DaisyGUI

A graphical user interface to the DaisyDriver open-hardware microscope controller.

Features

• Motor control - natural mapped buttons provide tactile interface to the motors
• Preview feed - see where you are on the sample
• Timed image capture - for longer experiments

Current version: 1.03

Documentation in progress. Camera timer appears to be working well but the camera itself struggles with smaller intervals between pictures (approx. 1/2 seconds) for a long period of time (approx. 30 seconds). Taking less pictures at this short interval, or using a longer interval are two possible ways of overcoming this issue.

Requirements

• Raspberry Pi 3B or 3B+ with the latest version of Raspbian Stretch installed
• PiCamera v2
• DaisyDriver

Installation

1. Open terminal window and navigate to the directory you want to install DaisyGUI
2. Enter the command git clone https://github.com/OpenDaisy-Microscopy/DaisyGUI.git
3. Once this has finished, navigate into the DaisyGUI folder using cd DaisyGUI
4. Then run the install script to ensure all required dependencies are installed bash install.sh
5. Now, to open DaisyGUI use the command python3 DaisyGUI.py
6. When opening DaisyGUI subsequently, you will need to navigate to this directory again and run the command in step 5.

To do

• Add capability to split jpg and raw Bayer data immediately after capture
• Improve error handling
• Add support for multiple cameras
• Refactor code for clarity and readability
• Test time for longer periods (weeks)
• Write camera test on load up which uses raspistill to take (and then deletes) a test picture
• Investigate use of video port for long sequences of shorter gap image captures
• Investigate a more robust way of determining serial port (currently just hard-coded)
