wispr_pi

Raspberry Pi to WISPR interfacing scripts

Setup

1. Git clone this repo to the /home/pi directory on the WISPR's Raspberry Pi

git clone https://github.com/jmcvey3/wispr_pi.git
cd wispr_pi
git submodule update --init --remote

2. Navigate to 'blue_robotics_ms5837' (pressure sensor) and install:

cd /home/pi/wispr_pi/pressure_sensor/blue_robotics_mw5837
sudo pip install -e .

3. Use the backup crontab ('crontab.bak') and restore the root crontab

sudo crontab /home/pi/wispr_pi/config_files/crontab.bak

The crontab is set to start recording pressure sensor data on boot, as well as to send data to backup every 5 minutes.

4. If using AWS S3 to store data in the cloud, please pip install boto3 and follow the instructions in "How to Install AWS-CLI on rPi.pdf" to set up S3 access keys.

5. Reboot and ensure a pressure sensor log is recorded in /home/pi/wispr_pi/PressureSensor/logs

The following steps are related to those listed in in wispr_rpi.docx

6. First install support for exFAT on your RPi using the following commands:

sudo apt-get update
sudo apt-get install exfat-fuse exfat-utils 

7. Navigate to the boot configuration file (sudo nano /boot/config.txt) and add the following lines (See config_files/boot_config.txt for a backup file):

# Enable 2nd SD card using the custom overlay (disables wifi)
dtparam=sdio_overclock=25
dtoverlay=sdio,poll_once=off

# Enable UART communication for the wispr
enable_uart=1
