WAVESHARE STM32F205 UART Fingerprint Sensor Manual

ʻO kēia ka mea i hoʻohui pū ʻia me ke ʻano poepoe a pau i loko o hoʻokahi capacitive fingerprint sensor module, ʻaneʻane liʻiliʻi e like me ka pā kui. Mālama ʻia ka module ma o nā kauoha UART, maʻalahi e hoʻohana. ʻO kāna advantage komo pū me 360° Omni-directional verification, fast verification, high stability, low power consumption, etc.
Hoʻokumu ʻia ma kahi kaʻina hana Cortex kiʻekiʻe, i hui pū ʻia me kahi algorithm fingerprinting kālepa palekana kiʻekiʻe, ʻo ka UART Fingerprint Sensor (C) nā hiʻohiʻona e like me ka hoʻopaʻa inoa manamana lima, kiʻi kiʻi, ʻike hiʻohiʻona, hana ʻana a me ka mālama ʻana, ka pili ʻana i ka manamana lima, a pēlā aku. Me ka ʻike ʻole e pili ana i ka algorithm fingerprinting paʻakikī, ʻo ka mea wale nō e pono ai ʻoe e hoʻouna i kekahi mau kauoha UART, e hoʻohui koke iā ia i loko o nā noi hōʻoia fingerprint e koi ana i ka liʻiliʻi a me ka pololei kiʻekiʻe.

HIʻona

E maʻalahi ka hoʻohana ʻana e kekahi mau kauoha maʻalahi, ʻaʻole pono ʻoe e ʻike i kahi ʻenehana manamana lima a i ʻole ke ʻano o ka module inter structure
ʻO ka algorithm fingerprinting kalepa, ka hana paʻa, ka hōʻoia wikiwiki, kākoʻo i ka hoʻopaʻa inoa ʻana i ka manamana lima, ka hoʻohālikelike ʻana i ka manamana lima, hōʻiliʻili i ke kiʻi manamana lima, hoʻouka i ka hiʻohiʻona manamana lima, etc.

ʻIke capacitive sensitive, pā wale i ka puka aniani hōʻiliʻili no ka hōʻoia wikiwiki
ʻO nā lako paʻa i hoʻohui pū ʻia, ka mea hana a me ka sensor i hoʻokahi pahu liʻiliʻi, kūpono no nā noi liʻiliʻi

ʻO ka rim hao hao haiki, wahi hoʻopā nui, kākoʻo iā 360° Omni-directional hōʻoia.
Hoʻokomo ʻia ka sensor kanaka, e hoʻokomo koke ka mea hana i ka hiamoe, a ala aʻe i ka wā e hoʻopā ai, hoʻohaʻahaʻa i ka hoʻohana mana

ʻO ka mea hoʻohui UART ma luna o ka moku, maʻalahi ke hoʻopili ʻana me nā paepae lako e like me STM32 a me Raspberry Pi

KA HOAO

Hoʻoiho i ka polokalamu hoʻāʻo UART Fingerprint Sensor mai wiki
E wehe i ka lako polokalamu a koho i ke awa COM pololei.

Hoao ana

Aia kekahi mau hana i hāʻawi ʻia i ka interface Testing

Helu Ninau
E koho helu, a laila kaomi Hoʻouna. Hoʻihoʻi ʻia ka helu o nā mea hoʻohana a hōʻike ʻia i ka ʻIke Pane interface
Hoʻohui mea hoʻohana
E koho Hoʻohui mea hoʻohana, hōʻoia i Loaʻa ʻelua a ID Auto+1, kaomi i ka ID (P1 a P2) a me ka ʻae (P3), a laila kaomi Hoʻouna. ʻO ka hope, hoʻopā i ka sensor no ka loaʻa ʻana o ka manamana lima.
Holoi mea hoʻohana
E koho i Holoi i ka mea hoʻohana, kaomi i ka ID (P1 a P2) a me ka ʻae (P3), a laila kaomi i ka Send.

Holoi i nā mea hoʻohana a pau
E koho Holoi i nā mea hoʻohana a pau, a laila kaomi i ka Send
Hoʻohālikelike 1: 1
E koho 1:1 Hoʻohālikelike, paʻi i ka ID (P1 a P2) a me ka ʻae (P3), a laila kaomi Hoʻouna.
Hoʻohālikelike 1: N
E koho 1: N Hoʻohālikelike, a laila kaomi Hoʻouna.

…
No nā hana hou aku, e ʻoluʻolu e hoʻāʻo. (ʻAʻole loaʻa kekahi o nā hana no kēia module)

Hoʻopili iā XNUCLEO-F103RB

Hāʻawi mākou i kahi code demo no XNCULEO-F103RB, hiki iā ʻoe ke hoʻoiho mai ka wiki

Nānā: No nā pine, e nānā i ka Ikepili maluna

E hoʻohui i ka UART Fingerprint Sensor (C) iā XNUCLEO_F103RB, a hoʻohui i ka mea polokalamu.
E wehe i ka papahana (demo code) e ka polokalamu keil5
E nānā inā ʻike maʻamau ka polokalamu polokalamu a me ka mea hana

Hoʻopili a hoʻoiho
Hoʻohui XNUCELO-F103RB i ka PC ma ke kelepona USB, wehe i nā polokalamu kōkua Serial, hoʻonohonoho i ke awa COM: 115200, 8N1

Kākau i nā kauoha e hoʻāʻo i ka module e like me ka ʻike i hoʻihoʻi ʻia.

Hoʻopili iā RASPBERRY PI

Hāʻawi mākou i kahi python example no Raspberry Pi, hiki iā ʻoe ke hoʻoiho iā ia mai ka wiki
Ma mua o kou hoʻohana ʻana i ka exampʻAe, pono ʻoe e hoʻā i ka port serial o Raspberry Pi ma mua:
Hoʻokomo kauoha ma Terminal: Sudo raspi-config
Koho: Nā Koho Interfacing -> Serial -> ʻAʻole -> ʻAe
A laila hoʻomaka hou.
