Re: [PD] Arduino/Raspberry comport issue
baud rate _should_ be the same in your arduino code and in your comport object, otherwise you get messed up characters. i dont have rpi here, but i didnt noticed any chenges between running comport on rpi, or standard pc. when you send [devices( you usually get list of connected serial devices - arduinos with usb2serial and com ports if you have. also check, ig your user is in uucp group, i think it is necessary, and maybe also dialout group can be important. probably it depense if you are using debian fedora or arch on this rpi kub On 11.11.2013 18:13, Alexandros Drymonitis wrote: Are you sure the baud rate you set to [comport] is the same as the code you load on your Arduino?

Re: [PD] Arduino/Raspberry comport issue
If I didn't mention I'm actually using a Teensy 3.0 not an arduino. Read on pjrc.comhttp://pjrc.com that the teensy runs at full USB speed all the time unlike arduino. So that seems like the comport speed should be irrelevant? In any case yesterday I turned the rip and teensy on and pd was reading from it immediately every time I opened a patch. Maybe it worked itself out? I'm using ccrma satellite which is a raspbian distro. I'll check the user permissions also On Nov 12, 2013, at 2:38 AM, kubriel kubr...@servus.atmailto:kubr...@servus.at wrote: baud rate _should_ be the same in your arduino code and in your comport object, otherwise you get messed up characters. i dont have rpi here, but i didnt noticed any chenges between running comport on rpi, or standard pc. when you send [devices( you usually get list of connected serial devices - arduinos with usb2serial and com ports if you have. also check, ig your user is in uucp group, i think it is necessary, and maybe also dialout group can be important. probably it depense if you are using debian fedora or arch on this rpi kub On 11.11.2013 18:13, Alexandros Drymonitis wrote: Are you sure the baud rate you set to [comport] is the same as the code you load on your Arduino?

Hi, Allen, Michael wrote: I’m using a Teensy to get data from Pots and switches into PD on a RPi. The teensy sketch is set to open serial at 9600 baud. In PD I have [comport devicename 9600].

I’m specifying the device name since it seems to be switching between port 1 and 0 for unknown reasons upon power cycling or unplugging, etc. for the device name you can use the [devicename ( message instead with port name rather than a port number. Then use it like that: [loadbang] | [devicename /dev/serial/by-id/the-id-of-you-teensy, baud 9600 ( | [comport] This may solve the other problem. ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

[PD] Arduino/Raspberry comport issue
I’m using a Teensy to get data from Pots and switches into PD on a RPi. The teensy sketch is set to open serial at 9600 baud. In PD I have [comport devicename 9600]. It won’t receive data. When I change the object to [comport devicename 115200] it immediately opens and starts receiving data. I’m specifying the device name since it seems to be switching between port 1 and 0 for unknown reasons upon power cycling or unplugging, etc. So then if I save the patch with [comport device name 115200] and reopen it, it won’t receive data. If I change the object to [comport device name 9600] it immediately opens the port and starts receiving. So it doesn’t seem to matter what the absolute value of the baud rate is, it just wants to be something other than what I specify initially? Ultimately I want to run headless without a gui, and just plug the RPi in and have it work so needing to change the object each time will not fly. Any ideas on what is happening here?
