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

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. -Chuckk

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. Cyrille Le 09/05/2016 17:01, Christof Ressi a écrit : 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."
