High TVe value #3

Closed rohan-tworks closed 4 years ago

rohan-tworks commented 4 years ago

Observation: After running for a duration of ~2 min the display shows high TVe value.

Currently set values: Set TV:400 Displayed TVe: 566 TVi: 413 --> imgA

The machine was then stopped and started again.

It showed similar values.

I then changed the Set TV to various values see if this was happening at other values.

Set TV:350 Displayed TVe:535 TVi:528 Set TV:500 Displayed TVe:627 TVi:528 Set TV:400 Displayed TVe:547 TVi:425

The machine was then rebooted and we performed a zero calibration

Set TV:400 Displayed TVe:566 TVi:401 -->imgB

Possible causes

Additional Data required for next time

This seems to be a calibration method not being called. Was working fine earlier

Steps to reproduce:

  • Turn on the machine
  • Set TV to any value
  • Start the machine
  • Observe the status screen for a few minutes.

@ChoudharyHarshal to work with @rajnikanthsabnekar and send updated file rohan.

ETA : EOD 19th Testing to be done for an hour and observations to be logged

SensorManager - capture_sensor_data : not to stop and start timer , if we stop and start the timer immediately - total acquisition time became bigger value and TVe ,TVi are impacted with lesser values remove logic to use 0.2 older pressure + 0.8 present pressure value for latest calculation store offset for calibration using long Param.

Memory.c - retrieveCalibParamLong to store and retrieve long int values
