[PD] [PD-announce] issiconvert
Hi all, Just a short announce of the release of `issiconvert', a pd library which does some simple conversions between integers and symbols: [int2shex] convert (int) float to symbol of a hexadecimal value with `0x' prefix [int2sdec] convert (int) float to symbol of a decimal value with `0i' prefix [int2soct] convert (int) float to symbol of an octal value with `0o' prefix [int2sbin] convert (int) float to symbol of a binary value with `0b' prefix [sany2int] convert a symbol of any of the four types (with prefix) to (float) int [symbol2clist] output a list of floats for the corresponding character values of a symbol [strlen] calculate number of characters in a symbol [symbol2symbol] output the input if symbol $ git clone git://git.code.sf.net/p/pd-issiconvert/code issiconvert https://sourceforge.net/projects/pd-issiconvert/files/latest/download?source=navbar Comments are welcome at the project page, my personal mail address or pd-list.

[PD] Forwarding serial data through an Arduino (with firmata) to a serial display
Hi everybody! I am dealing with the problem that I have changed to a new mainboard which doesn't have a serial port anymore. I'm on Ubuntu Natty. I used to send LCD display data to my remote on the normal serial port using [comport]. The display itself has a serial interface. The remote uses a separate cable and [comport] for USB going to the arduino. Is it possible to transfer the serial data for the display through the arduino using the arduinos serial out to feed the display (with a baud rate of 19200) ? I still need to use firmata for all other arduino stuff. So it should be like an addon to firmata. Or is this already possible with the current firmata? If anybody has done this before I'd appreciate any help! Ingo ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

[PD] Raspberry Pi USB2 audio fixed (apparently)
Hey all, So, umm, yeah. Is everyone on this already? Just got a message saying that an 'rpi-update' should fix the usb2 problems for soundcards. Not checked 'cos I spent bloody ages tracking down soundcards that did work. Good to know though. http://www.raspberrypi.org/phpBB3/viewtopic.php?p=364163sid=04807df00bff9fa076fd62c358dfd9fc#p364163 http://www.raspberrypi.org/phpBB3/viewtopic.php?p=362690#p362690 http://www.raspyfi.com/raspberry-pi-usb-audio-fix/ (anyone checked out this distro btw?) Good to hear there seems to be lots of audio tweaks and exploration going on on the Pi (still:) Best wishes, Julian ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

Re: [PD] Forwarding serial data through an Arduino (with firmata) to a serial display
Thanks! I'll have a look at the SoftwareSerial library. You also need a TTL-to-RS232C voltage converter between the Arduino and display. The serial converter of the display takes already care of that. It is probably much simpler to use a separate USB to serial adapter. Those work out of the box with Ubuntu and you only have to change the serial port name in your patch. Yes, that works fine but it mixes up the port number of the arduino and the serial adapter. I can't get the two to be assigned to the same port number each time Pd starts. They both show up as /dev/ttyUSB0 or /dev/ttyUSB1 on the [comport]. It also would be cleaner with less cables to have the arduino taking care of the serial data transfer. If I can't get that to work I'll have to use a serial adapter and find a good way to distinguish the two automatically.

Re: [PD] Forwarding serial data through an Arduino (with firmata) to a serial display
As you're on Linux, the port number assignment is probably tagged to the specific usb bus port and ca change. You can have them assigned to the same serial port # each time if you create a little udev rule for both the arduino and the serial port adapter and specify what you want them to be or create a symlink to say /dev/ttyArduino /dev/ttyLCD ...

They both show up as /dev/ttyUSB0 or /dev/ttyUSB1 on the [comport]. There are some udev rules floating on the net for that. You can also use the files in /dev/serial/by-id/ instead of /dev/ttyUSB* and select by serial number. hth, -- Charles ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
[PD] Puredata external for websocket communication.
Hi. I started working on a pd external that allows communication with a web browser using websockets. My use case is developing a GUI in html/javascript and sending messages to pd-extended using the websockets javascript API, no proxy or other scripts needed, just my external. You can take a look at it herehttps://github.com/dancing-skeleton/dancing-skeleton/tree/master/pd/externals/src/websocket_server. There's an example patch and html file that explains how to use it. Feedback is welcome :) Where is the central place for this sort of thing? I'll move this to it's own repository and post it there in the next few days.

We managed to confirm both sensors are working via pin11 from the IC going between earth 3v with gpio17 disconnected and running i2cdetect. That was really useful as it was the first definite confirmation that both sensors are working correctly. In the process of doing that we also discovered that the line from gpio17 to IC pin11 was in fact not connected to gpio17 at all! To try and keep the protoplate reasonably tidy we'd soldered to the underneath of the plate. Somehow in the flipping from one side to the other we'd messed up and missed by two connecting it to ground and therefore making complete sense as to why only one sensor was working. This is also after spending a half hour this morning checking and double checking all the various lines and connections. So working now - blimey. OAN - Whilst wanting to progress the Pd patch last night, having left it since last Friday, I plugged the box with all our gubbins in and promptly blew up the Pi - proper fried it it seems. Loose power cable to the Pi and we think it was touching a screw on the box. Kapput. The RPi was a rev1 board and my other is rev2 and the custom image I made doesn't work on the rev2 board. Always know this was a possible issue but, you know, got a ton of other stuff to be getting on with. So spent until 4am building a fresh image from http://moebiuslinux.sourceforge.net/ and works really well so far-which is good. Didn't get my patching done though:) Long way of saying that I've updated my C file to reflect this and all working lovely. Thank you thank you thank you. Been much fun, Julian P.S.
