Dexcom G6 Diabetic Monitor

This is a simple project that will help Type 1 Diabetics track and monitor their blood sugar levels. First, you add a new Excel file of blood sugar values from the Dexcom Clarity website and put it on GitHub. Once put on Git, the Beagle will do a pull, determine which file is the newest, crunch some numbers to get things like an A1C, then display it on the LCD screen and on the LEDs. Using CronTab, it will also run every 5 minutes, which is the same time interval that the Dexcom website updates.

Install

Clone this repository under the name ECE434_DiabeticMonitor and run:

sudo install.sh reboot

It will configure the crontab to run autorun.sh every five minutes, which in turn runs the primary python script. It also installs the library for the LCD and configures /boot/uEnv.txt to add the device tree on uboot_overlay_addr4.

There should be no need to re-run install.sh at reboot, unless something else has changes the few things that install.sh configures.

Pinout

The LCD is configured on SPI1.

Project Discription

This project is meant to make handling Type 1 Diabetes easier. The project will take a Dexcom.csv file full of blood sugar data, pull the values from this file, and output various data points to the user such as:

Eddie Mannan Dexcom MonitorDate: XX-XX-XXXXTime: XX:XX:XXA1C: XXXCurrent Sugar: XXXHighest Sugar: XXXLowest Sugar: XXXComputation Time: X.XX seconds

The board will also turn on a different colored LED based on the Current Sugar value. If the blood sugar is HIGH (>170), it will turn on the Red, if the blood sugar is GOOD(<170, >70) it will turn Green, and if it is LOW(<70) it will turn Blue. Also, while the project is running and doing its calculations, it will light up the Yellow LED as an assurance that the project is doing something.
