you can then compile this C code to whatever architecture/platform you wish.<br>

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.<br>
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)<br>
Thanks.<br>

hello,<br>
<br>
I recently send a mail in this list describing my experience of audio synthesis on microcontroler, but i did not use libpd.<br>
<br>
i did not recommend libpd for microcontrolers.<br>
<br>
in fact, I did not recommend audio processing on hardware that did not have support for float arithmetic.<br>
(only me or crazy nerd do that).<br>
<br>
a micro controller to use is for example the cortex M4. You can find them on the teensy hardware.<br>
teensy also provide a audio synthesis library, and is supported by arduino IDE.<br>
<br>
You can also have a look at the heavy compiler if you want to embedded a pd patch.<br>

Hi,<br>
<br>
has anyone experience in using LibPd on a microcontroller?<br>
I wanna try to run some rather basic DSP code on this guy here:<br>
<a href="https://www.olimex.com/Products/IoT/MOD-WIFI-ESP8266-DEV/open-source-hardware" rel="noreferrer" target="_blank">https://www.olimex.com/Products/IoT/MOD-WIFI-ESP8266-DEV/open-source-hardware</a><br>
There are some existing Arduino/C++ frameworks and I thought I could either write my own small DSP library in C++ or use LibPd.<br>
<br>
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:<br>
<br>
"ESP8266EX is embedded with Tensilica L106 32-bit micro controller (MCU), which features extra low<br>
power consumption and 16-bit RSIC. The CPU clock speed is 80MHz. It can also reach a maximum<br>
value of 160MHz. Real Time Operation System (RTOS) is enabled. Currently, only 20% of MIPS has<br>
been occupied by the WiFi stack, the rest can all be used for user application programming and<br>
development."<br>
