Details about Daisy Patch Knobs and hardware

[StaffanMelin]

@algoritmarte

Hi,
I just bought a Daisy Patch and I’m trying to write some code.

Hi and welcome to the forum!

@algoritmarte

Where can I find some documentation about the details of how the hardware is “exposed” (in the DaisyPatch object).

Well, the docs are not that great, but there are a lot of answers to be found in the forum – or just ask, as you just did!

@algoritmarte

1. what is the range of values returned by GetKnobValue() ?

I don’t own a Patch, only Seeds. but I would guess 0-1. But you can use the Logger class to print out what you get back: Using the Logger class - #3 by StaffanMelin.

@algoritmarte

2. how the Control inputs affect the knob values ? (are they independent?)

Added, answered here: Daisy Patch Input CV voltage and Control Knobs

@algoritmarte

3. what is the effect of calling ProcessDigital/AnalogControls ?

Sorry, don’t know. Something I haven’t used.

@algoritmarte

4. what is the difference between the main thread and the AudioCallback process ?

As the ACB returns numbers for the CODEC/audio output, it must finish in time for the next block. The main thread is interrupted if the MCU needs to process audio data.

See discussion here: Programming paradigm: callback vs main - #5 by StaffanMelin

@algoritmarte

5. what is the best way to handle audio / control voltages / display / midi ? (e.g. is it ok to handle the display in the audio callback, or is it better to handle it in the main?)

See above!

@algoritmarte

6. what are the range of values that can be assigend to CV / audio outputs and gates ?

Usually -1 to 1 (float), but I am not sure about the Patch, sorry.

@algoritmarte

I gave a look at the examples, but it’s not so easy to “reverse egineer” the information, and the library documentation doesn’t provide enough details.

You are right. The examples are sweet but short. Check out some other projects in the Projects and examples category, and browse around in the forum. And keep asking!

I hope this is at least of some help to you!

Happy coding!
