    "  machine.Pin(pin) -- get a pin, eg machine.Pin(0)\n"

    "    Pins are numbered board specific, either 0-n, or 'D0'-'Dn', or 'A0' - 'An',\n"
    "    according to the boards's pinout sheet.\n"
    "    Pin IO modes are: Pin.IN, Pin.OUT, Pin.OPEN_DRAIN\n"
    "    Pin pull modes are: Pin.PULL_UP, Pin.PULL_UP_47K, Pin.PULL_UP_22K, Pin.PULL_DOWN, Pin.PULL_HOLD\n"
    "  machine.ADC(pin) -- make an analog object from a pin\n"
    "    methods: read_u16()\n"
    "  machine.UART(id, baudrate=115200) -- create an UART object (id=1 - 8, board-specific)\n"
