include Timestamp

Set the timestamp format for the data log entries.

datalogger.includeTimestamp(FlashLogTimeStampFormat.None)

A timestamp value is included as one of the data items in a log entry. You can choose which timestamp format you want for your log entries. Time units are from milliseconds to days. If you don’t want a timestamp, you use this function to set the timestamp to none. If you haven’t changed the timestamp format, the default is milliseconds.

Parameters

• format: the format of the timestamp as time units or none:

  • milliseconds: time is recorded in milliseconds
  • seconds: time is recorded as seconds
  • minutes: time is set as minutes
  • hours: time is recorded in hours
  • days: time is recorded as days
  • none: a timestamp is NOT included with a log entry

Example

Ambient values

Record the temperature and brightness of light near the Calliope mini every minute.

datalogger.includeTimestamp(FlashLogTimeStampFormat.Minutes)
datalogger.setColumns(["temperature", "light"])
loops.everyInterval(60000, function () {
    datalogger.logData([datalogger.createCV("temperature", input.temperature()), datalogger.createCV("light", input.lightLevel())])
})

Random buttons

Randomly record the state of the button presses on the Calliope mini without a timestamp.

datalogger.includeTimestamp(FlashLogTimeStampFormat.None)
datalogger.setColumns(["Button A", "Button B"])
basic.forever(function () {
    datalogger.logData([datalogger.createCV("Button A", input.buttonIsPressed(Button.A)), datalogger.createCV("Button B", input.buttonIsPressed(Button.B))])
    basic.pause(randint(100, 2000))
})
