Enumeration Type Documentation

enum wiced_debug_uart_types_t

Debug UARTs.

Used when calling wiced_set_debug_uart.

Enumerator
WICED_ROUTE_DEBUG_NONE	No traces.
WICED_ROUTE_DEBUG_TO_WICED_UART	send debug strings in formatted AIROC HCI messages over HCI UART to ClientControl or MCU
WICED_ROUTE_DEBUG_TO_HCI_UART	send debug strings as plain text to HCI UART, used by default if wiced_set_debug_uart() not called
WICED_ROUTE_DEBUG_TO_DBG_UART	Deprecated.
WICED_ROUTE_DEBUG_TO_PUART	send debug strings as plain text to the peripheral uart (PUART)
WICED_ROUTE_DEBUG_TO_SCB_UART	send debug strings as plain text to the peripheral SCB uart

Function Documentation

void wiced_set_debug_uart

(

wiced_debug_uart_types_t

uart

)

Function wiced_set_debug_uart.

To specify the UART to be used for the debug traces

When configure the BT TRACE route to SCB UART, please following the steps below:

 1. Set debug trace route to SCB UART:
    wiced_set_debug_uart(WICED_ROUTE_DEBUG_TO_SCB_UART);

 2. Select GPIO for SCB UART RX and TX:
    SCB0 only use WICED_GPIO_15 and WICED_GPIO_14
    wiced_hal_gpio_select_function(WICED_GPIO_14, WICED_ARM_SCB0_UART_RXD);
    wiced_hal_gpio_select_function(WICED_GPIO_15, WICED_ARM_SCB0_UART_TXD);

    SCB1 only use WICED_GPIO_19 and WICED_GPIO_18
    wiced_hal_gpio_select_function(WICED_GPIO_18, WICED_ARM_SCB1_UART_RXD);
    wiced_hal_gpio_select_function(WICED_GPIO_19, WICED_ARM_SCB1_UART_TXD);

 3. Set ARM GPIO TX as output:
    SCB0:
    wiced_hal_gpio_configure_pin(WICED_GPIO_15, GPIO_OUTPUT_ENABLE, 0);
    SCB1:
    wiced_hal_gpio_configure_pin(WICED_GPIO_19, GPIO_OUTPUT_ENABLE, 0);

 4. Initialize and configure the SCB uart:
    wiced_hal_puart_init();
    wiced_hal_puart_flow_off();
    wiced_hal_puart_enable_tx();

Parameters

[in]

uart

: UART to be used

Returns

void

void wiced_set_debug_uart_baudrate

(

uint32_t

baudrate

)

Function wiced_set_debug_uart_baudrate.

It configures the value for wiced_set_debug_uart.

Parameters

[in]

baudrate

: baudrate to be used

Returns

void

Note

To reflect the configured baudrate, wiced_set_debug_uart API should be invoked
