- clone from github
? utils git:(master) ? git clone https://github.com/nfc-tools/libnfc.git
- config and make

detect nfc facility
? utils git:(master) ? sudo nfc-list #will not find it
? utils git:(master) ? sudo LIBNFC_LOG_LEVEL=3 nfc-list
info libnfc.config Unable to open file: /usr/local/etc/nfc/libnfc.conf
debug libnfc.config Unable to open directory: /usr/local/etc/nfc/devices.d
debug libnfc.general log_level is set to 3
debug libnfc.general allow_autoscan is set to true

nfc-scan-device uses libnfc libnfc-1.7.1-199-ga9af192
debug libnfc.driver.arygon Trying to find ARYGON device on serial port: /dev/ttyUSB0 at 9600 baud.
debug libnfc.bus.uart Serial port speed requested to be set to 9600 baud.
...
so I create /usr/local/etc/nfc/libnfc.conf
device.name = "my-nfc-chip"
device.connstring = "pn532_uart:/dev/ttyUSB0"
then I use nfc-list
? utils git:(master) ? sudo nfc-list
nfc-list uses libnfc libnfc-1.7.1-199-ga9af192
NFC device: my-nfc-chip opened
