PIC 12F629 - DS1820 - NOKIA LCD

Post by flash005 »

Pozdrav svima,
Napravio sam pločicu za Nokia LCD Termometar od Ivana Novakovića, Sve radi perfektno osim jedne male sitnice koja je meni početniku veliki problem :D.
Ovaj program je koliko sam ja skonto pisan za temperaturni senzor DS18B20 koji koristi 12 bita za očitavanje temperatute, a ja imam DS1820 koji radi sa 9 bita. Sad bi trebao prepraviti program da koristi 9 bita za očitavanje temperature. Da ne ispadne da se nimalo nisam potrudio, napisao sam u mikroC-u program koji radi bez problema ali je prevelik za ovaj pic zato sam odlučio iskorisitti kod od novkivića ali ne razumim baš picBasic pa ako netko može da mi objasni kako da mi ovo proradi.

Code: Select all

http://webspace.webring.com/people/fd/d ... 0schem.JPG" onclick="window.open(this.href);return false; evo shemu koju koristim, znači ovdje su umjesto 4.7 uF stavljeni kondenzatori od 10uF tako je i u mene, i radi mi sve normalno kada koristim pic 16f877A i čak sa pic 12f84, al nikako da proradi na 12f629, za ove piceve imam kod u mikro c-u koji mi radi bez problema al je problem kad ga kompajliram za pic 12f629 prevelik je a neznam ga smanjit :D.

Premalo informacija da bi ti bilo ko dao konkretan odgovor, osim ili nesto nisi spojio kako treba ili nisi podesio jumpere i prekidace na ploci, ili softverska greska, ili ko zna sta...

Gore sam sve naveo, naime testiro sam temperaturni senzor na easy pic 4:
1. spoijo sam prema shemi koju sam gore posao, lcd od nokie 3310 na easy pic 4, isprogramiro pic 12f629, temperaturni senzor se već nalazi na ploči, ali je spojen na pinove ra5 ili re2 pa sam ga samo presvičo kablićem na pin koji meni treba (prema kifinoj shemi tj gp2), NEZNAM GDJE SAM POGRIJEŠIO. LCD JE RADIO BEZ PROBLEMA TJ PRIKAŽE MI SAMO SLIKU, A ZA TEMPERATURU POKAZUJE 0.05 STUPNJEVA ČINI MI SE
2. al kad sam testiro na uređaju radi bez problema. :S

Moguce da na tim linijama postoji jos kojesta zakaceno, pa pull up ne moze da izgura dovoljno visok napon...
Opet ko nema easypic4 tesko da ti sta moze reci. Uzmi instrument u ruke pa to premeri sve kako valja i spada, pa ces onda znati...

Koliko znam taj 12 bitni može učitavati i samo 9 bita, tj podešavaš rezoluciju softwareom. Moj ti je savijet da uzmeš dokumentaciju z taj IC, tmp. sensor, tamo ti je sve pojašnjeno i na osnovu toga napišeš driver za rezoluciju kaj ti treba i uživaš u svom termometru.
Obično demo programi ne sadržavaju kompletne mogućnosti sklopa već počesto samo jednu do dvije opcije.

Ja sam si napravio sličan uređaj, nokia LCD (3310), DS1820 (12 bitni) ali za ATm8. Trebao mi je za upravljanje s termo peći, s podesivom rezolucojom i kompletnom obradom znakova kao i posebno dizajniranih znakova i još nekih grafičkih dodataka.
Uzmeš nolikin Logo manager, napraviš sliku i transate-aš dobiveni kod na prihvatljiv 8 bitnom microračunalu pa dobiješ grafiku kakvu poželiš. Postaviš timere, više njih, razne upravljače funkcije da uređaj dobije neki smisao, upotrebljivost.
Pozdrav
