Phukusi la ST UM2766 X-LINUX-NFC5 la Kukulitsa NFC/RFID Reader

Mawu Oyamba

Phukusi lokulitsa pulogalamu ya STM32 MPU OpenSTLinux likuwonetsa momwe mungapangire kulumikizana kwa NFC/RF pamakina wamba a Linux pogwiritsa ntchito Radio Frequency Abstraction Library (RFAL). Dalaivala wamba wa RFAL amawonetsetsa kuti ntchito yogwiritsa ntchito ndi pulogalamu yogwiritsira ntchito ikugwirizana ndi ST25R NFC/RFID yowerenga IC.
Phukusi la X-LINUX-NFC5 limalowetsa RFAL ku Discovery Kit yokhala ndi STM32MP1 Series microprocessor yomwe ikuyenda Linux kuyendetsa kutsogolo kwa ST25R3911B NFC pa bolodi yakukulitsa ya STM32 Nucleo. Phukusili likuphatikizapo ngatiample application kukuthandizani kumvetsetsa mitundu yosiyanasiyana ya NFC tags ndi mafoni othandizira P2P.
Khodi yoyambira idapangidwa kuti izitha kusuntha pamagawo osiyanasiyana oyendetsera Linux ndipo imathandizira zigawo zonse zapansi ndi ma protocol ena apamwamba a ST25R ICs kuti azitha kulumikizana ndi RF.
