Dimmer

This project creates a dimmer based on an ATTINY85 using PlatformIO.

Features:

• Holding button long will gradually raise and lower power

• Waits on the extremes to make it easier to end up on full and low power

• Has a timeout on max power, will lower power to not overheat

• Short button pushes shuts off, or goes back to last setting
  
  

• SimAVR simulation (MacOS/Windows/Linux, only tested on MacOs/Windows)

  • Installing
    • simavr (brew on Mac, on Windows from https://github.com/maxgerhardt/simavr/releases, apt-get on Linux)
    • SDL2 on host machine (brew on Mac, using MingW pacman on windows, apt-get on Linux)
    • Double-check the paths in the platformio.ini, especially on Windows.
  • Running:
    • First build the .elf: pio run -e attiny85
    • Then run the client: pio run -t exec -e client_windows -vvv or pio run -t exec -e client_macos -vvv
  • Features
    • Takes keypresses as input (try holding down any key)
    • Outputs resulting PWM values and duration in own thread
      • Takes info from memory directly
  • Dumps memory when "m" is pressed to make it easier to find variables
  • Can be much too fast on fast machines, please add pauses inbetween run_avr_for_cycles and/or lessen the number of cycles between pauses

• Unity testing

  • Fails - test/main_test.c not aligned with the source currently
  • assumes very basic testing code with buttons that react
  • however shows how to do create a .vcd file for debugging

TODO:

• Timeout on all light to avoid draining batteries
• Capacitative control (library exists)
