Okay. Sorry about this, but could I ask for a little more help with the doppler board file?

The one charlotte gave me said:
```
        # PCB button1, button2
        Resource("button", 0, Pins("2 3", dir="i"),
                 Attrs(IO_STANDARD="SB_LVCMOS")),
        Resource("button", 1, Pins("3", dir="i"),
                 Attrs(IO_STANDARD="SB_LVCMOS")),```
