Raspberry Pi 5, while testing PiSound, I can’t use button.
Built pisound-btn from git clone, /usr/local/bin/pisound-btn can’t write to /sys/class/gpio/export
Does anyone get the button to work?
What is the output of:
ls -la /sys/class/gpio/

Are you trying to run pisound-btn as the regular user? Is it member of the group gpio?
What is the output of groups and whoami?
As the regular user ,
/usr/local/bin/pisound-btn
Failed writing to /sys/class/gpio/export! Error 22.
I’m a member of the gpio, and
cat /etc/group
gpio:x:993:ME
systemctl status

Looks like the pin numbering got changed on Raspberry Pi 5:

Try changing these original lines in pisound-btn.c:
static int gpio_is_pin_valid(int pin)
{
return pin >= 0 && pin < 100;
}
to:
static int gpio_is_pin_valid(int pin)
{
return pin >= 0 && pin < 1000;
}
And:
static int g_button_pin = 17;
To:
static int g_button_pin = 416;
Then run make && sudo make install again.
