Zvishandiso zve7-segment displays

Chii chinonzi 7-Segment Display?

Chiratidziro chine 7-segment mudziyo wemagetsi unoshandiswa kuratidza nhamba dzedesimali uye mamwe alphabets. Iyo ine zvikamu zvinomwe zvega zvakarongwa mune rectangular fashoni, imwe neimwe inogona kuvhenekerwa yakazvimirira kuita manhamba uye mamwe mavara. Zvikamu izvi zvinowanzonyorwa kuti 'a' kusvika 'g', ine doti rekusarudza (dp) remapoinzi egumi.

Chimiro che7-Segment Display

Iyo yakajairwa 7-chikamu chiratidziro chinosanganisira manomwe e LED zvikamu uye sarudzo yechisere chikamu cheiyo decimal point. Chikamu chega chega chinodzorwa chakasiyana, chichibvumira kumiririrwa kwenhamba kubva pa0 kusvika ku9 uye mamwe mavara ealfabheti.

Mhando dze7-Segment Displays

1. Common Anode (CA): Muchiratidziro cheanode, ose anode (positive terminals) ezvikamu zve LED akabatanidzwa pamwe chete, uye ma cathodes ega (negative terminals) akabatanidzwa kune control circuit.
2. Common Cathode (CC): Muchiratidziro chakafanana checathode, zvose cathodes (negative terminals) yezvikamu zve LED zvakabatanidzwa pamwe chete, uye anode yega yega (positive terminals) yakabatanidzwa kune dunhu rekutonga.

Kusarudza pakati peCommon Anode uye Common Cathode

Kusarudza mhando yakakodzera ye7-segment display-common anode (CA) kana common cathode (CC)-inoenderana zvikuru nedhizaini yako yekugadzira uye nzira yekutyaira. Nepo vese vari vaviri vachiita basa rakafanana, wiring logic yavo uye kuenderana nemaseketi ekudzora anosiyana:

• Common Anode (CA):
  Yese anode yakasungirirwa kune yakanaka voltage, uye chikamu chimwe nechimwe chinoitwa nekukwevera cathode yayo yakaderera (pasi). Iyi gadziriso inowanzofarirwa kana uchishandisa yakaderera-side switching madhiraivha senge transistors kana yakavhurika-muunganidzi zvinobuda.
• Common Cathode (CC):
  Macathodes ese akasungirirwa pasi, uye zvikamu zvinobatidzwa nekushandisa yakanaka voltage kune anode dzavo. Izvi zvinoita kuti zvive nyore kutarisana nemamicrocontrollers kana mutyairi ICs anowanikwa ikozvino pamapini avo ekubuda.

Zvinonyanya Kufungwa Pakusarudza:

1. Kutyaira Circuit Kuenderana - Kana dhizaini yako ichishandisa yakaderera-padivi madhiraivha, CA inowanzova nyore; kune vatyairi vepamusoro-soro kana yakananga MCU zvinobuda, CC inogona kunge iri nyore.
2. Simba Rinobudirira - Mhando mbiri idzi dzinoshandisa simba rakafanana, asi CC dzimwe nguva inogona kuderedza chikamu chechikamu mumaseketi akareruka.
3. Chikamu Kuwanikwa -Mamwe mamodule ekuratidzira kana mutyairi IC akagadziridzwa kune imwe mhando, saka kuwanikwa mune yako cheni yekugovera kunogona kukanganisa sarudzo yako.
4. Chinyorwa Chekushandisa - Kune akawanda maratidziro kana epamusoro-manhamba kuverenga, CA inowanzosarudzwa nekuda kwekuenderana kwayo neanoshanda mutyairi ICs.

Nekunzwisisa misiyano iyi, vagadziri vanogona kuita sarudzo ine ruzivo inova nechokwadi chekubatana pamwe nePCB yavo dhizaini, dhizaini yemagetsi, uye kutonga pfungwa. Iyi sarudzo inoumba hwaro hwenzira dzekutyaira, maseketi ekudzivirira, uye matekiniki epamusoro akaongororwa muzvikamu zvinotevera.

Maonero e7-Segment Anoshanda sei

Kushanda kwechiratidziro che7-segment kunobva pakuvhenekera kwezvikamu zvega. Chikamu chega chega i LED, uye nekusarudza kuvhenekera zvikamu izvi, nhamba dzakasiyana uye mavara anogona kuratidzwa.
