We’ve released new versions of pisound-btn, kernel module and firmware for the pisound beta boards!
In a nutshell, we have improved the visual feedback of using the button to load puredata patches, added 16 bit sample format support and made it compatible with the volumealsa widget.
single_click.sh script will attempt to mount any attached USB device as well as search for main.pd first in the attached media, then, if not yet found, in /usr/local/etc/pisound-patches/ in the sdcard.
double_click.sh script will kill all puredata instances and unmount the attached USB devices.
hold.sh script will still safely shutdown the device.
down.sh script was added for completeness, for your customization.
up.sh script was also added for completeness, for your customization.
Better visual feedback using the MIDI activity LEDs added:
After every click, the LEDs should flash.
In case of single_click.sh success, the LEDs should flash three times after puredata got started (can take a few seconds).
In case the patch was not found after single_click, one long flash should be displayed (firmware update for beta pisound boards is required).
After double_click.sh finishes unmounting attached media, it will flash with moderate duration for 2 times.
After hold.sh, the LED will flash 10 times quickly.
More info:
Kernel module changes:
Added /sys/kernel/pisound/led sysfs object for allowing scripts to flash MIDI LEDs for variable durations, firmware was accordingly.
Added compatibility with 16 bit sample formats.
Fixed generic bcm2835-i2s driver to allow asymmetric sample formats.
Added compatibility with volumealsa raspbian widget, so pisound can be set as default output card through it.
Hi,
I’ve just installed the new firmare and everything goes fine apart a dependencie problem with the customize avrdude installation (from a clean raspbian pixel ) : N: Is the package apt-transport-https installed?
just sudo apt-get install apt-transport-https
resolved my problem.
Interesting, thanks for sharing! This must have been some system / apt-get related package that was missing, it’s not a direct dependency for setting up avrdude, so for now I will not integrate it into install.sh.
I am new to pisound - I got my beta last week. Do I have to update the firmware of the beta card also?
How can I see which firmware is installed?
Is it enough to say on the raspi “rpi-update” for installing the new drivers?
Hi - finally got around to trying this. I can get avrdude running ok, and clone the repo. But after flashing I get this:
pi@raspberrypi:~/pisound-firmware/pisound-firmware $ The kernel module version (0200) and pisound-btn version (0100) are incompatible! Please check for updates at http://blokas.io/pisound
Not sure how to get around this! Any help gratefully received

pi@raspberrypi:~/pisound-firmware/pisound-firmware $
But the button isn’t working: 1, 2, 3 clicks don’t load main, unmount the drive, or set up a wifi hotspot. Long press does shut the system down so at least I know the button is working!
Looks like the install was fine and it is seeing the usb drive when I plug it in.
Thanks - when I try the git pull, or re-run install-pisound.sh I get this:
pi@raspberrypi:~ $ ./install-pisound.sh

I’m not up with GH enough to know what to do, I don’t want to commit changes from here as that would change your updates (?!)
