Flash and run

1. Plug a 2x10 mini adapter into the Daisy Seed with the red stripe facing up towards the white stripe.

2. Connect the other end to a ST-Link or similiar programmer.

3. Start openocd in one terminal:

    cd /path/to/{{project-name}}
    /path/to/openocd
   

4. Run program in another terminal:

    cd /path/to/{{project-name}}
    cargo build
   
    # some programmers may need you to hit the reset button on the Daisy Seed at this point
   
    cargo run
   

ITM logging support (optional)

1. Enable the "log-itm" feature for the daisy_bsp create in Cargo.toml:

   daisy_bsp = { version = "0.3.0", features = ["log-itm"] }
