    Thanks for the ideas. That sounds like a good solution. Also it is not critical that I not lose data, just a user experience consideration.
  2. So this is for a eurorack module. Meaning that it...

    So this is for a eurorack module. Meaning that it gets +-12v into the module. I then use a 5v linear regulator to power the teensy. I basically can't expect to access the state of the power anywhere...
  3. Writing to flash or sd card on power loss

    I am working on a project with the teensy 4.1 that I want to be able to detect a loss of power and save some things to flash or the sd card. I am looking at this circuit that provides a capacitor for...
  4. It is likely that in the end it will be perfectly...

    It is likely that in the end it will be perfectly fine to use 16bit ints. My prototype uses ints and the recording buffers are long enough and high resolution enough for me to not run to the end of...
  5. Can I use a 10 bit data type for ADC storage?

    I have a project where I am recording the value of an analog input, Ideally the recording buffer would be as long as possible. Since the max reliable precision of the ADCs is 10 bit the extra 6 bits...
  6. Questions about dc coupled audio input to teensy 4.0/4.1.

    I am working on integrating the teensy with my modular synth. I have gotten traditional -5v to +5v CV input working well with the analog inputs, and have a simple sketch that records the input and...
  7. I haven't tried connecting it to a pitch CV, and...

    I haven't tried connecting it to a pitch CV, and I don't have an oscilloscope, but the input is certainly stable enough to prototype ideas with. I find the input to drift +-4 values of the 12 bit...
  8. Teensy CV input and output for eurorack modular synths.

    So I have been working on getting the teensy interfaced with my modular synthesizer and made a video on the circuits that I used in this instance. There is so much fun to be had making your own...
  9. That makes a lot of sense. I have tried your...

    That makes a lot of sense. I have tried your suggestion and am still not having any luck. here is my modified code, which still works for arduino uno, but not for teensy. Thanks a ton for the help....
  10. Using a DAC(mcp4821) with teensy that I have tested with an arduino uno.

    I am trying to get a dac working with the teensy 4.0 I have. I was successful getting it to work on an arduino uno, but it does not work on the teensy. I noticed in the documentation for spi that...
