First firmware prototype in python is done and all trouble with the libraries is solved.

Currently used libraries:

• micropython-ssd1306
  • https://github.com/stlehmann/micropython-ssd1306

• ina219
  • Inspired by Vantonyan but finished in functionality

Now it is possible to display Voltage, Current and Power on the display.

The measurements are taken every second.

TODO:

• Get rid of sleep functions in the main loop
• Enable button and LED functionality
• Increase font size
• Create pages to show single values in a big font size
• Layout PCB
