◆ RCL_CMD_ADC_NOISE_GET

struct RCL_CMD_ADC_NOISE_GET

ADC noise command.

Command to collect ADC samples from radio.

This command is used to collect ADC samples from the radio. The samples represent noise (random data), and is intended only to be used as input for entropy generation.

If the output buffer is set to NULL, the samples must be read out by the caller before submitting a new RCL command. The location of the samples can always be read from the output-pointer, which will be updated by the RCL-handler in the case where a NULL-pointer is passed.

Data format

The data format of the output is described below

Word	word[31]	word[30..26]	word[25..21]	word[20..16]	word[15]	word[14..10]	word[9..5]	word[4..0]
0	‘0’	IAC2	IAC1	IAC0	‘0’	QAC2	QAC1	QAC0
1	‘0’	IAC5	IAC4	IAC3	‘0’	QAC5	QAC4	QAC3
...
i	‘0’	IAC(3i+2)	IAC(3i+1)	IAC(3i)	‘0’	QAC(3i+2)	QAC(3i+1)	QAC(3i)

Data Fields
RCL_Command	common
uint32_t	numWords	Number of ADC sample words to collect. Range [1..1024]
uint32_t *	output	Buffer for storing ADC samples. NULL: Do not copy samples, but leave them in the LRF RAM. This pointer will be updated by the RCL-handler to point to the location in RAM where the data is stored.
