bool isPulseValid	(	const struct rx_config *	conf,
		uint16_t	pulseDuration
	)

bool rx_flight_channels_valid

(

struct rx *

self

)

Returns true if channels 0-3 are active.

int16_t rx_get_channel	(	struct rx *	self,
		uint8_t	chan
	)

Get channel value. Returns interval [rx_min_usec;rx_max_usec].

uint8_t rx_get_channel_count

(

struct rx *

self

)

uint16_t rx_get_refresh_rate

(

struct rx *

self

)

uint16_t rx_get_rssi

(

struct rx *

self

)

bool rx_has_signal

(

struct rx *

self

)

RX has signal if at least one channel is healthy.

void rx_init	(	struct rx *	self,
		const struct system_calls *	system,
		const struct config *	config
	)

bool rx_is_healthy

(

struct rx *

self

)

RX is healthy if all channels are healthy.

void rx_resume_signal

(

struct rx *

self

)

void rx_set_type	(	struct rx *	self,
		rx_type_t	type
	)

changes the receiver type (determines what system calls the rx system will use to get receiver data)

Sets receiver type.

uint8_t serialRxFrameStatus

(

struct rx *

self

)

FIXME: Each of the xxxxFrameStatus() methods MUST be able to survive being called without the corresponding xxxInit() method having been called first.

This situation arises when the cli or the msp changes the value of rxConfig->serialrx_provider

A solution is for the ___Init() to configure the serialRxFrameStatus function pointer which should be used instead of the switch statement below.

Here is the call graph for this function:

void serialRxInit

(

struct rx_config *

rxConfig
