Hi Alain,
wouldn't it be a lot easier to take the system that you already have and
use OSC or FIDO to send the values (that you were printing) to PD
for further processing?
I am greatly in favour of using different systems for different jobs
and letting
a protocol like OSC or fido (netsend) connect them together.
I could easily help you with that problem, if the code is running
already.
Cheers,
tim
