Arduino Support for Visual Studio Code

The Arduino extension makes it easy to build and upload Arduino sketch from Visual Studio Code.

• C++ intellisense with cpptools
• Build/Compile sketch with VSCode
• Upload sketch
• Custom uploader support

Features

Integrate the Arduino IDE for VSCode, with this extension, you can edit sketch with intellisense and use the VSCode to compile and upload to your board.

Requirements

• Recent version of Arduino IDE (at least v1.8.x)
• ms-vscode.cpptools extension for C++ intellisense to work
• A Arduino compatiable board to develop. :)
• Manually associate the .ino file to C++ if needed.

Extension Settings

This extension contributes the following settings:

• arduino.idePath: Specify where the Arduino IDE is (Note: Absolute path only).
• arduino.libraryPath: Sprcifies the serial port borad are connected (Note: Absolute path only).
• arduino.fqbn: Specifies the borad type to use (fully qualified board name).
• arduino.serialPort: Specifies the serial port borad are connected. (Windows: COMx, macOS: /dev/cu./dev/cu.usbmodemxxxx, Linux: /dev/ttyUSBxx)
• arduino.warnPercentage: set to blah to do something
• arduino.compileOptions: Additional options for compile the sketch
• arduino.uploader: Custom uploader for extra board types
• arduino.uploadOptions: Additional options for avrdude upload the compiled sketch
• arduino.partno: Specify AVR device (Upload only)
• arduino.programmer: Specify programmer type (Upload only)
• arduino.baudrate: Override RS-232 baud rate (Upload only)
• arduino.verbose: Use verbose output when build and upload.

Please note, every path here should be absolute path, relative path won't work.

Custom uploader support

If you need to develop on a custom board like NodeMCU, you need to specify the uploader esptool to arduino.uploader option. Once you set the uploader, the extension will use the arduino.uploadOptions with this uploader. And there are some replacement arguments for the uploadOptions:

• $BAUDRATE will be replaced to the baudrate option
• $SERIALPORT will be replaced to the serial port option
• $TARGET will be replaced to the compiled object, (Note, this option contains no bin or hex extension).

For example:

"arduino.fqbn": "esp8266:esp8266:nodemcu:CpuFrequency=80,UploadSpeed=115200,FlashSize=4M3M",
"arduino.uploader" : "/Users/steve/Library/Arduino15/packages/esp8266/tools/esptool/0.4.9/esptool",
"arduino.uploadOptions": "-vv -cd ck -cb $BAUDRATE -cp $SERIALPORT -ca 0x00000 -cf $TARGET.bin",
"arduino.compileOptions": "-hardware /Users/steve/Library/Arduino15/packages -tools /Users/steve/Library/Arduino15/packages -prefs=runtime.tools.esptool.path=/Users/steve/Library/Arduino15/packages/esp8266/tools/esptool/0.4.9 -prefs=runtime.tools.xtensa-lx106-elf-gcc.path=/Users/steve/Library/Arduino15/packages/esp8266/tools/xtensa-lx106-elf-gcc/1.20.0-26-gb404fb9-2 -prefs=runtime.tools.mkspiffs.path=/Users/steve/Library/Arduino15/packages/esp8266/tools/mkspiffs/0.1.2"

You can get these options by enable verbose output when compile/upload in Arduino IDE.

Known Issues

Linux support not tested, but it should work. Custom uploader not tested, because I don't have those board to test.
