PDa is a Pd clone for PDAs.
So with this port you can run Pd on your caanoo.
All needed files are downloadable on OpenHandhelds.org
Here is a copy of the included readme:
pdnoo a PDa port for caanoo pdnoo is composed by two softwares: 1. PDa (Pure Data Anywhere) 2. A 'proof of concept' frontend written in Bennu PDa was compiled with the official GPH toolchain, using a modified makefile (included into this distrubution) and without graphical support. I added these lines to PDa makefile: ====================line40===================== # CAANOO toolchain ifeq ($(CC), arm-gph-linux-gnueabi-gcc) pd_LDFLAGS += -elf2flt -static -static-libgcc pd_LIBS = -lm -lpthread pd_DEFINES += -D__linux__ -Dfork=getpid extra_DEFINES += -D__linux__ -Dfork=getpid endif ====================line128==================== caanoo: make pd_SRC="$(pd_SRC) $(extra_SRC)" DEFINES="-DPD -DUNIX -DSTATIC" CC="arm-gph-linux-gnueabi-gcc"\ pd pd-watchdog $(BIN_DIR)/pdsend \ $(BIN_DIR)/pdreceive I also had to delete all esd related stuff. To make PDa useful, you need some kind of frontend which have to speak with pd in some way. If you put a [netreceive] object into your pd-patch, you can send TCP packets to pd. This packets must follow the FUDI protocol, that can be easily implemented into you custom code if you wish. A more simple approach is to call 'pdsend' executable (included) that will make the job for you ('pdreceive' is also included). You can write a frontend in your favourite language, I made one with Bennu, because its caanoo support is good and it is a very simple language. You can read the source of my code by opening 'pdnoo.prg' with your favourite editor. 'pdnoo.gpe' is a simple script that starts pd, compiles and starts the bennu application. To make everything work you have to install the bennu-runtime by coping 'bgd-runtime' directory into the same directory where 'pdnoo' directory and 'pdnoo.gpe' file are. If you whish to install the runtime somewhere else, please edit the PATH lines of 'pdnoo.gpe' properly. Please condider my example frontend as 'proof of concept', its work is to read touchscreen's coordinates and to send them to pd through 'pdsend'. It is not perfect and right now to stop it you need to reset your caanoo. If you are interested in updates or other things related to pdnoo please visit my blog, where I will put my future improvements. http://elettrofonesi.blogspot.com If you are interested in the source code of PDa go here: http://pd-anywhere.sourceforge.net To read about and download Bennu go here: http://www.bennugd.org You can find the same GPH toolchain I used here: http://git.fungp.com If you do not have a caanoo but a gp2x here you can find a very similar thing that actually inspired me: http://mccormick.cx/projects/gp2xPd/ If you do not know Pd, please visit this page: http://puredata.info To learn more about FUDI protocol: http://wiki.puredata.info/en/FUDI I hope that this piece of software can be useful to musical experimenters or to game developers who want to implement more dynamic sounds than a static collection of waves. Have fun with pdnoo, and please share your patch/code!
