Function Documentation

ledGreen()

void ledGreen ( bool  on )

inline

Turns the green user LED (TX) on or off.

Parameters

on	1 to turn on the LED, 0 to turn it off.

The green user LED is pin PD5, which is also known as TXLED. The Arduino core code uses this LED to indicate when it receives data over USB, so it might be hard to control this LED when USB is connected.

Definition at line 57 of file Zumo32U4.h.

ledRed()

void ledRed ( bool  on )

inline

Turns the red user LED (RX) on or off.

Parameters

on	1 to turn on the LED, 0 to turn it off.

The red user LED is on pin 17, which is also known as PB0, SS, and RXLED. The Arduino core code uses this LED to indicate when it receives data over USB, so it might be hard to control this LED when USB is connected.

ledYellow()

void ledYellow ( bool  on )

inline

Turns the yellow user LED on pin 13 on or off.

Parameters

on	1 to turn on the LED, 0 to turn it off.

Definition at line 45 of file Zumo32U4.h.

usbPowerPresent()

bool usbPowerPresent ( )

inline

Returns true if USB power is detected.

This function returns true if power is detected on the board's USB port and returns false otherwise. It uses the ATmega32U4's VBUS line, which is directly connected to the power pin of the USB connector.
