See the top level README for information on where to find the
|
|
schematic and programmers reference manual for the ARM processor
|
|
on the raspberry pi. Also find information on how to load and run
|
|
these programs.

There is a free-running 64 bit timer, super easy to use, just read it.
|
|
|
|
Based on a couple of experiments, without messing with anything else it
|
|
appears that the timer is runing at about a megahertz, 1 million ticks
|
|
per second.

Hmm, there are comments in the manual about the system clock coming up
|
|
at 250MHz. I wonder if this system timer is 250MHz/256 = 0.976MHz.

This directory contains an example for the ARM11 raspberry pi, for the
|
|
ARM11 based A+ and B+ see the plus directory and for the Cortex A7 based
|
|
raspberry pi 2 see the pi2 directory.
