NAME
Device::BCM2835::Timer - Access to Raspberry Pi's timer
VERSION
Version 1.01
SYNOPSIS
This module's timer() method returns the current value of the Raspberry Pi's internal timer.
use Device::BCM2835::Timer;
say Device::BCM2835::Timer::timer();FUNCTIONS
timer()
This function returns the number of microseconds elapsed since the Raspberry Pi in hand was turned on.
The function gives the value of the 64 bit timer counter installed on the BCM2835 chip. It ossillates at 1 MHz, thus every tick corresponds to 1 microsecond. Internally, it is a pair of two 32 bit registers, which are read and added up correspondently in pure Perl.
