no [serial] in pd. use one of the PD installers: at.or.at/hans/ "software" -> "pd" -> "installers" should have the right [comport] with working help.. I hope. b.

What PD are you using? can you create a [comport] object? Try right clicking to get the help for [comport] to set the parity, flow control etc, and also the devicename. the message pp2500 would then be created with a stream of decimal bytes like: 112, 112, 50, 53, 48, 48 "112" is the byte that incodes "p" in ascii you may need a "return" at the end: 112, 112, 50, 53, 48, 48, 10 if you put the above in a message box and send it to the unit through the comport object you should be in business. I don't have any ASCII encoding table here, so I used the pd "key" object, which I'm not sure is correct... b.

Keyspan serial control
by Jasper van den Brink 31 Aug '05

31 Aug '05

Hello all, I am new to pd and dont have any experience with pd to, i am learning. What i am trying to make is a controller for a rs-232 pan/tilt unit. I managed to give commands with zterm and it works fine. Command like pp2500 will set the pan movement to step 2500 for example. First thing i want to try is to give commands like that with Pd. The settings for the pan/tilt unit are: The host terminal or computer should be set to 9600 baud, 1 start bit, 8 data bits, 1 stop bit, and no parity. Hardware handshaking and XON/XOFF are not used. Using OSX 10.3.9 The keyspan serial adaptor is: USA19QW181P1.] I have been looking everywhere to see if i could find an example howto just give simple commands to the pan/tilt unit but i cant find it anywhere. Would somebody be able to send me a Pd patch for it? Thanks a lot, cheers jasper

0.39-test6 ALSA audio broken?
by Claude Heiland-Allen 29 Aug '05

29 Aug '05

Hi Miller, and others, With ALSA audio output I get: tried but couldn't sync A/D/A ^^^ repeated many times audio I/O error history: seconds ago error type 3.00 A/D/A sync 3.00 DAC blocked 3.00 A/D/A sync 3.00 DAC blocked 3.00 A/D/A sync 3.00 DAC blocked 3.00 A/D/A sync 6.92 DAC blocked 6.92 A/D/A sync 6.92 DAC blocked 6.92 A/D/A sync 7.09 DAC blocked 7.09 A/D/A sync 7.09 DAC blocked 7.09 A/D/A sync 7.09 DAC blocked 7.09 A/D/A sync 7.09 DAC blocked 7.09 A/D/A sync 7.44 DAC blocked I set the buffer size to as high as 500ms and still got >100ms audio dropouts every few seconds, which is obviously no good at all. PortAudio with /dev/dsp works fine with the same settings, no dropouts at all, so I guess that's what I'll use for now. I have yet to try JACK, and OSS didn't work at all (no devices to choose from, which is strange because PortAudio works fine with /dev/dsp) Claude

SCons under MinGW, and Building PD from Source
by Matthew Allen 28 Aug '05

28 Aug '05

After about a year absence I am trying to get back into PD land. My current setup is a winXP machine, but I had gotten used to being able to make small changes to how things worked in PD under Linux. I would like to be able to do some of the same things under windows, along with starting to contribute again to the PD community. My day job give me access to VC 7.0 but it appears that no one in PD-Dev land is using this to build PD? All web and list resources seem to point to using MinGW for building. Since this was the most documented route I went this direction. After following http://puredata.org/docs/developer/mingw I had a working msys and mingw system. I already had python 2.4 installed, but have no experience with SCons. I think this is where I am failing, as I am quite sure I should be editing some SCons file somewhere to match my system. I am calling SCons on the pd dir like this: $ python /mingw/bin/scons install scons: Reading SConscript files ... Checking for sin() in C library m... no can't find Math library Its dying on line 148 on the pd/src/SConscript. So what have I borked in my MinGW setup? Also, if you have gotten this far, Is anyone building PD with VC 7? Not just externals (which I can get to build, with an existing install of PD) but all of PD land? If someone does and is willing would you mind putting your project file into the devel branch in CVS, I am sure a great many folks would appreciate the jumping off point. Matt
