Function Documentation

bool board_gpio_is_usb_msc_mode

(

void

)

Read input line to get if the USB MSC interface should be enabled.

This function will read the BOARD_USB_MODE_ID input line and return true if MSC should be active and false otherwize.

void board_gpio_mcu_reset

(

bool

set

)

Control the reset line to the XMEGA chip.

This function will set or release the reset line to the XMEGA chip depending on the set variable. To hold the XMEGA chip in reset set must be true, to release from reset set must be false.

void board_gpio_set_spi_master_mode

(

bool

master_mode

)

Set SPI I/O lines given the SPI mode.

This function will set the SPI I/O lines in master mode when master_mode is true, the I/O lines will be configured for slave mode otherwize.
