大自然生命的進化，遵循著『遺傳』與『突變』。觀察近百年科技的發展，也許可說是『突飛猛進』，或恐失於『內省總結』之不足 。無論『漸』與『頓』，及其所『悟』一也。『價值』取捨之道，或當反思前後五百年的『歷史興衰』。於『革故鼎新』之恆常變化裡，確立堅定『不易』之典範。科技護生之旨，在教育、在防未然 、在省思生命之可貴…… 如果說『那一日』不過『某一日』，假使講『那一夜』只是『有一夜』，怕將難保『那悲劇』不再重演的耶 ？？！！

 

 

 

雖說

《Adafruit NFC/RFID on Raspberry PiAdd RFID/NFC read and write to your Pi in an hour!》

仍有參考價值，然而『libnfc』已更新至 1.7.1 版，同時樹莓派的 raspbian 以及核心版本也早不同，就讓我們從軟體安裝開始展開 Adafruit 『PN532 NFC/RFID controller breakout board – v1.6』

的探討︰

 

# libnfc 1.7.1 編譯與安裝
sudo apt-get install libudev-dev
sudo apt-get install libusb-dev

wget https://bintray.com/artifact/download/nfc-tools/sources/libnfc-1.7.1.tar.bz2

tar xjf libnfc-1.7.1.tar.bz2

cd libnfc-1.7.1/

./configure --prefix=/usr --sysconfdir=/etc
make
sudo make install

# 避免 pn532 被誤認為 pn533
sudo nano /etc/modprobe.d/nfc-blacklist.conf

more /etc/modprobe.d/nfc-blacklist.conf

# 檔案內容 
blacklist pn533
blacklist nfc

sudo modprobe -r pn533 nfc
sudo reboot

# nfc-tool Libfreefare 編譯與安裝
sudo apt-get install autoconf automake git libtool libssl-dev pkg-config

git clone https://github.com/nfc-tools/libfreefare.git

cd libfreefare/

autoreconf -vis
./configure --prefix=/usr
make
sudo make install

# 用 USB 轉 RS232 來連接 Adafruit PN532 NFC/RFID controller breakout board 的設定檔

sudo mkdir /etc/nfc
sudo mkdir /etc/nfc/devices.d
sudo nano /etc/nfc/devices.d/pn532_uart_on_rpi.conf
sudo nano /etc/nfc/libnfc.conf 

more /etc/nfc/devices.d/pn532_uart_on_rpi.conf

# 檔案內容
## Typical configuration file for PN532 board (ie. microbuilder.eu / Adafruit) device
name = "Adafruit PN532 board via UART"
connstring = pn532_uart:/dev/ttyUSB0
allow_intrusive_scan = true
log_level = 3

more /etc/nfc/libnfc.conf 

# 檔案內容
# Allow device auto-detection (default: true)
# Note: if this auto-detection is disabled, user has to set manually a device
# configuration using file or environment variable
allow_autoscan = true

# Allow intrusive auto-detection (default: false)
# Warning: intrusive auto-detection can seriously disturb other devices
# This option is not recommended, user should prefer to add manually his device.
#allow_intrusive_scan = false

# Set log level (default: error)
# Valid log levels are (in order of verbosity): 0 (none), 1 (error), 2 (info), 3 (debug)
# Note: if you compiled with --enable-debug option, the default log level is "debug"
#log_level = 1

# Manually set default device (no default)
# To set a default device, you must set both name and connstring for your device
# Note: if autoscan is enabled, default device will be the first device available in device list.
#device.name = "microBuilder.eu"
#device.connstring = "pn532_uart:/dev/ttyUSB0"
