Function Documentation

uint32_t board_buttons

(

void

)

Get the current state of the buttons on the board.

Returns

Bitmask where a '1' means active (pressed), a '0' means inactive.

void board_leds	(	uint32_t	on_mask,
		uint32_t	off_mask
	)

Turns on and off leds on the board.

Parameters

[in]	on_mask	Bitmask for LED's numbers is turning ON
[out]	off_mask	Bitmask for LED's numbers is turning OFF

Note

the on_mask is more priority then off_mask, if an led's number is present on both. It will be turned ON.

uint8_t board_uart_getchar

(

void

)

Get a character input from UART.

Returns

ASCII code of the input character or zero if none.

void board_uart_putchar

(

uint8_t

c

)

Send a character to UART.

Parameters

[in]

c

the character to be sent
