Kako odraditi kod da prilikom reseta ili gasenja i novog paljenja uredjaja u memoriji ostanu zapisana podesavanja?

Code: Select all

TERMO VAR PORTA.0  'Senzor
HTEMP VAR PORTB.0  '+
LTEMP VAR PORTB.1  '-
ENTER VAR PORTB.2  'Potvrda (Enter)
EXIT  VAR PORTB.3  'Izlaz (Reset, Unos, Sve izpocetka)
HEAT  VAR PORTC.0  'Grejac
 
SENZOR  VAR WORD   'Promenljiva za smestanje sa merenja sa senzora
MAXTEMP VAR WORD   'Promenljiva za podesavanje temperature, Tasteri +-
OPSEG   VAR WORD   'Promenljiva za histerezis, Tasteri +-
REF     VAR WORD   'Promenljiva za racunanje
PT      VAR WORD   'Promenljiva za prikaz temperature  
HY      VAR BYTE   'Promenljiva za prikaz histereze  
ZT      VAR BYTE   'Promenljiva za prikaz zadane temperature
I       VAR BYTE   'Promenljiva za for next naredbe

 Primer :
 
 LCDOUT$FE,1,"TEMP JE: ", DEC ZT,178,"C"
 
 LCDOUT$FE,$C0,"Hysteresis  ",DEC HY,178,"C"

Ako PIC ima EEPROM onda ovako

Code: Select all

tmp1 var byte
tmp2 var byte

read 1,tmp1
read 2,tmp2
MAXTEMP.lowbyte =tmp1
MAXTEMP .highbyte=tmp2
.
.
.
.
.
.
.
.
.
.
.
.
Podesavanje
tmp1=MAXTEMP.lowbyte 
tmp2=MAXTEMP.highbyte
write 1,tmp1
write 2,tmp2

Signal kondicioner

Post by electron »

Pokusao sam da odradim kondicioner prema prilozenoj shemi, ali mi je javlja problem, naime tek kad na +Vcc/-Vcc dovedem +5V/GND on nekako proradi, medjutim potenciometi ne reaguju.Prilazem shemu (i u eaglu), pa ako neko nesto vidi...? Dali -Vcc i GND treba da budu spojeni?

Reseno +Vcc=+12V, -Vcc=-12V, GND=0V, zaboravio 0V :idea: Sve radi uredno, kao i podesavanja 0V i +5V
