  1. You can't convert a square wave to triangle over...

    You can't convert a square wave to triangle over a ten octave range using a simple integrator

    The integrator only needs to track 2 octaves of pitch bend plus one octave of semitone offset...
  2. It will not have as many knobs as you think, only...

    It will not have as many knobs as you think, only the pitch bend will have per note control. Everything else will have one global control per effect.

    Each note will need 2 square waves, one phase...
  3. That is all very helpful, apart from the fact...

    That is all very helpful, apart from the fact that I need all my notes out on separate pins. The idea is to used the Teensy as an accurate pitch source in a mostly analog synthesiser. There will be a...
  4. The individual Teensy boards don't need to know...

    The individual Teensy boards don't need to know what is happening on the other Teensy boards.

    Someone else was telling me to use a multiplexer instead is I2C.

    He also said I could use 1...
  5. Advice on connecting multiple analog inputs to multiple Teensy4s via I2C

    I am designing a polyphonic synthesizer that will generate 88 notes in parallel from multiple Teensy4s. Each note will have a separate pitch bend input via a slider potentiometer. In order to reduce...
  6. I should have mentioned the square waves are...

    I should have mentioned the square waves are audio pitches. I don't see why they is an issue sharing PWM frequencies as they are not the same as the audio frequency. The PWM is like a high frequency...
  7. Which part of my question are you referring to?...

    Which part of my question are you referring to? Having 31 outputs or the PWM part?
  8. Is it possible to use all 31 PWM outs for 50/50...

    Is it possible to use all 31 PWM outs for 50/50 duty cycle square waves without PWM?
  9. How to use digital outs as a square wave generators?

    I am designing a music synthesizer that will need multiple square wave outputs at different frequencies from multiple Teensy4/4.1. As I need a maximum number of outputs I thought about using digits...
  10. Where is the list of pin names for Teensy4 for digital I/O ?

    On this page https://www.pjrc.com/teensy/td_digital.html there is a list of pin names for the digital read and write, but not for Teensy4. I am trying to use pin 10 as a digital out using...

    Ahh, 0-255 is only for 8 bit resolution. I see it's possible to change the number of bits for this from 1-32 by using analogWriteResolution()
  12. Thanks I would never have thought of using bit...

    Thanks I would never have thought of using bit shit. I though that the output for analogWrite had to be between 0-255.
  13. I have a loop to ramp the pulse width from 0% to...

    I have a loop to ramp the pulse width from 0% to 100% at 12 bit resolution. Is it possible to avoid the divide by 16 within the loop to save processor time. I tried to increment the loop by a fixed...
  14. How do you find detailed info about the Teeny4?...

    How do you find detailed info about the Teeny4? There is not much online. Would I have to go to the ARM M7 data sheet?
  15. So if I want the highest frequency for 8 bit...

    So if I want the highest frequency for 8 bit resolution, I should use 150MHz/256 ?
  16. It can go very fast I just took it up to 10MHz, I...

    It can go very fast I just took it up to 10MHz, I bet the resolution is bad taking it that high though.
  17. Thank you, I just found the answer here...

    Thank you, I just found the answer here https://www.pjrc.com/teensy/td_pulse.html
    I am new to this forum, I can't find out how to delete this post. Maybe it is helpful to other newbies.
  18. Is it possible to change the PWM frequency for the analog output pins on a Teensy4?

    I am planning to make a 3 phase motor driver on a Teensy4. I measured the PWM frequency with a scope. It was about 7kHz. Normally in motor drivers use upwards 10kHz. The Teensy4 will be in the motor...
