Displej na bicykl

1. června 2007 v 16:48 | hawelson |  SVĚTLO
Popis funkce:
Displej na bicykl je přístroj, který umí vykreslovat na kole bicyklu nápis nebo jednoduché obrázky.Jeho princip je v postupném vykreslování po jednotlivých sloupích. Oko ozářené zábleskem LED diody ještě na chvíli zachovává tento záblesk na sítnici. Pro oko to vypadá jako by LED ještě chvílí svítila. Níže popsaný displej tohoto jevu využívá a díky němu stačí pouze 8 kusů LED k zobrazení velice dlouhého nápisu. Podobný princip se využívá i v CRT obrazovkách kde stálé svítí pouze jeden bod (u barevné obrazovky 3 body) a ten se pohybuje po celé obrazovce, čímž vnímáme, jako by byl obraz celý a díky vysoké rychlosti i plynulý.U tohoto displeje taky záleží hodně na rychlosti otáčení kola. Čím se kolo otáčí rychleji, tím je nápis více plynulý a lépe čitelný.
Technické údaje:
Napájení: 3,7V DC
Odběr standby: <0,1mA
Odběr při vykreslování: 2-100mA (podle počtu aktivních bodů)
Výstup: 8LED (libovolná barva nebo kombinace barev)
Synchronizace otáček: jazýčkové relé a magnet.
Popis zapojení:
Schéma zapojení:
Srdcem celého obvodu je PIC 16F84, do kterého je třeba naprogramovat nápis, který se bude následovně bude vykreslovat. Rychlost vykreslování záleží na rychlosti provádění pracovních cyklů mikrokontroléru PIC 16F84, čili taktu. Rychlost taktu, tím i rychlost vykreslování, nastavujeme trimrem TR, který je zapojen s C2 a oscilátor pro generování taktovacího kmitočtu pro PIC. Čím bude odpor TR větší, tím bude taktovací frekvence nižší a nápis bude delší (využití při nižších otáčkách). R spolu s jazýčkovým relátkem JR slouží k synchronizaci začátku nápisu, aby se nápis nepohyboval volně po kružnici při změně otáček. Jazýčkové relé použijeme nejlépe s tachometru, kde slouží také pro snímaní otáček. Magnet pak umístíme na statickou část bicyklu. Keramický kondenzátor C1 slouží pouze pro vyfiltrovaní rušení. LED1-8 slouží k vykreslování znaků. Celé toto zapojení můžete napájet buď třemi NIMH akumulátory zapojenými do série, které budou mít 3,6V a nebo lepší je použít Li-ion akumulátor (3,7V). LED diody nepotřebují do série rezistory, protože PIC má při spínání kladného napětí vnitřní odpor asi 85Ohm. Je dobré ještě mezi akumulátor a tento obvod zapojit vypínač, protože při delším nepoužívaní by se akumulátor zbytečně vybíjel.
DPS:
Strana spojů (DPS je určena k vytisknutí v rozlišení 300DPI):
Strana součástek - osazení:
Při osazování DPS nesmíme zapomenout na drátovou propojku pod IO. Celou DPS upevníme na paprsky kola pomocí vnitřků z elektrických čokolád, který nasadíme na dva protější paprsky. Na vnitřky paprsků napájíme, kolem jejich obvodu, hrubý nejlépe měděný drát a necháme jeden jeho konec přečnívat pár centimetrů. Tento konec drátu je pak třeba připájet k měděným plochám na DPS určeným pro uchycení celé DPS. Akumulátor je třeba uchytit buď podobně, a nebo zvolit jiný způsob. Jazýčkové relé upevníme podobně jako se upevňuje na tachometru, rozdíl bude v tom, že jazýčkové relé bude na rotační části a magnet na pevné konstrukci bicyklu. Vypínač odpojující obvod je nejlépe připevnit k akumulátoru.
Seznam součástek:
R = 47K
TR = trimr 22K RM 5mm
C1 = 100nF
C2 = 22pF
D1-D8 = LED diody dle volby
JR = malé jazýčkové relé + permanentní magnet
IO = PIC16F84
Patice na IO 18 pin
Akumulátor 3,7V
Vypínač
Programování mikrokontroléru:
Praktické programování mikrokontroléru je popsáno v článku točící se hodiny. HEX program pro nápis "HAWELSON.blog.cz" je dole na této stránce. Pokud si chcete vytvořit vlastní nápis, stačí pouze přepsat program, který naleznete ZDE. Pak stačí najít program pro překládání assembleru do HEX (např. MPASM) a svůj přeložený program nahrát do mikrokontroléru. Program neupravuje délku nápisu podle otáček, tedy čím bude mít kolo větší otáčky, tím se bude nápis více natahovat. Proto si nastavte na trimru TR ideální délku.
Na stránkách http://svetelektro.com/ vzniklo fórum k tvorbě vlastního nápisu na tento displej viz odkaz ZDE, kde je popsáno a vysvětleno vše dopodrobna o programování tohoto displeje.
Obrázky funkčního displeje:
DPS na obrázcích nebude odpovídat DPS v návodu, protože jsem ji udělal už před časem a nepoužil jsem výrobu fotocestou.
DPS (není to ta, co je na schématu, ale zapojení je totožné):
Test funkce mávnutím ve vzduchu (text se postupně po jednom sloupci vykresluje):

Displej umístěný na bicyklu:
Čím jsou vyšší otáčky kola, tím se nápis více natáhne. K nastavení požadované délky nápisu slouží trimr který je ve schématu.
Podobný displej, s jednodušším vložením vlastního nápisu, ale složitější na konstrukci najdete na odkazu: http://www.svetelektro.com/clanky/uz-je-to-tu-led-displej-editor-textu-272.html
