µTasker general / tasking

« on: April 12, 2011, 11:56:13 AM »

Hi I want my task not to run whenever a message comes but only at periodic intervals. I mean it should handle the message only at next round. Can one of those do this job?

{ "X-turnstile-application",       fnTurnstileApplication,  LARGE_QUE,  (DELAY_LIMIT)(2 * SEC),(DELAY_LIMIT)(3 * SEC), UTASKER_GO} or
{ "X-turnstile-application",       fnTurnstileApplication,  LARGE_QUE,  (DELAY_LIMIT)(2 * SEC),(DELAY_LIMIT)(3 * SEC), UTASKER_STOP}

BTW what is the exact difference between those? I have already read the uTasker operating system basics. But it is unclear...
Thx...

µTasker general / WatchDog

« on: April 09, 2011, 02:40:40 PM »

Hi all,
I am having trouble with my app. It simply has 2 tasks one for  general application and the other for receiving/sending rs485 commands from  uart2. Here is a gist of  : my task table

{ "Wdog",      fnTaskWatchdog, NO_QUE,   0, (DELAY_LIMIT)( 0.3 * SEC ),  UTASKER_GO},
  { "app",       fnApplication,  MEDIUM_QUE,  (DELAY_LIMIT)((0.10 * SEC) + (PHY_POWERUP_DELAY)), 0, UTASKER_STOP}, // Application - start after Ethernet to be sure we have Ethernet handle
  { "X-turnstile-application",       fnTurnstileApplication,  LARGE_QUE,  (DELAY_LIMIT)(2 * SEC),(DELAY_LIMIT)(0.1 * SEC),  UTASKER_STOP},  // main application
  { "x-PP_Receive", fnTaskPPReceive, LARGE_QUE,   (DELAY_LIMIT)(NO_DELAY_RESERVE_MONO), 0,  UTASKER_STOP}, // uart receiving task

Here is an debug output from uart0

APP is working
Turnstile app is working
pp receive started to work
App is working

I assume that while PP is working device restarts maybe because of watchdog. So in gist, how can i kick the watchdog to prevent it from resetting?
