A few months ago i connected a pc to pic using 2 com port. One for debug, other one for commands and data.
First of all you will need a pc with 2 com ports or usb to serial convertors.
I wrote a visual basic program for this. (Real program in delphi but it is only for...

pic16f84 clock 32768
hi,
look at
hxxp://users.skynet.be/bk317494/
you will find DS1307 real time clock project...
if you want to use single pic like pic16f84 and interrupts, most probably you want 1 interrupt per second. if then, look at
hxxp://www.picant.com/c2c/c.html
you find...
also you may try
void DoEvents(void)
{
MSG msg;
while(PeekMessage(&msg,NULL,0,0,PM_REMOVE))
{
TranslateMessage(&msg);
DispatchMessage(&msg);
}
}
it is working but application doesn't gracefully terminated...
you must exit from this loop.
while...
try this one. no another thread.
void DoEvents()
{
MSG dispatch;
while (::PeekMessage( &dispatch, NULL, 0, 0, PM_NOREMOVE))
{
if (!AfxGetThread()->PumpMessage());
}
}
in your loop call call DoEvents();
while (...........)
{

Re: Thread Programming
Note:
TLS : Thread Local Storage
VB5, VB6 uses TLS to store ERR object, APP objects etc.
this means accessing them from another threats may not good for your program.
sure that best way is using dlls.
Re: Thread Programming
if you ask for standart exe files, of course its possible.
in vb6 you can create and control threads via apis. but it can be difficult.
no native support for threads in std exes.
there are still main problem if you choose api way...
vb5, vb6 uses tls for main objects...
basically they are totaly different.
in dotnet everything is an object based.
main feature = .net framework.
.net framework starts new concept for programmers.
.net doesn't compile program into exe files like java. .net programs requires .net framework to run. it is possible but not now...
vb 6.0 delay without timer
TRUNGDPHAN asked: Do you have any ways to delay that doesn't depend on the system?
the result of QueryPerformanceCounter/QueryPerformanceFrequency is system INDEPENDED. look attachment.
vb 6.0 , put timer delay
sorry, i'm away.
Please read papyaki's post . Performance Counter is comes from hardware and can change from system to system.
(seconds) = QueryPerformanceCounter / QueryPerformanceFrequency
if you read two value you can get difference...
delay function in vb 6.0
TRUNGDPHAN,
you can't use VB's timer component to wait/pause 10ms.
also timer function is useless for 10ms.
check your system. Timer Component and timer function's resulation depends on computer you are using.
min resulation is from 16.25ms to 55ms in most...
