• add the Arduino extension
• the vscode arduino extension serial monitor in ubuntu 22.04 doesn't seem to work. Use miniterm.py inside the vscode terminal instead
• for some reason new code is not loaded in through ISP unless the code is verified first
  • you can automate some of this with extension Commands
    • example: inside global (not the workspace (???) ) settings.json:

    "commands.commands": {
        "sequence": [
"workbench.action.terminal.kill",
"arduino.verify",
"arduino.cliUploadUsingProgrammer",
],
}

from there you can assign it a hotkey. I assigned it to <META>i
