heavy compile pd patch in C code.
you can then compile this C code to whatever architecture/platform you wish.

cheers

Apropos of the heavy compiler, I was reading up on it and simply moved on because of what seems to me a lack of information. There was an allusion to it working for a wide variety of platforms and so on, but no actual lists of this supposedly wide variety.
Does someone have an idea if it could compile Pd patches to work without an OS for some architecture? Otherwise, why would you bother with it? (that's not a rhetorical question)
Thanks.

    hello,

    I recently send a mail in this list describing my experience of audio synthesis on microcontroler, but i did not use libpd.

    i did not recommend libpd for microcontrolers.

    in fact, I did not recommend audio processing on hardware that did not have support for float arithmetic.
    (only me or crazy nerd do that).

    a micro controller to use is for example the cortex M4. You  can find them on the teensy hardware.
    teensy also provide a audio synthesis library, and is supported by arduino IDE.

    You can also have a look at the heavy compiler if you want to embedded a pd patch.

        Hi,

        has anyone experience in using LibPd on a microcontroller?
        I wanna try to run some rather basic DSP code on this guy here:
        https://www.olimex.com/Products/IoT/MOD-WIFI-ESP8266-DEV/open-source-hardware
        There are some existing Arduino/C++ frameworks and I thought I could either write my own small DSP library in C++ or use LibPd.

        I understood that LibPd is completely independed of audio drivers and external libraries and since it's plain C code it should work on everything that can run code. However, I have only encountered LibPd in the context of other applications (processing, openFrameworks) and mobile devices so far. Do you think it could work on an ESP8266? I'm also a bit concerned about efficiency, as computation power is rather limited:

        "ESP8266EX is embedded with Tensilica L106 32-bit micro controller (MCU), which features extra low
        power  consumption  and  16-bit  RSIC. The  CPU  clock  speed  is  80MHz.  It  can  also  reach  a  maximum
        value  of  160MHz.  Real  Time  Operation  System  (RTOS)  is  enabled.  Currently,  only  20%  of  MIPS  has
        been  occupied  by  the  WiFi  stack,  the  rest  can  all  be  used  for  user  application  programming  and
        development."

        Christof
