Function Documentation

read_avg_temperature_cC_from_mpi_data_buffer()

int32_t read_avg_temperature_cC_from_mpi_data_buffer

(

volatile uint8_t *

large_buffer

)

Scan an MPI data buffer, averaging all temperature reports in it.

Parameters

large_buffer

MPI data buffer input.

Returns

Average temperature in 100ths of a degree Celsius (cC). Returns special value -9999 on error.

Variable Documentation

MPI_max_recording_duration_sec

uint32_t MPI_max_recording_duration_sec = 900

Maximum duration for MPI data recording in seconds.

Note

Set this value to 0 (via configuration) to disable the duration limit.

This configuration variable is designed to prevent against an operator failing to schedule a stop telecommand for MPI data recording.

MPI_max_temperature_shutoff_celcius

uint32_t MPI_max_temperature_shutoff_celcius = 60

If the MPI exceeds this value during data recording, recording will be disabled.

Note

Set this value to 0 (via configuration) to disable the temperature shutoff feature.
