudioBoard with the Flash chip on that as well. Unfortunately, I am getting no serial output. I am using the included example sketch directly from the altsoftserial page...

I understand Paul. It would seem then that the AltSoftSerial option is my best bet. Also due to the fact that my Teensy is already soldered to the audio board in question. So I have to use pins 20 and 21 if I want to implement the AltSoftSerial option? Or can these pins be changed? Thanks...

Paul, Thank you for the help! So just to be clear, As long as Im not using the SD lib / SD card reader on the Teensy, then I can get away with using the Serial2 option? I have no use for the SD functions as I am using the Flash chip on the audio board for my storage. I only need a baud...

Here is my current situation: I have a Teensy 3.1 mounted to an Audio board. The audio board also has the flash chip attached to it. I am using Serial1 for a 4D Systems LCD screen. And from my understanding, The Audio Board uses Serial2 and Serial3 for its operations. I need an option...

Im curious then, how did you test those chips referenced on the GIThub page? How are we to use these larger and smaller chips that are claimed to work with the Teensy? Thank you!

I am curious how to use the other approved and tested higher capacity flash chips? The 256mbit chips dont come in the 8SOIC package. Instead they come as 16SOIC and 8-WSON. Wondering if the 8-WSON package could be soldered onto the pads that are on the Audio Board or not? Would be most...

I am curious what the largest FLASH chip that is an 8SOIC package that will fit the pads on the audioboard and that the new serial flash library will work with? Or what other options do I have for using the available larger chips that the serial flash library works with? Such as the Winbond...

That was the issue! Thank you! And yes, I can understand how you never as much detail as possible to solve an issue. I often times forget some of the things I think are trivial. My apologies. I will now see if I can play the files now.

I should also note the following. I have reformatted several cards of the same type in the following ways. I have used the format utility on Windows to format the cards as such: FAT(32) - 4kb allocation size FAT(32) - 32kb allocation size FAT - 64kb allocation size None of which had a...

Understood. STEP 1 : Plug in Teensy 3.1 / Audioboard with the attached W25Q128FV chip. SD card is removed. Running the EraseEverything sketch from the examples. Code and output below. CODE: #include <SerialFlash.h> #include <SPI.h> SerialFlashFile file; const unsigned long testIncrement...

Any thoughts or suggestions?

I thought I did provide all the details. If by providing the code used, no I didnt do that. As I am using the exact example located within the Arduino example code that comes with your libraries. But I will post it here. The files on the SD card are named in the following way.. 01SD.raw ...

Guys, I was able to get the hardware scan to work properly. After removing the SD card. I am using the standard example sketches within. Only altering the 2 lines of code for use with the audio board. However when trying to write files to the flash chip from SD card, I get failures still...

Woops, I typed that wrong. It is a W25Q128FV - as per the attached image above. Verified visually as well. This chip IS in your list of tested chips. Thanks!

Still NOT able to flash the Winbond W25Q256FV chip using the included Teensy SerialFlash library. This is a chip I purchased from Digikey and one that has been working prior. Initially was using Frank's flashing library. But since the upgrade, I figured Id give it go a while back. Still the...

Thats a nice precision! Thank you!

Thank you Paul! So what sort of precision is there in the measurement that is output from them? I know it goes from 0 to 1. But is that for example, 0.001 . As in 1/1000th? Thanks!

Im curious, at what bit resolution do the PEAK and FFT functions operate at? Is it at the standard 10bit resolution? I know the output from PEAK and FFT are from 0 to 1. To what decimal place will these measure down to? For example, doing an analog read on a pin, is by default set to 10bit...

Thank you very much! By "buggy", I didnt mean to insult the cleanliness of the code within your and every one elses work. Just meant getting my setup to work with the new versions has not been without incident. I couldnt really find any documentation or info on the fact that the SPI.begin had...

Sorry for the poor example. I have upgraded to Arduino IDE 1.6.6 and Teensyduino 1.26 Have updated all the libraries to their current versions. When running the code below, which I have stripped out all of the FFT code, to simplify things, it fails to produce any output to the line out. I...

WMXZ, Could you please explain that in a little more detail as it would pertain to my code please? Im not sure why I would need transactions, as the only device that Im aware of using the SPI is my digipot. Unless there is some hidden SPI action going on with the audio board to operate...

Any insight into this issue would be greatly appreciated. Thank you in advance!

Well when I combine the two to also include audio output, it fails now! As long as I dont try to set the digipot and comment out the SPI lines of code, the audio comes out ok and the FFT works as well. Please help NOTE: Using 96mhz setting with Arduino IDE 1.6.5 - teensyduino 1.24 // FFT...

