Is it possible to use a TFPTimer in the console of my Raspberry ZERO
with FPC 3.2.2 ? Or is it not supported ?

It does not seem to run and i did see a access violation or two.

Anybody Example code ?

Greets, Wouter

Of course it is working on a form, but now in the console.

Now i am doing this:

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i procedure
TAppProgBench.FTimerTimer(Sender: TObject);begin  //
log('Timer1Exec',yellow);  end; 
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i   //*******
**********************************************************************
*********   FTimer := TFPTimer.Create(nil); FTimer.OnTimer :=
@FTimerTimer; FTimer.Interval := 1000; // in
milliseconds FTimer.Enabled := True;         FTimer.StartTimer;  //***
**********************************************************************
*************

Anybody knows what to change ? Grtz W

Console applications don't have a message loop so TFPTimer won't work.
Just start a worker thread and measure time with GetTickCount64. See
attached project for more details. Let me know if it works on
Raspberry.

Small update for this thread (as it just happened that I stumbled upon
it in search for something else).

GetMem's example works like a charm, however:

TFPTimer does work when you enable UseTimerThread which (pretty much
unsurprisingly) creates a thread for you in the background without the
need to do that manually. Ofc. it does require threads so if your
platform requires it then do not forget to add your platform specific
threads unit as first entry to your uses clause (don't worry though as
the runtime library will explain that to you as well in case you
forgot   ).
