Compile thiab download tau
Txuas XNUCELO-F103RB rau PC los ntawm USB cable, qhib Serial pab software, teeb COM chaw nres nkoj: 115200, 8N1

Ntaus cov lus txib los sim module raws li cov ntaub ntawv xa rov qab.

Txuas rau RASPBERRY PI

Peb muab ib tug python example rau Raspberry Pi, koj tuaj yeem rub tawm los ntawm wiki
Ua ntej koj siv tus example, koj yuav tsum qhib qhov chaw nres nkoj ntawm Raspberry Pi ua ntej:
Input command ntawm Terminal: Sudo raspi-config
Xaiv: Interfacing Options -> Serial -> Tsis yog -> Yog
Ces reboot.

UART Fingerprint Sensor (C)	Raspberry Pi
VDC	3.3v XNUMX
