Functions
bool	Waps_uart_init (new_frame_cb_f frame_cb, uint32_t baud, bool flow_ctrl, void *tx_buffer, void *rx_buffer)
	WAPS UART initialize, after this, WAPS UART is ready to transmit and receive serial data.
void	Waps_uart_powerReset (void)
	Power config. Disable UART auto-powering on Sinks and LL Nodes.

Function Documentation

Waps_uart_AutoPowerOff()

void Waps_uart_AutoPowerOff

(

void

)

Disable automatic RX power.

Waps_uart_AutoPowerOn()

void Waps_uart_AutoPowerOn

(

void

)

Enable automatic RX power.

Waps_uart_clean()

void Waps_uart_clean

(

void

)

Clean waps from old data.

Waps_uart_flush()

void Waps_uart_flush

(

void

)

Flush UART module TX buffer. Waits for operation (pend) to complete before returning.

Waps_uart_init()

bool Waps_uart_init	(	new_frame_cb_f	frame_cb,
		uint32_t	baud,
		bool	flow_ctrl,
		void *	tx_buffer,
		void *	rx_buffer
	)

WAPS UART initialize, after this, WAPS UART is ready to transmit and receive serial data.

Parameters

frame_cb	Mandatory callback for upper layer notification about a valid looking frame
baud	Baudrate for communication
flow_ctrl	Is flow control to be used or not
tx_buffer	Memory block for transmissions
rx_buffer	Memory block for receptions

Returns

True if successful, false otherwise

Waps_uart_keepPowerOn()

void Waps_uart_keepPowerOn

(

void

)

Keep power on (receiver is receiving)

Waps_uart_powerExec()

uint32_t Waps_uart_powerExec

(

void

)

Callback task for power manager.

Waps_uart_powerOff()

void Waps_uart_powerOff

(

void

)

Grafecully power down UART, if autopower-feature is used.

Waps_uart_powerReset()

void Waps_uart_powerReset

(

void

)

Power config. Disable UART auto-powering on Sinks and LL Nodes.

Waps_uart_send()

bool Waps_uart_send	(	const void *	buffer,
		uint32_t	size
	)

WAPS UART send, send a block of data via serial port Automatically applies SLIP encoding to data and appends CRC.

Parameters

buffer	Pointer to memory block for transmit
size	Amount of data in bytes to send

Waps_uart_setIrq()

void Waps_uart_setIrq

(

bool

state

)

Set indication that something is pending.

Parameters

state

True means that something is pending, false that queues are empty

Note

This reflects only the WAPS frame buffers state, IRQ pin state is finally determined by the SPI interface itself
