This patch adds support for using
beep
on a Raspberry Pi, using an old BIOS speaker or piezo buzzer attached to its GPIO PWM pin.When not running as root, ugly
system()
calls are used to call thegpio
binary included withwiringPi
. Note that this is significantly slower, as the binary needs to be called 5 times for each tone! You might be better off runningbeep
assuid
.The original Makefile has been replaced with a Makefile.in to accommodate the conditional compilation with
wiringPi
support.Build with
./configure && make
.
