[v2.0.0] - 2023-07-17

New v2 codebase

This one has been a long time in the making. We've released our "v2" LED Controller board running an RP2040 processor. This chip is more powerful and more readily available (translation: still being manufactured) than the old Atmega 328P we used on the original boards. This is going to allow more functionality down the road and will be easier to maintain.

However in developing for the new chip, I realized that a lot of my improvements would still work on the v1 Atmega boards, just with some slight tweaks. So with a bit of cleanup and some strategic checks throughout the code, I'm able to maintain a single codebase for both boards.

Changed

  • Improved RC input handling.
    • v2 board uses one core on the RP2040 to read the RC input, so the other core can just focus on running the show
    • v1 board does shorter PWM checks more often, even if it misses some here and there, allowing for more correct show frame timing
  • Added some hysteresis to the knob RC input. When scrolling into a new show, it takes more scrolling to get back out of it, which helps eliminate flickering on boundaries of neighboring shows
  • The "no signal" red flashing doesn't block anymore, so things are way more responsive
  • Layout info is now stored at the end of flash memory. This allows for easy changing of layouts without having to recompile the code, by just adding some data to the end of the compiled .uf2/.hex firmware files, making the web-based Configurator possible
  • Better serial interface. Gives more info, can be controlled with keyboard input, etc.
  • Lots of other tweaks and improvements

[v1.4.2] - 2022-10-26

Fixed

  • Added fallback LED_POWER value so there's always some max power regulation, even if LED_POWER wasn't specified in the layout.h file.

Changed

  • A few Github workflow tweaks

[v1.4.1] - 2022-09-02

Fixed

  • The MAX_BRIGHTNESS code wasn't working due to implicit integer/float issues, causing custom layouts that specified the LED_POWER to end up with a brightness of 0.

[v1.4.0] - 2022-08-21

Support for BME280 chips on new v2 boards has been added. Now the firmware will detect either chip and use it correctly.

This will be the minimum version that the new boards will fully work with, because of the new pressure chip.

[v1.3.1] - 2021-10-08

Added

  • Filtering on RC knob input. We're doing a simple average of a few samples to help clean up jittery RC signals.

Changed

  • The Orange solid color show now uses "DarkOrange" to help it not look so yellow.

Fixed

  • Lots of code optimizations to try and reduce program storage space on the Arduino. Streamlining code, simplifying functions, and removing old sections that are redundant or not in use anymore.

[v1.3.0] - 2021-09-24

New project name and structure

Complete revamp of the whole project structure. The single giant .ino file has been split out into proper .cpp and .h files for better organization.

The project has also been renamed from FT-Night-Radian-LED-Controller to simply LEDController. It's easier to type, and also represents the fact that the controller isn't exclusive to the FT Night Radian anymore.

The existing FT-Night-Radian-LED-Controller repo will be left as-is, and archived with a notice to point people here. While we could have just renamed the old repo, the new project structure would break existing verions of the LEDControllerUpdater app.

Added

  • LED_POWER define for use in layout files. There's a difference in power draw between the Night Radian and the strips we're using for the kits, so this allows us to specify the power draw per LED to keep power usage in check.

[v1.2.4] - 2021-09-02

Changed

  • Auto-adjusting knob input range
    • No more fiddling with throws and endpoints on your radio! Just sweep your transmitter knob to the low and high ends after powering up, and the controller will learn your endpoints.

[v1.2.3] - 2021-03-03

Added

  • TESTMODE define.
    • Uncommenting and setting this define will skip the RC input code, allowing easy testing of new shows without needing a valid RC input.

Changed

  • New MAX_ALTIMETER value and altitude() function.
    • The altitude() function still indicates the current altitude on the wings/fuse like before, but now it will fill up with white LEDs from 0-400ft, and then start filling in reddish/orange LEDs from 400-800ft.

[v1.2.2] - 2020-06-07

Added

  • Added status flash to indicate presence of BMP280 module (mainly for easier testing)

Changed

  • Adjusted RC input upper bounds from 1980us down to 1960us. This should help a bit with those that have needed to adjust radio endpoints to be able to select all shows.

[v1.2.1] - 2020-05-20

Added

  • New RC input status indicators.
    • LEDs flash red when there's no input signal.
    • Once a signal is found, LEDs flash white once for RC input 1, twice for input 2.

Changed

  • MAX_ALTITUDE changed from 400 to 600
  • Toned down flashing for program mode indicators

[v1.2.0] - 2020-05-15

First "official" release.
