Resistor calculator

A simple app to calculate resistor values from the coloured bands, based on original work by Lewis Westbury.

• Pick from 3, 4, 5, or 6 band resistor.
• Left and right to move the current focus, up and down to adjust the coloured bands.
• Resistance, tolerance, and temperature coefficient are updated instantly.
• This version shows friendly resistance values, supports Pink color bands, and adds three missing Temp Coefficients (+-1, +-20, +-250).

Requirements

This app is tested against the current dev and release branches of the OFW:

• Current OFW Version: 1.2.0
  

Build

These apps are built using ufbt - a subset of the flipper build tool (fbt) targeted at building apps. Install it with:

pip install ufbt

For build only, run ufbt from the terminal in the project directory. To upload, make sure Flipper is connected to your computer and run ufbt launch.

The directory contains the following batch script(s) to simplify the upload process:

• win_launch.bat - Windows only. Invokes ufbt to deploy and launch the app on a flipper over USB, and resets terminal colors in case of error.

Build outputs are found in the dist directory for each application.
