linux - 串口不可用arduino

Question

尝试将代码上传到 arduino，但无论是在 Arduino IDE 还是 Arduino Create 中，都在上传时返回此错误。在 Linux Tara(mint 19 cinnamon)上运行。

./opt/arduino-builder/arduino-builder -compile -core-api-version 10611 -hardware opt/arduino-builder/hardware -hardware ./opt/cores -tools opt/arduino-builder/tools -tools ./opt/tools -built-in-libraries opt/libraries/latest -logger humantags -fqbn arduino:avr:mega:cpu=atmega2560 -build-cache /tmp -build-path /tmp/716441957/build -verbose -libraries /tmp/716441957/custom -libraries /tmp/716441957/pinned /tmp/716441957/sketch_oct8a

Sketch uses 8280 bytes (3%) of program storage space. Maximum is 253952 bytes.

Global variables use 443 bytes (5%) of dynamic memory, leaving 7749 bytes for local variables. Maximum is 8192 bytes.

Answer 1

1#首先，检查 IDE 中的端口。在 Arduino 工具->端口如果端口被隐藏或者你不能将光标移到它上面，那么在你的终端中运行这个命令。如果一切正常，那么跳过这个并继续第二部分。

sudo apt-get install librxtx-java -y

sudo usermod -aG dialout $USER 

sudo apt-get install gnome-system-tools

2#
在此之后再次检查第一种方法。如果它不起作用，则运行此命令

ls -l /dev/ttyACM*
sudo usermod -a -G dialout <username>
