Function Documentation

EPS_channel_from_str()

EPS_CHANNEL_enum_t EPS_channel_from_str

(

const char

channel_name[]

)

Converts an EPS channel name to a channel enum.

Parameters

channel_name

A case-insensitive c-string of the channel name (e.g., "mpi"), or a number representing the channel number (e.g., "1" or "16"). Valid string values: "vbatt_stack", "stack_5v", "stack_3v3", "camera", "uhf_antenna_deploy", "gnss", "mpi_5v", "mpi_12v", "boom".

Returns

The corresponding enum value. Returns EPS_CHANNEL_UNKNOWN if no match is found.

EPS_channel_to_str()

char * EPS_channel_to_str

(

EPS_CHANNEL_enum_t

channel

)

Converts channel enum into an ASCII-printable name string.

Parameters

channel

An enum of typedef EPS_CHANNEL_enum_t representing the different channel names of the EPS Ex. EPS_CHANNEL_VBATT_STACK , EPS_CHANNEL_5V_CH2_UNUSED or EPS_CHANNEL_3V3_UHF_ANTENNA_DEPLOY

Returns

Returns a string of the channel name corresponding to the inputted channel enum

EPS_check_status_bit_of_channel()

uint8_t EPS_check_status_bit_of_channel	(	uint16_t	status_bitfield_1,
		uint16_t	status_bitfield_2,
		uint8_t	channel_number )

Takes in the status bitfields of the eps and outputs the status of the given channel number.

Parameters

status_bitfield_1	The status bitfield of channels 0-15.
status_bitfield_2	The status bitfield of channels 16-31.

Returns

0 if the channel is disabled, 1 if the channel is enabled, and 2 if channel number is invalid

Note

If all channels are enabled, the output buffer would be require about 300 bytes.

Here is the caller graph for this function:

EPS_convert_ch_num_to_string_and_append()

uint8_t EPS_convert_ch_num_to_string_and_append	(	char *	response_output_buf,
		uint16_t	response_output_buf_len,
		uint8_t	ch_number )

Convert EPS ch_number to ch_name, then append as a JSON list element to response_output_buf.

Parameters

response_output_buf	The output buffer that will store the string
response_output_buf_len	The total length of the output buffer
ch_number	The channel number of the EPS that will be converted to channel name

Returns

0 when string was properly outputted into the buffer, 1 if the channel number is invalid

EPS_get_enabled_channels_json()

void EPS_get_enabled_channels_json	(	uint16_t	status_bitfield_1,
		uint16_t	status_bitfield_2,
		char *	response_output_buf,
		uint16_t	response_output_buf_len )

Here is the caller graph for this function:

EPS_set_channel_enabled()

uint8_t EPS_set_channel_enabled	(	EPS_CHANNEL_enum_t	channel,
		uint8_t	enabled )

Sets the enabled state of an EPS channel (on or off).

Parameters

channel	The channel to enable or disable.
enabled	0 to disable, >0 to enable.

Returns

0 on success, >0 on failure. Returns 99 if channel is unknown. Propagates the return value from EPS_CMD_output_bus_channel_on/off().
