WAVESHARE STM32F205 UART Fingerprint Sensor Manual

Le yimodyuli edityaniswe kakhulu engqukuva yonke-kwi-nye yecapacitive ye-fingerprint sensor module, ephantse yancinci njengepleyiti yezikhonkwane. Imodyuli ilawulwa ngemiyalelo ye-UART, kulula ukuyisebenzisa. I-advan yayotagii-es ziquka i-360 ° ukuqinisekiswa kwe-Omni-directional, ukuqinisekiswa ngokukhawuleza, ukuzinza okuphezulu, ukusetyenziswa kwamandla aphantsi, njl.
Ngokusekelwe kwiprosesa ye-Cortex ephezulu, idibaniswe ne-algorithm ye-fingerprinting algorithm yorhwebo, i-UART Fingerprint Sensor (C) ibonisa imisebenzi efana nokubhaliswa kweminwe, ukufumana umfanekiso, ukufunyanwa kweempawu, ukuveliswa kwetemplate kunye nokugcinwa, ukuhambelana kweminwe, njalo njalo. Ngaphandle kwalo naluphi na ulwazi malunga ne-algorithm entsonkothileyo yoshicilelo lweminwe, konke okufuneka ukwenze kukuthumela nje imiyalelo ye-UART, ukuyidibanisa ngokukhawuleza kwizicelo zokuqinisekisa umnwe ezifuna ubungakanani obuncinci kunye nokuchaneka okuphezulu.

IIMBONAKALO

Kulula ukuyisebenzisa ngeminye imiyalelo elula, akufuneki wazi nabuphi na ubuchwephesha boshicilelo lweminwe okanye imodyuli phakathi kwesakhiwo
I-algorithm ye-fingerprinting algorithm, ukusebenza okuzinzile, ukuqinisekiswa okukhawulezayo, isekela ukubhaliswa kweminwe, ukulinganisa iminwe, ukuqokelela umfanekiso weminwe, ukulayisha uphawu lweminwe, njl.

Ubhaqo olunovakalelo olunamandla, chukumisa nje ifestile yokuqokelela kancinci ukuqinisekiswa ngokukhawuleza
I-Hardware idityaniswe kakhulu, iprosesa kunye nenzwa kwi-chip enye encinci, isuti yezicelo zobungakanani obuncinci

Umphetho wentsimbi emxinwa, indawo enkulu echukumisayo, ixhasa ukuqinisekiswa kwe-360 ° Omni-directional
Inzwa edibeneyo yomntu, iprosesa iya kungena ebuthongweni ngokuzenzekelayo, kwaye ivuke xa ichukumisa, ukusetyenziswa kwamandla aphantsi

Vula isofthiwe kwaye ukhethe i-port ye-COM echanekileyo. (I-software inokuxhasa kuphela i-COM1 ~ COM8, ukuba i-COM port kwi-PC yakho ingaphandle kolu luhlu, nceda uyiguqule)

Uvavanyo

Kukho imisebenzi emininzi enikezelweyo kujongano lovavanyo

Umbuzo Bala
Khetha Bala, emva koko ucofe Thumela. Ubalo lwabasebenzisi luyabuyiswa kwaye luboniswe kuLwazi Impendulo ujongano
Yongeza uMsebenzisi
Khetha Yongeza uMsebenzisi, khangela ku Fumana kabini kwaye Auto ID+1, chwetheza isazisi (P1 kwaye P2) kunye nemvume (P3), emva koko ucofe Thumela. Okokugqibela, chukumisa inzwa ukuze ufumane umnwe.
Cima umsebenzisi
Khetha uku Cima umsebenzisi, chwetheza isazisi (P1 kwaye P2) kunye nemvume (P3), emva koko ucofe Thumela.

Cima Bonke Abasebenzisi
Khetha Cima Bonke Abasebenzisi, emva koko ucofe Thumela
Uthelekiso 1:1
Khetha 1: 1 Uthelekiso, chwetheza isazisi (P1 kwaye P2) kunye nemvume (P3), emva koko ucofe Thumela.
Ukuthelekisa 1:N
Khetha 1: N Uthelekiso, emva koko ucofe Thumela.

…
Ngemisebenzi engaphezulu, nceda uyivavanye. (Eminye imisebenzi ayikho kule modyuli)

QHAGAMSHELANA NE-XNUCLEO-F103RB

Sinikezela ngekhowudi yedemo ye-XNCULEO-F103RB, onokuyikhuphela kwi-wiki

i-UART Fingerprint Sensor (C)	I-NUCLEO-F103RB
VDC	3.3V
GND	GND
RX	PA9
TX	PA10
RST	PB5
VUKA	PB3

Phawula: Malunga nezikhonkwane, nceda ubhekisele kwi Ujongano ngaphezulu

Qhagamshela i-UART Fingerprint Sensor (C) kwi-XNUCLEO_F103RB, kwaye uqhagamshele umdwelisi wenkqubo
Vula iprojekthi (ikhowudi yedemo) ngesoftware ye-keil5
Khangela ukuba umdwelisi wenkqubo kunye nesixhobo zibonwa ngesiqhelo

Qokelela kwaye ukhuphele
Qhagamshela i-XNUCELO-F103RB kwiPC ngentambo ye-USB, vula isoftwe yoncedo lweSerial, usete i-COM port: 115200, 8N1

Chwetheza imiyalelo yokuvavanya imodyuli ngokolwazi olubuyisiweyo.

QHAGAMSHELANA NERASPBERRY PI

Sibonelela nge-python example yeRaspberry Pi, unokuyikhuphela kwi-wiki
Ngaphambi kokuba usebenzise i-exampLe, kuya kufuneka wenze izibuko lothotho lweRaspberry Pi kuqala:
Umyalelo wongeniso kwiSitena: Sudo raspi-config
Khetha: Iinketho Zokudibanisa -> Uthotho -> Hayi -> Ewe
Emva koko uqalise kwakhona.

i-UART Fingerprint Sensor (C)	Raspberry Pi
VDC	3.3V
GND	GND
RX	14 (BCM) – PIN 8 (Ibhodi)
TX	15 (BCM) – PIN 10 (Ibhodi)
RST	24 (BCM) – PIN 18 (Ibhodi)
VUKA	23 (BCM) – PIN 16 (Ibhodi)

Qhagamshela imodyuli yeminwe kwiRaspberry Pi
