USB-connected µFR Nano Online NFC RFID Reader Writer on the Raspberry Pi

USB-connected µFR Nano Online NFC RFID Reader Writer on the Raspberry Pi To connect and run the µFR Nano Online reader plugged into the Raspberry Pi USB port, follow the instructions below: 1) USB-CONNECTED µFR NANO ONLINE NFC READER INSTALLATION All µFR series devices require FTDI drivers for USB communication. This also applies to the µFR Nano Online NFC reader if it is used as a standard USB device. If you have no FTDI drivers installed on your installed Raspberry Pi, please follow the manual for the FTDI drivers installed on the Linux-based platforms. This article is also available in our Knowledge Base. Important notice: Before you proceed with the µFR Nano Online implementation, make sure you grant the USB PORT access permission to the local user (the script is available in our GitLab projects repository). Once you have the FTDI drivers installed with your USB-connected NFC reader, you will be able to open the port and establish communication with the device by the ReaderOpen function provided by the ufr library. Important notice: The recommended library for the Raspberry Pi is the 64-bit aarch64. However, there are some known problems with aarch64 on a Raspberry Pi 4 with 8 GB...

Configure Raspbian for Raspberry Pi 3 to use Digital Logic shield with µFR Reader RS232

Configure Raspbian for Raspberry Pi 3 to use Digital Logic shield with µFR Reader RS232 Preface Digital Logic shield with µFR Reader RS232 The Shield ​is​​ peace​​ of​​ hardware​​ for ​​simplified ​​interconnection ​​between ​​µFR Reader RS232 devices,​ such as the µFR Nano RS232 and µFR Classic CS RS232 reader model, ​​and any ​​Raspberry​ ​Pi ​​version​.  DL​shield ​​uses​ ​pins ​​8 (GPIO14) ​​and ​​10​ ​(GPIO15)​​ of​​ the ​​GPIO ​​header ​​for ​​UART​ ​communication ​​and pins ​​16​ (GPIO23)​ for​​ resetting​​ the ​​µFR Reader. GPIO​ serial ​​port ​​(​mini​-UART)​ is ​​​disabled ​​by ​​default​. It has to be ​​enabled ​for ​​the device’s full functionality. uFCoder ​library ​​version ​​4​.2.7 ​and ​​later ​​support ​​DL​​ Shields ​​on ​​Raspbian​. Caution The RPi’s serial port (and all other GPIO’s) operate at 3.3V power only. Connecting them to a 5V source will damage your RPi.
