Function Documentation

void hw_exit ( void )

Cleans up the hardware system on shutdown.

This function should be called at the end of the program to perform any necessary cleanup tasks.

Examples:: examples/runtime/gpio/main.c, examples/runtime/infrared/main.c, examples/runtime/led/main.c, examples/runtime/ntp/main.c, examples/runtime/watchdog/main.c, examples/runtime/wificonnect/main.c, and examples/runtime/wifiscan/main.c.

void hw_init ( void )

Initializes the hardware system on startup.

This function must be called at the start of the program to initialize the hardware environment.

Examples:: examples/runtime/gpio/main.c, examples/runtime/infrared/main.c, examples/runtime/led/main.c, examples/runtime/ntp/main.c, examples/runtime/watchdog/main.c, examples/runtime/wificonnect/main.c, and examples/runtime/wifiscan/main.c.

void hw_poll ( void )

Occasional polling function for the hardware system.

This function should be called periodically to allow the hardware system to perform any necessary background tasks.

Examples:: examples/runtime/ntp/main.c, examples/runtime/watchdog/main.c, examples/runtime/wificonnect/main.c, and examples/runtime/wifiscan/main.c.
