我正在开发一个 Raspberry Pi 项目。我正在尝试安装 driver package适用于 ACR1251U-A1 NFC 标签。
此软件包需要首先安装 pcsc-lite 软件包。但据我在互联网上搜索后了解到,pcsc-lite 1.8.13 不适用于 Raspbian OS。
我的主管坚持认为 pcsc-lite 1.8.13 应该安装在 Raspberry Pi 上才能使 NFC 标签正常工作。
可以在 Raspbian 上安装它吗?如果是这样,你能帮我怎么做吗?
最佳答案
我能够安装 pcscd
守护程序并使用 pcsc-lite
wrapper in NodeJS在 Raspbian(Linux raspberrypi 3.18.11-v7+ #781 SMP PREEMPT Tue Apr 21 18:07:59 BST 2015 armv7l GNU/Linux
)上使用 Raspberry Pi B+ 和 Raspberry Pi 2。
这里是 full guide of mine project on GitHub 中的需求安装摘录:
Install PC/SC and libnfc (references: nfc-tools, libnfc):
sudo apt-get install pcscd libusb-dev libpcsclite1 libpcsclite-dev dh-autoreconf cd /opt/ sudo wget https://github.com/nfc-tools/libnfc/archive/libnfc-1.7.1.zip sudo unzip libnfc-1.7.1.zip cd libnfc-libnfc-1.7.1/ sudo autoreconf -vis sudo ./configure --with-drivers=all sudo make sudo make install
Additionaly, you may need to grant permissions to your user to drive the device. Under GNU/Linux systems, if you use
udev
, you could use the providedudev
rules. e.g. under Debian:sudo cp /opt/libnfc-libnfc-1.7.1/contrib/udev/42-pn53x.rules /lib/udev/rules.d/
Make sure the NFC reader is properly recognized:
sudo nfc-list
To fix:
error while loading shared libraries: libnfc.so.4: cannot open shared object file: No such file or directory
(reference)echo '/usr/local/lib' | sudo tee -a /etc/ld.so.conf.d/usr-local-lib.conf && sudo ldconfig
If you have kernel version > 3.5, probably
pcscd
and alsonfc-list
will report this error:Unable to claim USB interface (Device or resource busy)
due to the automatic load ofpn533
driver.To read the
pcscd
dameon output you can run it using:pcscd -f -d
- Check which kernel version is installed:
uname -a
Blacklist
pn533
andnfc
drivers (references: Arch Linux wiki Touchatag RFID Reader, nfc-tools forum):sudo nano /etc/modprobe.d/blacklist-libnfc.conf
Add the following lines:
blacklist pn533 blacklist nfc
Disable kernel modules:
modprobe -r pn533 nfc
Restart the
pcscd
daemon:sudo service pcscd restart
关于linux - 是否可以在 Raspbian 操作系统上安装 pcsc-lite 1.8.13?,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/29834202/
