Sensoro sa menoana ea UART (C)	NUCLEO-F103RB
VDC	3.3V
GND	GND
RX	PA9
TX	PA10
RST	PB5
TSOSANG	PB3

Hlokomela: Mabapi le lithapo, ka kopo sheba ho Sehokedi hodimo

Hokela UART Fingerprint Sensor (C) ho XNUCLEO_F103RB, 'me u hokelle moetsi oa lenaneo.
Bula projeke (khoutu ea demo) ka software ea keil5
Sheba hore na moqapi le sesebelisoa li tsejoa ka mokhoa o tloaelehileng

Kopanya le ho jarolla
Hokela XNUCELO-F103RB ho PC ka thapo ea USB, bula software ea thuso ea serial, seta boema-kepe ba COM: 115200, 8N1

Tlanya litaelo ho mojule oa teko ho latela lintlha tse khutlisitsoeng.

KHOPALA LE RASPBERRY PI

Re fana ka ex pythonample bakeng sa Raspberry Pi, u ka e khoasolla ho tsoa ho wiki
Pele u sebelisa exampLeha ho le joalo, o lokela ho nolofalletsa boema-kepe ba serial ba Raspberry Pi pele:
Taelo ea ho kenya ho Terminal: Sudo raspi-config
Khetha: Likhetho tsa Interfacing -> Serial -> Che -> E
Ebe o qala hape.

Sensoro sa menoana ea UART (C)	Raspberry Pi
