Yeah, I struggle with that too, its just not a very elegant implementation.

It might help thinking about what happens under the hood, to better conceptualize it:

- All audio signals are 16 bit...

Hi Everyone

With some colleagues I'm working on a haptic feedback application. We're using the audio library to generate the control signals of the haptic actuators. We're running into bugs that...

Hi Everyone

Me and colleagues were having problems with reading analog signals on the teensy 3.5. There seemed to be a 'jump' around the mid-way point, if moving from 0 to ~512, the value would...

So 1 page stores 16 times 3 floats + 1 uint32.

So I if I wanted to store 32 uint16, I would need 64 bytes, so I could have a page consisting of 4x64. (OK, I do really just need to play around with...

OK, I was thinking about it incorrectly. I just assumed that the array index of the 'page' variable was referring to the data-frame (or to what you refer to as "page"). I initially didn't quite...

Hi Manitou

I tested your code and I am getting behavior that I don't understand.

I modified what you sent me a bit, to better understand whats going on:


#if 1
pages_written = 0;

Cool. I will check this out later tonight. Thanks for all your help.

@manitou

Sadly I am so spoiled by Arduino and Processing that I struggle with 'regular' C. If you could show me, in code, how you would use the struct that you wrote in your previous post, it...

Thanks manitou. I will play with your example. What I need to do will be a little bit more involved, but if I can figure out what you're suggesting, that should help, cause the logging will be...

Reporting back: Yes, you *can*, but its apparently not a good idea.

Setting the file limit to 60k (which is what I had in mind) grinds to a halt (individual files take multiple seconds to write)....

Thanks for your answer and apologies for cross-posting.

Is there a way to check how much space is being allocated for file-names?

Would be great if PaulStoffregen could weigh in on this. I can probably change things around to stay within the file limits, but that would make some other aspects of the project more complex.

Hi Everyone

Project using prop shield + teensy 3.2 + SerialFlash Library

I'm trying to write a program that logs data to Flash. I need it to run for ~ 2 hours, I am planning to adjust my...

I've been just playing with some of the example code provided here: https://learn.sparkfun.com/tutorials/teensyview-hookup-guide

If you scroll down you will find a section about interfacing the...

OK, so I am slowly learning how to use this...

As I had trouble finding a file that would help me get started (the examples provided are all too complex for me) I created one.

I assume it would...

Hi Everyone

I only have very basic programming skills, but would like to do the following:

- When the teensy is turned on, it collects some data (for example from the analog input).
- At...
