   1 * Software
   2 ** Dependencies
   3 Install packages using these commands:
   4 : $ sudo apt install python-smbus  # Needed for bmp388.py
   5 ** BMP388 Pressure sensor
   6 The following command will download a repository containing a python
   7 script that can pull pressure data from the BerryGPS-IMU v3.5's BMP388
   8 : git clone https://github.com/getelectronics/PIBits.git

  12 - I ordered another two Raspberry Pi Zero W's and another BerryIMU-GPS.
  13
  14 - I think I found the problem with the pressure sensor. According to a
  15   2020-03-12 post by johnmark at
  16   https://ozzmaker.com/forums/topic/temp-barometer/ , the BerryIMU-GPS
  17   version 3.5 uses BMP388, not BMP280. johnmark posted a link to a
  18   python script that works for the BMP388 pressure sensor at:

  22 - I have downloaded this PIBits git repository to jalrasaroa-02 and am
  23   testing it now. It works.
  24
  25 - I am checking to see how I can automatically update the clock on
  26   jalrasaora-02 via a network time server. Reading instructions at
  27   https://www.garron.me/en/go2linux/how-to-set-date-and-time-linux.html
  28   .

  30 - I am installing the `ntp` package described here:

  32     https://www.digitalocean.com/community/tutorials/how-to-set-up-time-synchronization-on-debian-10
  33
  34     $ sudo apt-get update && sudo apt-get upgrade -y && sudo apt-get install ntp
  35
  36   - I confirmed that the ntp time synchronization service is running with:
  37
  38     sudo systemctl status ntp
  39
  40 - I am creating a git repository to store executables and setup
  41   instructions for Raspberry Pi Zero W's used for logging:
  42
  43   - Location (GPS WGS84)
  44   - Air pressure (Pa)
  45   - Temperature (°C)
  46   - Direction (magnetic north heading)
