Ngaahi Fakahinohinó:

<1>: Malohi

ʻOku fekauʻaki ʻa e konga ki mui ʻo e module mo e taulanga GND, pea ʻoku fehokotaki ʻa e 3.7V mo e feituʻu ʻoku kovi mo lelei ʻo e maʻuʻanga ivi malohi (puha ʻuhila) takitaha. ʻOku fokotuʻu atu ʻa e maʻuʻanga ivi ke fakaʻaongaʻi ha puha ʻuhila pe ko ha transformer ʻoku ne puleʻi ʻa e malohi. ʻOua naʻa fakaʻaongaʻi ʻa e switching ngaahi nāunau mālohí taʻe ʻi ai ha meʻasivi (hange ko e telefoni toʻotoʻo fuʻu pupuhaʻia, ngaahi pangike ʻuhila, liliu e nāunau ki he mālohi ʻo e TF-TF), me'a kehe, ʻe uesia ʻe he kaunoa tuʻo lahi ʻoku ʻomi ʻe he konga ʻo e maʻuʻanga ivi ʻa e ngaue angamaheni ʻo e module ko ʻeni. Ko e voltage angamaheni ʻo e module ko ʻeni ko e 3.0-5.0V, pea ʻoku ʻikai totonu ke lahi ange ʻa e maʻuʻanga ivi ʻoku maʻu mei he maʻuʻanga ivi ko ʻení.

<2>: 'Enitena

ʻOku fakaʻaongaʻi ʻa e taulanga LOO ke fakafehokotaki ʻaki ʻa e FM ʻenitena. Ke lava ʻo fakahū lelei ange ʻa e ngaahi fakaʻilonga FM, ʻoku fokotuʻu atu ke fakafehokotaki ha 75cm-loloa ʻenitena, pea ʻoku ʻikai totonu ke ʻi ai ha ngaahi faingataʻa ki he mamaʻo taha ʻe lava ofi ki he ʻenitena.

<3>: Fakatonutonu ʻo e tuʻo lahi hono faí

ʻOku fie maʻu ke fakaʻaongaʻi ʻe he module ko ʻení ha komipiuta ke configure ʻaki hono letioó (vakai ki he founga fokotuʻutuʻu ʻo e tuʻo lahi ʻi he konga ki lalo ʻo e peesi fakaikiiki ki he founga ngaue pau).

Ngaahi meʻa ʻoku fie maʻu ke tokangaʻí:

1: Kataki ʻo fakapapauʻi ʻoku tonu ʻa e malohi ʻo e polarity mo e malohi voltage kimuʻa pea toki fakamoʻui ʻa e malohi. Kapau ʻoku laka hake ʻa e voltage ʻi he 5V pe ko e ngaahi vaʻakau lelei mo kovi ʻo e maʻuʻanga ʻuhila ʻoku fehokotaki fulihi, te ne ala fakatupu ha maumau tuʻuloa ki he polokalamá.

2: Don&8217;ʻoua ʻe lomiʻi ʻa e ngaahi konga ʻi mui ʻo e module ʻi he taimi ʻoku ngaue ai, koeʻuhi ke ʻoua naʻa uesia ʻa e ngaue angamaheni ʻa e module.

Fakaleleiʻi ʻa e fakamatala ʻo e ongoʻingofua ʻo e maiká:

ʻE lava ʻe he module ko ʻeni ʻo liliu ʻa e maika’ ongoʻingofua ʻo e maika ʻaki hano fakaleleiʻi ʻa e fakafepaki kovi ʻa e maika preamplifier, koeʻuhí ke feau hono fulihi fakafoʻituitui ʻo e kau fakaʻaongaʻí ki he ngaahi fie maʻu pelepelengesi makehé. Ko e tuʻunga ʻulungaanga mahuʻinga ʻo e fale ngaohiʻanga koloa ʻo e fakafepaki ki he ngaahi fakamatala kovi ʻo e maika preamplifier ko e 82K ohms. ʻOku hanga ʻe hono fakatupulaki ʻo e fakafepaki ko ʻeni ʻo fakatupulaki ʻa e ongoʻingofua ʻo e maika kae holoki ʻe he fakafepaki ko ʻeni ʻa e ongoʻingofua ʻo e maika. Fakatokanga'i ange: ʻOku mau ʻoatu pe ʻa e founga ki hono liliu. Kapau ʻokú ke fie liliu ia, kātaki ʻo toe fakatau mai pea fakaleleiʻi pē ʻe koe. ʻOku makatuʻunga ʻa e uta kotoa pe ʻi he ongoʻingofua kuo ʻosi seti. ʻOku ʻikai ke mau liliu ʻa e ngaahi fakangatangata ki he ongoʻingofua ʻo e kasitoma takitaha.

Founga mo e founga fokotuʻutuʻu ʻo e tuʻo lahi hono fokotuʻutuʻú:

1: USB ki he TTL module mo e founga fehokotakiʻanga ko ʻení

(2): fakahoko ʻa e USB ki he serial port module pea mo e polokalamá hili hono fakahū ʻo e USB ki hono fakahokohoko ʻo e polokalamá ki he komipiutá, tatali ki he fakaʻuli ke fokotuʻu he taimi pe ko ia hili hono fokotuʻu he taimi pe ko ia ʻa e pule ʻo e device ke sio ki he USB ki he TTL module ʻoku fekauʻaki mo e fika ʻo e taulanga ʻoku fakahokohoko
