PowerOnDelay na OverKill!!! [Zilog]

[marcelino]

Totoo OVER KILL talga to...
At mas mahal ha!!! heheh

Most part of the code is based on sir paranz tutorial.

Code:

/*
   Power On Delay For Air Condition with Override Switch Using Z8F0823  

* Timer0 -  For Direct LED drive display during waiting time
* Timer1 -  CountDown tick for the given TurnOnTime (in seconds)

Processor : Z8F0823
Oscillator: Internal Oscillator : 5.53 MHz (to be exact = 5.52960MHz)
 

*Based on the tutorials of Sir Paranz of Elab

Some Pics of the Prototype:
Nakakatawa yang transformer.... may brand palang "tamagawa". di ba may brand na YOKOGAWA??!


the beneath, showing the procie and the voltage regulator and the not good soldering. Yang maraming LEAD, in preparation sa heavy load ng Aircon.


Bukas, nasa kahon na yan... hehehe


Sana kayanin ng RELAY ang AirCon!


Once again, nothing special! but just to inspire...

Salamat sir Paranz. datasheet at compiled tutorial mo lang ang references ko! heheh

[tiktak]

overkill nga sister nice one

[marcelino]

^
hehehe....

ipinapakita din dito ang fast prototyping kapag MCU ang gagamitin!

[rdpzycho]

sis marce pwede ka pang magdagdag ng features like for an hour 20 minutes lang nakasindi 'yung aircon then next hour na ulit. alam ko nagkaroon ng ganitong project sa electronic enthusiast. distributed kasi 'yung on time nung aircon rather than ilang oras tapos puro fan na lang. same concept nung sa REF na pinapatay sindi for minutes sa gabi. huwag lang masyadong magkakalapit ang intervals dahil sira naman ang compressor.

[marcelino]

sis marce pwede ka pang magdagdag ng features like for an hour 20 minutes lang nakasindi 'yung aircon then next hour na ulit. alam ko nagkaroon ng ganitong project sa electronic enthusiast. distributed kasi 'yung on time nung aircon rather than ilang oras tapos puro fan na lang. same concept nung sa REF na pinapatay sindi for minutes sa gabi. huwag lang masyadong magkakalapit ang intervals dahil sira naman ang compressor.

heheheh....

medyo naisip ko yan nung habang nageetch na ako!

to make it simplier, I was thinking of putting some DIP switches. each switch stands for a solution. parang set na.... para ba mas madali! makokomplicate kasi kung may interface pa. whereas, di naman laging gagalawin yan.

pwede naman siguro, sa version 2. may mangilan-ngilan pa naman akong processors dito! hehehe

medyo urgent lang kasi to. panay kasi ang brownout ngayon dito at bumabalik kaagad! one month palang yung aircon namin baka masira kaagad. though under warranty, mainit naman matulog pag-gabi!

[insomartin]

ngayon ko lang nakita... it's not overkill  OVER-ENGINEERED!
i think the next best thing is to add a safety feature...

i did this using 555 timer kapag christmas (lights)... it simply means kung 50% duty cycle it means that 50% din yung consumption. but since may thermostat yung air con that randomly on's and off.. (ALMOST RANDOM) i got a feeling na hindi economical na mag on off... i can't explain it clearly but... wait i'll try to draw it..

hahaha... over engineered nga ang tamang term!

perhaps, yan kasi ang available saakin. kasi naman... mga napulot ko yan eh... pati nga yun enclosure!


safety feature hmmm... can't think of one for such gadget.

yup. kaya ang pinaka-economical ta-timing-an talaga 'yung compressor. hehehe. inorasan ko na 'yung sa kwarto, 12 minutes (after mag-on ng compressor), nearly constant kapag ganitong panahon (mga 25 minutes patay 'yung compressor, pero kapag pinatay ko na, aabot naman ng more than 40 minutes 'yung acceptable na lamig). lalamig na 'yung kwarto, pwedeng fan na lang muna. either i-detect kung kailan mag-on 'yung compressor o chambahan lang sa oras.

kakailanganin palang magsampling. magkakaiba pala ang requirement ng rooms. ganitong nasa bahay lang... shared pa sa kabilang kwarto using exhaust fan.

di ba part pa to ng mga HVAC studies and researches?

[rdpzycho]

medyo ganun na nga sis. dahil nga sa thermostat nung aircon. hehehe.

[marcelino]

medyo ganun na nga sis. dahil nga sa thermostat nung aircon. hehehe.

ang thesis ko nga sana ay HVAC application... kaso wala akong building na pwedeng malagyan ng testing. hehehe
ang objective sana ay parang maanticipate na ng system ang lamig naigegenerate sa particular na oras ng araw. AI application na din...

[insomartin]

and... from HVAC naman magiging Climate Control... ayannnnn naah!

@marce

 wala bang timer0/timer1 for CCS

@marce

 wala bang timer0/timer1 for CCS

meron...

[RaffT]

oops what I meant was wala ba katapat ang code na yan for CCS? hehe

[paranz]

nice project sis marce..

some of my students, ganito din project nila with included timer IC pero PIC ang gamit

[marcelino]

oops what I meant was wala ba katapat ang code na yan for CCS? hehe

hehehe... tinawag kasi ako ni misis!
ayan, gumawa ako ng simple counter using timer0 and timer1 sa CCS.

di ko lang gusto kasi gumamit pa ako ng interrupt.

Code:

#include <16F877A.h>

#FUSES NOWDT,HS,NOPUT,NOPROTECT, NODEBUG, NOBROWNOUT, NOLVP, NOCPD, NOWRT

#use delay(clock=4000000)


int   TIMER0_overflow_flag;
int   TIMER1_overflow_flag;

#int_RTCC
void  RTCC_isr(void)
{
   TIMER0_overflow_flag = TRUE;
}

#int_TIMER1
void  TIMER1_isr(void)
{
   TIMER1_overflow_flag = TRUE;
}



void main()
{
   int16 timer0_count, timer1_count;    //overkill
   char t0,t1;
   setup_timer_0(RTCC_INTERNAL|RTCC_DIV_8);     //overflow every 2ms
   setup_timer_1(T1_INTERNAL|T1_DIV_BY_8);      //524ms
   
   enable_interrupts(INT_RTCC);
   enable_interrupts(INT_TIMER1);
   enable_interrupts(GLOBAL);

   set_tris_b(0x00);
   output_b(0x00);
   
   timer0_count = 0;
   timer1_count = 0;
   
   
   while(true)
   {
      if (TIMER0_overflow_flag)
      {
         TIMER0_overflow_flag = FALSE;
         timer0_count++;
         if (timer0_count == 1000)    //1000*2ms = 2 seconds
         {
            timer0_count = 0;
            output_high(PIN_B0); //OpenHatch();
         }
      }
     
      if (TIMER1_overflow_flag)
      {
         TIMER1_overflow_flag = FALSE;
         timer1_count++;
         if(timer1_count == 10)          // 2*524ms =~ 5sec
         {
            timer1_count = 0;
            output_high(PIN_B1); //LaunchMissile();
         }
      }
   }

}

[marcelino]

nice project sis marce..

yeah... maganda nga itong activity project. una, tangible at di masyado magastos... simple yet, mamamaster na din yun usage ng TIMERs.
