Function Documentation

int rt_exit

(

void

)

Stops the test application and releases resources.

Return values:

	0	Success.
	-1	Failure.

References _test_config::task, _test_config::telem_buf, and _test_config::telem_pkt.

int rt_init

(

unsigned short

addr

)

Initializes the test application. The driver is initialized and a the RT polling task is started.

Parameters:

addr

The remote terminal address.

Return values:

	0	Success.
	-1	Failure.

static void rt_pkt_cmd_rx

(

unsigned char *

cmdPkt

)

[static]

Listens for telecommand receive packets arriving at the remote terminal. The SC broadcast telecommands (APID=0x701) are discarded. The communications test diagnostic telecommands (APID=0x646) are parsed and the appropriate telemetry response actions taken. The rececption of any other telecommands is considered an error condition.

Parameters:

cmdPkt

A pointer to the telecommand packet buffer.

Referenced by rt_poll().

static void rt_pkt_diag

(

unsigned char *

cmdPkt

)

[static]

Handles diagnostics communications test telecommands (func code = 0).

Parameters:

cmdPkt

A pointer to the telecommand packet buffer.

static void rt_pkt_fill	(	unsigned char *	pkt,
		unsigned short	patSelect,
		unsigned short	patLength,
		unsigned short	respLength
	)			[static]

Fills in the response data for a communication test telemetry packet.

Parameters:

	pkt	A pointer to the telmetry packet buffer.
	patSelect	The pattern select code.
	patLength	The pattern length value.
	respLength	The response length value.

static void rt_pkt_hkp

(

void

)

[static]

Generates HKP telemetry packets. If a requested HKP communications test response is outstanding, one HKP telemetry packet is delivered.

static void rt_pkt_sc

(

unsigned char *

cmdPkt

)

[static]

Handles diagnostics SC broadcase telecommands.

Parameters:

cmdPkt

A pointer to the telecommand packet buffer.

Referenced by rt_pkt_cmd_rx().

static void rt_poll

(

void

)

[static]

Test application polling task. Constantly polls the RT for new events. For this test telemetry events are ignored and all telecommand input is discarded.

Return values:

	0	Success.
	-1	Failure.

int rt_start

(

Starts the remote terminal.

Return values:

	0	Success.
	-1	Failure.

References _test_config::rt, rt_poll(), RT_POLL_NAME, RT_POLL_PRI, SUMT_rtPollStart(), and _test_config::task.

int rt_stop

(

void

)

Stops the remote terminal.

Return values:

	0	Success.
	-1	Failure.
