This application is designed to show all the available pump data in a visual version that mimics the one on iPhone and in tables that can be exported to Microsoft Excel or the Clipboard.
Some data is filtered out by default because I could not see any use for it. You can turn off filters from Options Menu. but performance will suffer.
This project is intended for educational and informational purposes only. It relies on a series of fragile components and assumptions, any of which may break at any time. It is not FDA approved and should not be used to make medical decisions. It is neither affiliated with nor endorsed by Medtronic, and may violate their Terms of Service. Use of this code is without warranty or formal support of any kind. Try it out and send feedback.
A directory MyDocuments/CareLink/Settings contains a Settings File which is initially blank it will contain information about your pump that is not available from CareLink™.
- Pump AIT
- Insulin Type from drop down List, currently limited to 5 popular pump insulin type open issue it yours is missing and one listed isn't close
- A check box to allow selection of AIT decay algorithm (one uses pump value for 770G only and an advanced one that is based on Insulin Type).
- For MiniMed™ 780G it allows setting you pump Target SG for MiniMed™ 770G its fixed at 120
- Lastly is an area where you can enter your Carb Ratio by time.
