Implementation

Configure and control the LEDs

The LEDs can be switched on/off by controlling the port pins to which they are connected using methods from
the iLLD headers

IfxPort.h

In the setup phase, the port pins connected to the LEDs are configured as push-pull output mode using the
function

IfxPort_setPinMode()

During program execution, the LEDs are switched on and off using the function

IfxPort_setPinState()
