I am trying to use [disis_spi] on my raspberry pi (Linux raspberrypi 3.6.11+ #538 PREEMPT Fri Aug 30 20:42:08 BST 2013 armv6l GNU/Linux ) with Pd 0.45.2. When I open the help patch 'disis_spi-help.pd' and click on [open /dev/spidev0.0(, in Pd console i get : could not open SPI device.
I used to use a C++ program until now with which I used to open "/dev/spidev0.0" and all was OK.
What can I do to solve this problem ?
Hi,
I haven't tried the external with pd-vanilla, although there is no reason I can think of that it would not work with vanilla. Did you make sure to load the necessary drivers (I assume you did since you mentioned you used to access it before via a different application, but if you loaded them manually and have rebooted RPi since, they would not be necessarily loaded this time around). Just to be sure try:
lsmod | grep spi
...and see if it lists spi-bcm2708, if not, do:
I get : spidev 5248 0 spi_bcm2708 4841 0
sudo modprobe spi-bcm2708 sudo modprobe i2c-bcm2708
If that works, you may want to add those at the bottom of your /etc/modules config file (one module per line, like so):
spi-bcm2708 i2c-bcm2708
So I guess I needn't to add these lines ?
This will ensure they get loaded every time you start the RPi.
BTW, which gen RPi do you have?
Model B.
What I do to have disis_spi.pd_linux is : $ cd pd-l2ork_rpi $ ./makeall.sh
But I get several errors :

And after : $ pd disis_spi/disis_spi-help.pd If i click on [open /dev/spidev0.0( I get : could not open SPI device
Something else i can do ? Thanx for you help. ++
