Detailed Description

Defines a driver to facilitate interfacing with the Debug UART hardware to send bytes or a stream of bytes over the Debug UART hardware.

Typical use-cases involve printing messages over UART/RS-232.

Function Documentation

wiced_bool_t wiced_hal_duart_init	(	wiced_bt_gpio_numbers_t	tx_pin,
		wiced_bt_gpio_numbers_t	rx_pin,
		uint32_t	baudrate
	)

Initialize the Debug UART interface.

Parameters

tx_pin	- target transmit pin
rx_pin	- target receive pin
baudrate	- target baud rate

Returns

WICED_TRUE if Success

Notices: 1. If the tx_pin belongs to the LHL GPIO (<= WICED_P39), the ARM GPIO 6 (WICED_GPIO_06) cannot be set to other purpose.

1. If the rx_pin belongs to the LHL GPIO (<= WICED_P39), the ARM GPIO 7 (WICED_GPIO_07) cannot be set to other purpose.
2. The receive function is not supported now.

void wiced_hal_duart_write	(	uint8_t *	p_buf,
		uint16_t	len
	)

Transmit data via Debug UART.

Parameters

p_buf	- data to be sent
len	- length of data in bytes

Returns

none
