Function Documentation

EPS_calculate_total_fault_count()

int32_t EPS_calculate_total_fault_count

(

EPS_struct_pdu_overcurrent_fault_state_t *

fault_state

)

Sum the total fault count for all channels.

Parameters

fault_state

A pointer to the fault state struct.

Returns

The summed fault count for all channels.

int32_t EPS_calculate_total_pcu_power_input_cW

(

EPS_struct_pcu_housekeeping_data_eng_t *

pcu_data

)

Sum the total solar panel input for all channels.

Returns

Total input of all PCU channels in cW.

Here is the caller graph for this function:

EPS_convert_battery_voltage_to_percent()

float EPS_convert_battery_voltage_to_percent

(

EPS_battery_pack_datatype_eng_t

battery

)

Calculate the current EPS battery voltage from a PBU telemetry struct.

Parameters

battery

Telemetry struct

Returns

Battery percentage, as a float. Nominally, the battery percentage is between 0 and 100. However, the battery percentage can exceed 100% if the battery voltage is above the maximum voltage, and can be less than 0% if the battery voltage is below the minimum voltage.