That worked! Why would the #include <SerialFlash.h> have to be in there though for a straight pass through?

Thanks Paul! I will investigate. Thank you so much for the help!

Thank you for the detail. I have updated to the latest teensyduino 1.26 and Arduino 1.6.6. Using the latest audio lib included with the software upgrade. And using the example sketches. Producing sound with it, such as a sine wave and out works fine. But once I try to bring sound in from...

Does any one have any feedback on this issue? Thank you!

I did copy and paste the code you shared previously into a new sketch. And it DID work. However, what does that do for the code I am trying to run that I posted? I ran your code example exactly as shown in the thread you shared. Running on Arduino IDE 1.6.5 and teensyduino 1.24 . It works...

The code you shared, does work on my system. Im not sure what you mean by.. "That linked code shows waiting for the Serial to come on line - so your output may just be lost before the serial monitor shows up." I appreciate your help.

I have tested a Teensy 3.1 with an audio board attached with the following included sketch. /* Mono Peak Meter Scrolling peak audio level meter in the Arduino Serial Monitor Audio input needs to connect to pin 16 (A2). The signal range is 0 to 1.2V. See the documentation in the...

My apologies. I found my error. Thats why its bad to code late at night without sleep. lol I left out the: pinMode (dpotCS, OUTPUT); SPI.begin(); And so it cause things to stop. All good now. So far.

Sorry, I forgot to post the code. Here it is. #include <Audio.h> #include <Wire.h> #include <SPI.h> #include <SD.h> const int myInput = AUDIO_INPUT_LINEIN; AudioInputAnalog audioInput; AudioAnalyzeFFT1024 myFFT; AudioOutputI2S audioOutput...

I have a Teensy 3.1 (not the latest teensy duino version or arduino IDE) Running 1.0.6. It is connected to an audio board. I have successfully gotten the FFT to analyze my incoming analog signal coming from my own made preamp. The preamp has a digipot on it that I control via the Teensy. I...

So you dont feel it could be from the flux itself that has possibly caused the short?

I have soldered many Teeny 3.1s and Audio Boards (shields) together. As well as soldered many flash chips to the Audio Board. I have had one in particular for approx. 1 year running as my test board. Until recently, the board was operating just fine. It has since stopped producing audio...

Having the same issue. The audio board was working before. And now it just randomly quit sending any audio out. This is the second board I have had quit unexpectedly.

Im repeating my previous post in case you all missed it. "Could some one please send me a couple of the WAVs they are using that they have converted successfully via SOX or Audacity? I want to try and convert them on my end and see what happens. Thank you! " Thanks!

Could some one please send me a couple of the WAVs they are using that they have converted successfully via SOX or Audacity? I want to try and convert them on my end and see what happens. Thank you!

It works when using Franks WAV to RAW program, but not the other ways to convert.. SOX or Audacity.

Indeed I am using the audio board. And did make sure the SCK and MOSI lines were uncommented.

I did use the erase all INO. Several times in fact. Still receive the same results.

I have confirmed that it is NOT the chip. I have flashed the chip once again with a RAW file made from Franks converting application. And it works. But sounds a little dirty. Also the file size on this one is about half of the other RAWs when converted via SOX or Audacity.

I just got this output when I ran the Raw SerialFlash Hardware Test Raw SerialFlash Hardware Test Read Chip Identification: JEDEC ID: EF 40 18 Part Nummber: W25Q128FV Memory Size: 16777216 bytes Block Size: 65536 bytes Reading Chip... Writing 7758 signatures error writing...

I just tried the SOX suggestion as posted earlier. Did not work. Produces the same results. I am at a loss as to why converting them via Franks tool works, but the others do not.

Thanks for the step by step. That is exactly what I have done the first time. The track appears as one single wav in mono and 44.1. I will give it a go once again. Will also try the SOX route to see what happens. Thanks again!

Im not asking for a step by step example with screen shots and the like. Just a simple , "what did you do in Audacity" to get your samples converted type of explination. Here is all my code for playing said flashed samples: #include <Audio.h> #include <Wire.h> #include <SPI.h> #include...

I remove the .RAW parts from the names as it isnt needed.

mxxx Im very calm. No use of caps or exclamation points or sarcasm used. And I already did format my question properly as you pointed out. I tried using Audacity. I exported the 44.1K , mono, 16bit WAV to RAW header-less, Signed 16bit PCM. And the playback is completely jumbled and...
