*
* This program is an example of a "free-standing" C application. If you
* modify this example and try to call C library functions such as printf, they
* will NOT work unless you explicitly initialize the system, such as in the
* hello_alt_main software template. Please see below for details.
*
* Description
* *************
* A very minimal program that simply shifts an LED back and forth.
*
* Requirements
* **************
* According to the ANSI C standard, freestanding programs "own" the hardware,
* and cannot rely on system-services or device-drivers being initialized prior
* to program-start. A freestanding program is responsible for initializing all
* hardware devices, device-drivers, and system-services. Many embedded
* programs are, by nature, freestanding. The author relinquishes any illusion
* of running their program on a workstation.
*
* This example is a freestanding program because it's entry point is the
* function:
*
* void alt_main (void)
*
* As opposed to "main()" as a "hosted" application would (see the
* "hello_world" example).
*
* Upon entry to alt_main():
* - The CPU's caches (if any) have been initialized.
* - The stack-pointer has been set.
* - That's all. The rest is up to you.
*
* If you modify this example and try to call C library functions such as
* printf, they will NOT work unless you explicitly initialize the system.
* If you wish to use C library calls, it is strongly suggested you start
* with the hosted hello_world template which uses main() as it's entry
* point.
*
* On the other hand, if you want to write a program that gets-in even
* earlier, you will need to provide your own assembly-language machine-setup
* code by defining the symbol "_start". Any definition of _start in your
* directory will override the library definition. You can find source code
* for the Nios II library _start here:
*
* <NiosII-Kit-Install-Dir>/components/altera_nios2/HAL/src/crt0.S
*
* This software example requires a system with a PIO peripheral named
* "led_pio". The software example will run on the following hardware
* examples:
*
* Nios Development Board, Stratix II Edition:
* - Standard
* - Small
* - Full Featured
*
* DSP Development Board, Stratix II Edition:
* - Standard
* - Small
* - Full Featured
*
* Nios Development Board, Stratix Edition:
* - Standard
* - Small
* - Full Featured
*
* Nios Development Board, Stratix Professional Edition:
* - Standard
* - Small
* - Full Featured
*
* Nios Development Board, Cyclone Edition:
* - Standard
* - Small
* - Low Cost
* - Full Featured
*
* Peripherals Exercised by SW
* *****************************
* The hello_led.c program simply shifts an 8-bit variable back and forth,
* writing the variable's value to the system's LED PIO peripheral on every
* iteration.
*
* Software Files
* ****************
* hello_led.c - Main C file that contains the simple led manipulation routine.
