Tusi Taiala

UMAVIEW

Ole mea lea ole fa'apipi'i fa'atasi uma-i-le-tasi capacitive fingerprint sensor module, lea e toetoe a la'ititi pei o se fao ipu. O le module e pulea e ala i tulafono UART, faigofie ona faʻaoga. O lona lumatage aofia ai le 360 ​​° Omni-directional verification, faʻamaonia vave, mautu maualuga, maualalo le faʻaaogaina o le eletise, ma isi.
Faʻavae i luga o le Cortex processor maualuga, tuʻufaʻatasia ma se algorithming fingerprinting pisinisi maualuga, o le UART Fingerprint Sensor (C) o loʻo faʻaalia ai galuega e pei o le lesitalaina o tamatamailima, mauaina o ata, suʻesuʻeina o ata, faʻataʻitaʻiga faʻatupu ma teuina, faʻafetaui tamatamailima, ma isi. A aunoa ma se malamalama e uiga i le algorithm lavelave fingerprinting, pau lava le mea e tatau ona e faia na o le auina atu o ni tulafono UART, ia vave tuʻufaʻatasia i totonu o talosaga faʻamaonia tamatamailima e manaʻomia ai le laʻititi laʻititi ma le maualuga maualuga.

FAAMATALAGA

• Fa'afaigofie ona fa'aoga e nisi o fa'atonuga faigofie, e te le tau iloa so'o se tekonolosi fa'apipi'i tamatamailima po'o le fausaga fa'atasi
• O le algorithm fingerprinting pisinisi, faʻatinoga mautu, faʻamaonia vave, lagolagoina le lesitalaina o tamatamailima, faʻafetaui tamatamailima, aoina ata o tamatamai lima, faʻapipiʻi ata o tamatamai lima, ma isi.
• Capacitive su'esu'ega ma'ale'ale, na'o le pa'i mama i le fa'amalama aoina mo fa'amaoniga vave
• Meafaigaluega e sili ona tu'ufa'atasia, fa'agaioiina ma le fa'alogo i totonu o se tamai pu, suti mo fa'aoga laiti
• U'u u'amea vaapiapi, vaega tele e pa'i i ai, lagolago le 360° fa'atonuga fa'atonuga.
• Faʻapipiʻiina le tagata, o le processor o le a ulufale otometi i le moe, ma ala i luga pe a paʻi atu, faʻaitiitia le mana faʻaaogaina
• I luga ole va'a UART feso'ota'iga, faigofie ona fa'afeso'ota'i ma masini fa'apipi'i pei ole STM32 ma le Raspberry Pi

Afai e te manaʻo e faʻafesoʻotaʻi le module fingerprint i se PC, e tatau ona e faʻatau se tasi UART i le USB module. Matou te fautuaina oe e faʻaaoga Waveshare FT232 USB UART Board (micro) module.
Afai e te manaʻo e faʻafesoʻotaʻi le masini faʻapipiʻi tamatamailima i se laupapa atinaʻe e pei o Raspberry Pi, pe a galue
maualuga o lau laupapa e 3.3V, e mafai ona e faʻafesoʻotaʻi saʻo i le UART ma GPIO pine o lau laupapa. Afai o le 5V, fa'amolemole fa'aopoopo le fa'aliliuga maualuga module/circuity.

• La'u mai le polokalame su'ega UART Fingerprint Sensor mai le wiki
• Tatala le polokalama ma filifili le COM port sa'o.(E na'o le COM1~COM8 e mafai ona lagolagoina e le polokalama, pe afai o le COM port i lau PC o fafo atu o lenei laina, fa'amolemole suia)
• Su'ega

E tele galuega tauave o loʻo tuʻuina atu ile Suʻega suʻega

1. Faitauga Fesili
   Filifili Faitau, ona kiliki lea Auina atu. O le faitau aofaʻi o tagata faʻaoga e toe faʻafoʻi ma faʻaalia i le Faʻamatalaga Tali feso'ota'iga
2. Fa'aopoopo le Fa'aoga
   Filifili Fa'aopoopo le tagata fa'aoga, siaki i Maua Faalua ma ID Auto+1, lolomi le ID (P1 ma P2) ma le faatagaga (P3), ona kiliki lea Auina atu. Mulimuli ane, pa'i masini e maua ai tamatamai lima.

Fa'aaliga: E uiga i pine, fa'amolemole tagai ile Fa'afeso'ota'i luga

1. Fa'afeso'ota'i le UART Fingerprint Sensor (C) ile XNUCLEO_F103RB, ma fa'afeso'ota'i le polokalame
2. Tatala le poloketi (demo code) e le keil5 software
3. Siaki pe iloa lelei le polokalame ma masini
4. Tuufaatasi ma sii mai
5. Faʻafesoʻotaʻi le XNUCELO-F103RB i le PC e ala ile USB cable, tatala polokalame fesoasoani Serial, seti COM port: 115200, 8N1

Fa'atonu poloaiga e su'e le module e tusa ai ma fa'amatalaga na toe fa'afo'i mai.

FESOASOANI I RASPBERI PI

Matou te tuʻuina atu se python example mo Raspberry Pi, e mafai ona e siiina mai le wiki
Ae e te leʻi faʻaaogaina le example, e tatau ona e faʻatagaina le laina telefoni o Raspberry Pi muamua:
Fa'atonuga i luga ole Terminal: Sudo raspi-config
Filifili: Filifiliga Fa'afeso'ota'i -> Fa'asologa -> Leai -> Ioe
Ona toe fa'afou.
