Pattern Studio reaches 1.0.0.
Pattern Studio is now the main way to program animations on HitLib-controlled strips. From here on, every new HitLib feature ships in Pattern Studio too. Hand-writing animation code is still there, but it's the opt-out, not the default.
Colors that track your robot, live
A strand can fill like a gauge, tracking a motor's heat, an arm's rotation, or the battery, entirely on its own, with nothing in your control loop watching it. Split one strand into several independent gauges: a strip under the drivebase can show all six drive motors' temperatures at once, each segment colored by its own reading.
One strand, six independent gauges: each segment is one drive motor's temperature.
What HitLib actually does
Three parts work together: a library that runs on the robot, an editor that builds the animations, and a physical kit that lights up. Here's what each one is for.
HitLib
A PROS-based C++ library that drives WS2812B strips over a VEX V5 Brain's ADI ports. Compose animations like flow, rainbow, pulse, flash, twinkle, bitscroll, and center-spread into named, prioritized modes, or let a strand fill like a gauge that tracks a motor's heat, an arm's rotation, or the battery on its own.
Pattern Studio
A desktop app that designs those looks against a live preview, then exports them as a ready-to-include C++ header. Drop a song into the Song bar and it bakes the track's loudness into a table your strip fills to as it plays. Hand-writing code is still there as an opt-out.
LED Kits
Physical strip and wiring kits from the team, built to plug straight into a VEX Brain. Test kits are already running, and general kits are open for order now.

HitLib is the PROS-based library that drives WS2812B strips off a VEX V5 Brain's ADI ports, with animations like flow, rainbow, pulse, flash, twinkle, bitscroll, and center-spread composed into named, prioritized modes you switch at runtime. Pattern Studio sits alongside it as external software you install once, so you can preview and build any of that live, then export it as ready-to-include C++. No round-trip through code is required unless you want one.
- Design against a live preview, then export straight to a ready-to-include C++ header.
- Drag your PROS project onto the window and Deploy writes that header into
include/. - Drop a song into the Song bar (MP3, M4A, FLAC, OGG, WAV, or MIDI) and the strip fills to its loudness as it plays.
- Pick an animation such as Rainbow or Twinkle, then tune its speed and palette.
- Splice Mask splits a strand into sections you can invert or alternate for layered effects.
- Select multiple strands and group-edit them as a single animation.
- Writing animation code by hand is still fully supported as an opt-out.
