TriCore TC27D Ports(DIO)


HW: ShieldBuddy TC275

  • IfxPort_cfg.h: PORT on-chip implementation data.
  • IfxPort_PinMap.h: PORT I/O map.
  • IfxPort_Io.h: PORT IO details.
  • IfxPort.h: PORT basic functionality.

IfxPort_Io.h

  • The PORT I/O driver provides several functions to easily configure and read pins.
  • The configuration includes input/output, mode, pad driver strength and state. For referencing the pins and their ports a IfxPort_PinMap is available as well.

Examples

Toggling a pin
