Function Documentation

srxl_decode()

int srxl_decode	(	uint64_t	timestamp_us,
		uint8_t	byte,
		uint8_t *	num_values,
		uint16_t *	values,
		uint16_t	max_values,
		bool *	failsafe_state
	)

Decode SRXL frames

Structure of all SRXL frames Byte[0]: Header 0xA<VARIANT> –> Variant specific header. Variant is encoded in bits 3-0 of header byte. Byte[1] - Byte[N-2]: SRXL variant specific payload Byte[N-1] - Byte[N]: CRC16 over payload and header

Parameters

[in]	timestamp_us	- timestamp in microseconds
[in]	received	byte in microseconds
[out]	num_values	- number of RC channels extracted from srxl frame
[out]	values	- array of RC channels with refreshed information as pulsewidth in microseconds Range: 800us - 2200us
[in]	maximum	number of values supported by pixhawk
[out]	failsafe_state	- true: RC-receiver is in failsafe state, false: RC-receiver is not in failsafe state

Return values

0	success (a decoded packet)
1	no packet yet (accumulating)
2	unknown packet
4	checksum error
