hello to everybody  i would like to use timestamp to monitoring my application time. In sopc builder i set timer 1 msec . I follow documents and then i include the header file such as the documents told me. but when i compile to download exe file (.elf ) occur a console warning that  tell me is notpossible to find header file . Very strange . Somebody already use this function? thanks for helps  ciao  walter

Could you post the warning message you are seeing?

Have you defined the timestamp timer in the IDE (checkbox on the System Library properties page)? The timestamp functions do not make use of the system clock timer.

[Altera_Forum]

could you be clearer? 

Please explain to me exactly informations about your question slacker thanks http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/wink.gif  walter

[Altera_Forum]

Do you have a "Timestamp timer" defined on the System Library properties page? If you do not, or don&#39;t know what I&#39;m referring to, please go look at this page (in the IDE).  

 The timestamp functions will not be compiled into your System Library unless you have one selected/defined.

[Altera_Forum]

these are the declarations related to the timer.  

In sopc builder I have setted as from manual, but here in the file  result me "none".You can see at the end of file  # define SYSTEM_TIMER_NAME "/dev/system_timer"# define SYSTEM_TIMER_TYPE "altera_avalon_timer"# define SYSTEM_TIMER_BASE 0x00900800# define SYSTEM_TIMER_IRQ 1# define SYSTEM_TIMER_ALWAYS_RUN 0# define SYSTEM_TIMER_FIXED_PERIOD 1# define SYSTEM_TIMER_SNAPSHOT 1# define SYSTEM_TIMER_PERIOD 1# define SYSTEM_TIMER_PERIOD_UNITS "ms"# define SYSTEM_TIMER_RESET_OUTPUT 0# define SYSTEM_TIMER_TIMEOUT_PULSE_OUTPUT 0# define SYSTEM_TIMER_MULT 0.001# define SYSTEM_TIMER_FREQ 50000000 # define ALT_SYS_CLK SYSTEM_TIMER# define ALT_TIMESTAMP_CLK none# define ALT_MAX_FD 32  I follow instruction from manual . It&#39;s possible make some change in this file , without regenerate in sopc  and compile in quartus II ? If not , how i have to set flags in sopc builder ? thanks for the answers  ciao  walter

Walter, 

 I&#39;d advocate having two timers in your SOPC Builder system, one for the system clock timer and one timestamp timer.  The reason your design is failing is  #define ALT_TIMESTAMP_CLK none  Unless your SOPC Builder system has two timers, already, you&#39;ll have to add another one and re-generate/re-compile. You could also use the "system_timer" timer as your timestamp clock, but then you wouldn&#39;t have a system clock timer, and I don&#39;t advocate that!  Both the full_featured and standard "examples" have timestamp timers as well as system clock timers. You should change your SOPC Builder design so that it does too.  The key part, that you missed, is that you&#39;ve got to make sure your System Library properties are properly configured, prior to compiling your application. A quick browse through the Nios II IDE online help yields  Timestamp timer - Associates the timestamp driver to a timer device in the SOPC Builder system. The Timestamp timer and the Periodic system timer cannot specify the same physical device.  Unless you have a gigantic system, adding an additional timer to it shouldn&#39;t add more than a few seconds of generation/compilation time.  Best of luck,  - slacker

yesterday i also add a new timer  

Generate system and ricompile in quartus II but in the system.h file i only read a new timer added , while the last lines at the end of file was the same  "none2 .  http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/sad.gif  p.s. if i set "Writebke period " flag i loose full featured option I have to not set this flag from the manual if i want to use  timestamp It&#39;s very uncredible , every little thing became big in this system  To use timestamp is very easy from the manual , but what a have to do  is not possible to know   http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/dry.gif

Yes... the default for Timestamp timer, in the System Library Properties page, is none. The build process, used by the IDE, will not (cannot, could not) automagically detect your new timer, you have to tell it to include the timestamp timer, by setting on the System Library properties page. 

 The timestamp timer does, by the way, work. You just have to understand how important the System Library properties page is to the build process.  Cheers,  - slacker

yes i know  

when i build a system in NIOS II IDE , the compiler take the system  .ptf , after quartus II compile , and after sopv builder generate. So during building , IDE produce system. h , usiing address base specified in sopc  builder , and map all register of all component used . Anyway , i posted the system.h above , and then i added a new timer  in cops builder , generate , update in quartus II and "start compilation " again . After that in NIOS II IDE i build or rebuild all . In the system.h file appear a new timer , but the last three lines about  timestamp remains the same . At the end i cannot understand what to do , really ......  http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/sad.gif http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/sad.gif http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/sad.gif  I saw all documentation files , but they only explain how to use timestamp  with some sample codes . they explain that it&#39;s possible to use timer driver in two ways , like timestamp or system timer and how to set the flags property page in sopc builder ... ...nothing else  Tomorrow i try to use my oscilloscope connected to the pc and set one output  port bit in the beginner and reset at the end of my program  And after try to understand the cycle time .  http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/blink.gif

Ok... here&#39;s the step-by-step for changing your syslib properties: 

 1. Right-click on your project, in the IDE, and select "System Library Properties"  or right-click on your System Library project and select "Properties". 2. Change "Timestamp timer:" from "None" to whatever your new timer&#39;s name.  - Take a look at any full_featured design&#39;s "high_res_timer" to see how to properly configure an interval timer in SOPC Builder. 3. Click OK to apply the changes. 4. Rebuild your project, and you should see the correct timestamp# def&#39;s. in your system.h file.  Hopefully, that will get you where you want to go.  BTW, both the Dhrystone software example and the software for the custom instruction tutorial make use of timestamp timers. Perhaps, you could refer to these example, in their entirety, prior to moving forward with your development?  Cheers,  - slacker

CORRECT !!! http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/smile.gif  

I try to write TIMER_0 (my second timer in system) direct in the file  instead "none" , but after generation IDE overwrite with "none" again. So i try as you suggest , because i saw the post later , and IDE compile correct . After that my code was compiled successfully. I change period from ms to us but the result is 0 (us) NIOS II is the faster system that i never see .  http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/biggrin.gif  Maybe there is other little problem because alt_timestamp return  alwais 0 . ...mmmmmmmmmmmmmm http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/dry.gif  Otherwise , Slacker , thank you for your interest  you are very nice   http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/wink.gif  Now i want to check why doesn&#39;t work properly  have a good night (for me &#39;cause in italy now it&#39;s 1.30 ) ciao  walter

nothing ..... 

the function alt_timestamp() returns always 0  http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/sad.gif  ciao  walter
