My first project using Seeed Studio XIAO RP2040 and arduino-cli.
blink_seeed_xiao_rp2040.mp4
I recommend to disable VS Code Arduino plugin will not generate IntelliSense(You can compile by arduino-cli and code verification works well even if you skip this step while VS Code C++ Extension stil complains about missing header files).
- see here
- I used
.vscode/arduino.jsonsteps below instead of.vscode/settings.jsonwhich is used at the cited page, but same result I got.
- I used
Since my PC may be different from your environment, plase according to your own environment. Let me show my Environment.
$ uname
Linux # Arch Linux
$ /usr/bin/arduino-cli version
arduino-cli Version: 0.34.2-arch Commit: 963c1a76c9d2a6ea37956a100c0cd8070260208f Date:
$ cat .vscode/settings.json
{
"arduino.commandPath": "arduino-cli",
"arduino.path": "/usr/bin",
"arduino.useArduinoCli": true,
"arduino.additionalUrls": [

# note: It's standalone arduino-cli not a VS Code Arduino Extension bundled one.- Temporary enable automatic IntelliSense generation
-
Open
LEDPikaPika.ino, and run commandArduino: Verifyon command pallete or clicking the button right top corner. After this step,.vscode/c_cpp_properties.jsonwill be created and you will see include error, but we will fix them later. -
Turn off automatic IntelliSense generation again(Do it manually or git restore). Result:
// .vscode/arduino.json
{
"intelliSenseGen": "disable"
}- Find full list of include path. Go to folder where arduino-pico library (referred to as
rp2040) is installed and findlib/platform_inc.txt. You can also find same one at platform_inc.txt(version 3.6.0).
# For my PC, files was placed at here
~/.arduino15/internal/rp2040_rp2040_3.6.0_794e66db9afdfc56/lib/platform_inc.txt
- Copy
platform_inc.txtto somewhere and open it in editor. Replace-iwithprefixbeforeat the start of each lines with the path to them. TheincludePathof.vscode/c_cpp_properties.jsonwhich was generated at above step will give you a hint how to write them.
# Refer to .vscode/c_cpp_properties.json each element is written as absolute path. So we must replace the prefix `-iwithprefixbefore` with path to the folder.
# Copy
$ cp ~/.arduino15/internal/rp2040_rp2040_3.6.0_794e66db9afdfc56/lib/platform_inc.txt /tmp/platform_inc.txt
# For example, username is john
$ sed -i 's/^-iwithprefixbefore/\/home\/john\/.arduino15\/internal\/rp2040_rp2040_3.6.0_794e66db9afdfc56/' /tmp/platform_inc.txt- Update
includePathof.vscode/c_cpp_properties.jsonretaining originalincludePathentries. Save it.
{
"configurations": [
{
"includePath": [
"...", // original (do not remove!)
"/home/john/.arduino15/..." // append
]
}
]
}- Do step 2 again, and make sure that IntelliSense no longer complains.
- nvim-lspconfig
- arduino-config
- arduino/arduino-language-server
- sketch.yaml contains almost all information about this project.
~/.arduino15/platforms- This is default value and can be customized by editing
~/.arduino15/arduino-cli.yaml- That file can be created by
arduino-cli config init
- That file can be created by
I installed arduino-language-server by Mason and add setting to enable the LSP:
require'lspconfig'.arduino_language_server.setup{}See h: lspconfig-server-configurations for more information.
How to prepare files from scratch to setup a project like this repo.
Initialization:
$ arduino-cli sketch new LEDPikaPika
Sketch created in: /path/to/LEDPikaPika
$ cd $_
$ tree
.
└── LEDPikaPika.ino
1 directory, 1 fileAdd board:
arduino-cli core install --additional-urls https://github.com/earlephilhower/arduino-pico/releases/download/global/package_rp2040_index.json rp2040:rp2040
This command downloads and place rp2040 code at
~/.arduino15/packages/rp2040/hardware/not at~/.arduino15/internal.
First compilation without sketch.yaml:
$ arduino-cli compile --only-compilation-database -b rp2040:rp2040:seeed_xiao_rp2040 --dump-profile .
Used platform Version Path
rp2040:rp2040 3.6.0 /home/john/.arduino15/packages/rp2040/hardware/rp2040/3.6.0
profiles:
seeed_xiao_rp2040:
fqbn: rp2040:rp2040:seeed_xiao_rp2040
platforms:
- platform: rp2040:rp2040 (3.6.0)
platform_index_url: https://github.com/earlephilhower/arduino-pico/releases/download/global/package_rp2040_index.json
After compilation copy profiles paste to sketch.yaml:
+profiles:
+ seeed_xiao_rp2040:
+ fqbn: rp2040:rp2040:seeed_xiao_rp2040
+ platforms:
+ - platform: rp2040:rp2040 (3.6.0)
+ platform_index_url: https://github.com/earlephilhower/arduino-pico/releases/download/global/package_rp2040_index.jsonAnd set default_profile:
platform_index_url: https://github.com/earlephilhower/arduino-pico/releases/download/global/package_rp2040_index.json
+default_profile: seeed_xiao_rp2040After these configuration, the compile sequence become very simple:
arduino-cli compile .
Uploading sequence also become simple:
arduino-cli upload -p /dev/ttyACM0 .
Upload after compile in one command:
arduino-cli compile -u -p /dev/ttyACM0 .
When after cloning this repo and run arduino-cli compile . (with no ~/.arduino15 for the first time?), arduino-cli downloads platform codes into ~/.arduino15/internal instead of ~/.arduino15/platforms.
