通过 /dev/ttyACM0 的 Arduino 连接不工作

Arduino connection via /dev/ttyACM0 not working

我在 Ubuntu 上通过 Arduino IDE 连接到 arduino UNO 时遇到问题 当然端口是灰色的,但我手动设置了它。 当我尝试上传时,我得到以下信息:

java.lang.NullPointerException thrown while loading
gnu.io.RXTXCommDriver processing.app.SerialNotFoundException: Serial
port '/dev/ttyACM0' not found. Did you select the right one from the
Tools > Serial Port menu?

已安装的软件包:

$ apt list --installed |grep arduino
arduino/bionic,bionic,now 2:1.0.5+dfsg2-4.1 all [installed]
arduino-core/bionic,bionic,now 2:1.0.5+dfsg2-4.1 all [installed]
arduino-mk/bionic,bionic,now 1.5.2-1 all [installed]
$ 

我是拨出组的成员:

$ cat /etc/group |grep marcin
uucp:x:10:marcin
dialout:x:20:marcin
fax:x:21:marcin
audio:x:29:pulse,marcin,timidity
dip:x:30:marcin,marcin
video:x:44:marcin
plugdev:x:46:marcin
marcin:x:1001:

端口 /dev/ttyACM0 是正确的:

$ ls -l /dev/ttyACM0
crw-rw---- 1 root dialout 166, 0 paź 12 20:54 /dev/ttyACM0
$

dmesg output:

$ cat .arduino/preferences.txt |grep serial

serial.parity=N
serial.port=/dev/ttyACM0
serial.stopbits=1

计算机已重新启动,USB 数据线在 IDE 打开和关闭的情况下插拔了几次,没有更多关于如何继续前进的想法。 任何帮助将不胜感激。谢谢。

我按照 NPE 指出的错误解决了问题。

我从 bionic-proposed 存储库安装了 librxtx-java 包

$ sudo apt-get install librxtx-java/bionic-proposed

现在连接正常。谢谢!
