  1. > Starting a new Arduino project with avrdude

    > Starting a new project is made simpler with the cargo-generate crate. Simply run the following commands consecutively to create a new project:

    > cargo install cargo-generate

    where? run the commands *where* ?

  2. > Alternatively, you can run the command below to install the libudev-sys crate:

    ^ This tripped me up big-time! If you install libudev-sys via apt you must NOT put the dependency in cargo or it will break your build. I spent about and hour trying to fix this before I re-read the instructions and actually paid attention to the word “alternatively”.

  3. Setting the USB-Port under Windows isnt mentioned here unfortunately. I had to try this a bit and looked for how you list devices under windows:

    “`Get-PnpDevice -PresentOnly | Where-Object { $_.InstanceId -match ‘^USB’ } | Format-List“`
    in powershell gets you something. You have to look through your USB devices and find where the Microcontroller is located, and then put in the port like this in the cargo\config.toml file (as mentioned in the ravedude repo):

    “`runner = “ravedude uno -cb 57600 -P COM3″“`

    COM3 here is where the USB-Port showed up on my machine, uno is the target microcontroller, cb appears to be some sort of datalink speed (should be preset).

    Using ravedude it is possible to simply use cargo run and just flashing the code on the uno which is very neat.
