Implementation
Configure and control the LED
An LED is toggled by CPU0 and CPU1. Before using the LED, a port pin to which the
LED is connected must be configured during the initialization phase.
› First step is to set the port pin to level "HIGH"; this keeps the LED turned off as a
default state (IfxPort_setPinHigh() function).
›
Second step is to set the port pin to push-pull output mode with the
IfxPort_setPinMode() function.
Depending on the state of the global variable g_turnLEDon, either CPU0 turns the
LED on (IfxPort_setPinlow()) or CPU1 turns it off (IfxPort_setPinHigh()).
The state of the global variable g_turnLEDon is changed by CPU2 every second
using the wait() function from the header Bsp.h.
All functions used to control the port pin are declared in the iLLD header IfxPort.h.
