<p><b>AVR-Specific Issues</b>.
|
||||
The basic AVR port is solid and biggest issue for using AVR is its tiny SRAM memory and its Harvard architecture.
|
||||
Because of the Harvard architecture, constant data that resides to flash is inaccessible using "normal" memory reads and writes (only SRAM data can be accessed "normally").
|
||||
Special AVR instructions are available for accessing data in FLASH, but these have not been integrated into the normal, general purpose OS.
|
||||
</p>
|
||||
<p>
|
||||
Most NuttX test applications are console-oriented with lots of strings used for printf and debug output.
|
||||
These strings are all stored in SRAM now due to these data accessing issues and even the smallest console-oriented applications can quickly fill a 4-8Kb memory.
|
||||
So, in order for the AVR port to be useful, one of two things would need to be done:
|
||||
</p>
|
||||
<ol>
|
||||
<li>
|
||||
Don't use console applications that required lots of strings.
|
||||
The basic AVR port is solid and your typical deeply embedded application should work fine.
|
||||
Or,
|
||||
</li>
|
||||
<li>
|
||||
Create a special version of printf that knows how to access strings that reside in FLASH (or EEPROM).
|
||||
</li>
|
||||
</ol>

* \brief Events
|
||||
*
|
||||
* Event moudle offer real-time signaling and handling of real-time
|
||||
* events at precision of system resolution clock_t.
|
||||
*
|
||||
* Events are based on periodic timers, where each started event starts
|
||||
* counting at its relative time = 0, and overflows at given period.
|
||||
* Overflow is signalized by posted event that is handled by the
|
||||
* event_eventhandler() called by each thread or task working with
|
||||
* Events.
|
||||
*
|
||||
* Events may be used inside one thread or task only or between tasks
|
||||
* and threads. An event can also be bind to another event i.e.:
|
||||
* - System Clock may issue a notification about Power Failure
|
||||
* - Other threads may connect to this event and when handled, they may
|
||||
* inquiry for pricise time when this event has happend, using the
|
||||
* event_gettime()
|
||||
*
|
||||
* Or system is about to control a process, and instead of looping and
|
||||
* inquiring for time, system timers offer simple and effective
|
||||
* mechanism to control timed actions:
|
||||
* - First event is about to wait 5 seconds, then it must assert some
|
||||
* switch, triggering another event after 2 seconds, to check the
|
||||
* state of the system.
|
||||
* - After 2 seconds new event is triggerred, if it is time criticial
|
||||
* it may check for the overrun time and handle further actions,
|
||||
* - ...
|
||||
*
|
||||
* Each event is denoted by a callback function event_callback_t, and
|
||||
* an argument. Posted event with the same callback but different
|
||||
* argument is treated as different event, while the same callback with
|
||||
* the same argument replaces previously started event.
