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.

|
|
This example uses the free running ARM timer, not the 64 bit system
|
|
timer as in blinker02 but the so called ARM timer.
|
|
|
|
The system clock appears to come up at 250MHz as documented. Divide that
|
|
by 250 to get 1Mhz on this free running ARM timer. Then count to four
|
|
million ticks between led state changes and the led will change state
|
|
every four seconds.
