class robovero.lpc17xx_pinsel.PINSEL_CFG_Type(**kwargs)

Bases: robovero.internals.cstruct

Pin configuration structure.

  • Portnum: Port Number, should be PINSEL_PORT_x, where x should be in range

    from 0 to 4

  • Pinnum: Pin Number, should be PINSEL_PIN_x, where x should be in range from 0

    to 31

  • Funcnum: Function Number, should be PINSEL_FUNC_x, where x should be in range

    from 0 to 3

  • Pinmode: Pin Mode, should be:

    • PINSEL_PINMODE_PULLUP: Internal pull-up resistor
    • PINSEL_PINMODE_TRISTATE: Tri-state
    • PINSEL_PINMODE_PULLDOWN: Internal pull-down resistor

  • OpenDrain: OpenDrain mode, should be:

    • PINSEL_PINMODE_NORMAL: Pin is in the normal (not open drain) mode
    • PINSEL_PINMODE_OPENDRAIN: Pin is in the open drain mode
  • ptr: LPC1769 memory address where structure is stored. Use this in place of

    the C reference operator (&).

robovero.lpc17xx_pinsel.PINSEL_ConfigPin(PinCfg)
