[PD] Pduino and arudino mini pro/raspi debian- Pduino or Comport?

[Pagano, Patrick]

I have done all of that for use with the ardunio uno, it's when the raspi2 is directly connected to the serial pins that it does not connect. 
I tested the device on mac and used the ALLINPUTS firmata and it works with a virtual serial created by FTDI
just can't seem to talk to it with Linux debian running vanilla

comport works fine with the UNO

mknod? this sounds like you are following advice from the 1990s.
these days mknod is hardly ever needed: instead any devicefiles will be
created on the fly by the resp. drivers.

a little bit of googling hints that /dev/ttyAMA0 is indeed the name for
the serial interface on the GPIO ports - which afaiu is what you want.

so you just use that device.


then you need to get the permissions correct.
check whether the device is already setup to allow group-members to
write to it, and which group that is:
$ ls -l /dev/ttyAMA0
crw-rw---- 1 root dialout 4, 67 Sep  3 16:12 /dev/ttyAMA0

and eventually add the user running Pd to that group:
pd at raspbian $ sudo bash
root at raspbian # adduser pd dialout

after that you only need to re-login as that user to let the new group
membership have any effect.
