v1.6
c186fa4

This release includes several improvements and new features:

  • The sensor readings can now be streamed to the serial TX pin (in addition to being displayed in the terminal and logged to SD card)
    • You can enable this feature using Menu 4 (Configure Serial Logging) Option 2
    • The baud rate is set using Menu 4 Option 4 (the serial pin and the terminal have separate baud rates)
    • When serial output is enabled, analog logging on pin 12 is disabled
    • This resolves issue #32
  • A new SD Card File Transfer menu has been added
    • You can access this by selecting Menu s from the Main Menu
    • You can now:
      • List the files on the SD card using ls or dir
      • Delete a single file using del filename or rm filename
      • Type the contents of a single file to the terminal using type filename or cat filename
      • Copy or transfer a single file to the serial TX pin using ss filename
      • Transfer a single file or all files to the terminal using the ZMODEM protocol
        • Tera Term supports ZMODEM. Select File\Transfer\ZMODEM\Receive from the pull-down menus
        • To transfer a single file: sz filename
        • To transfer all files: sz *
    • The ZMODEM start delay can be changed using Menu 4 Option 3
    • The code is based on ecm-bitflipper's Arduino_ZModem
    • This resolves issue #33
  • The serial and data log files are now timestamped with create and access timestamps
    • By default, the access timestamp is only set when the file is closed
    • You can enable frequent file access timestamps using Menu 1 Option 11
      • Frequent timestamping requires additional SD card writes and may cause problems when logging data at high rates
  • An additional delay allows the IMU to start cleanly after being powered down during sleep
    • This resolves issue #18
  • The measurement count no longer resets when the menus are opened
    • This resolves issue #31
  • Low battery detection is now supported on the v10 (red) version of the OLA
    • Automatic powerDown on low battery can be enabled using Menu 7 Option 4
    • The low battery threshold voltage can be set using Menu 7 Option 5
  • The code now defines a power-on delay for each sensor type
    • When waking from sleep, the code will now wait until attempting to begin 'slow' sensors like the SCD30 or a u-blox module
    • You can extend/override the power-on delay by selecting Menu 6, then Configure Qwiic Settings , then Option 3
    • You can extend the delay to a maximum of 60 seconds, which is more than enough time to allow a u-blox module to establish a fix before the data is read
    • This resolves issue #5
  • Instead of logging data at regular time intervals, data logging can now also be triggered via Pin 11
    • This new feature is enabled via Menu 1 Option 12
    • Data logging can be triggered on falling or rising edges (Menu 1 Option 13)
    • When triggering is enabled, the normal log rate settings are ignored
    • Pin 11 generates an interrupt rather than being polled, allowing fast events to trigger logging
    • This resolves issue #36
  • The IMU temperature reading has been corrected
    • This resolves issue #28
