🚀 MicroTaskX v3.1.0 — Advanced Control Utilities & Display Optimizations
We are excited to announce the release of MicroTaskX v3.1.0! This version introduces a major overhaul to MTXUtils, transforming it from basic utility functions into a robust, standalone toolset for embedded systems, advanced robotics, automation, and high-performance UI rendering.
This update maintains complete separation of concerns, keeping MTXUtils completely decoupled from the core MicroTaskXKernel scheduler.
🌟 What's New in v3.1.0

  1. 🎮 Advanced Control Systems
    Anti-Windup PID Controller (computePID): Implement closed-loop control for motors, heaters, or balancing robots safely with integrated integral windup prevention.
    Hysteresis Logic (applyHysteresis): Protect physical relays and hardware components from rapid oscillation near threshold limits.
  2. ⚡ High-Speed LCD Drawing & Visual Aesthetics
    Flicker-Free Screen Updates (updateScreenSmart): A template-driven differential buffer update that modifies only changed characters on LiquidCrystal / I2C displays, drastically reducing drawing overhead and eliminating annoying screen flashes.
    Non-Blocking Typewriter Effect (printTypewriter): Smooth, cinematic text scrolling without blocking the main loop or tasks.
    Centered Output Calculator (getCenterOffset): Automatic string centering based on your display's columns.
    Visual Progress Bar Generator (getProgressBarString): Instantly render text-based progress bars (e.g., [===== ]).
  3. 📊 Signal Filtering & Data Buffering
    True Moving Average Filter (movingAverage): A sliding-window filter to suppress extreme analog noise.
    Generic Circular Queue Class (MTXCircularQueue): High-speed, lock-free ring buffer template for smooth hardware communication (e.g., Serial/UART streams).
    Signal Edge Detection (isRisingEdge/isFallingEdge): Low-overhead state change monitoring.
  4. 🧮 Data Integrity & System Metrics
    Dallas/Maxim CRC8 Checksum (computeCRC8): Verify data packets across wireless modules or storage without standard library overhead.
    Battery Level Calculator (calculateBatteryPercentage): Hardware-aware voltage scaling using analog pins and resistor dividers.
    Time & Hex Formatters: Built-in formatMillisToTime (HH:MM:SS) and byte-to-hex utility conversions.
    🛠 File Changes & Structural Updates
    MTXUtils.h: Upgraded with template structures, MTXButton encapsulation fix, and advanced hardware management methods.
    MTXUtils.cpp: Implementation of standard mathematical and logic controllers.
    library.json & library.properties: Bumped version metadata to 3.1.0 and appended new control/timing keywords.
    💻 Quick Usage Example
#include <MicroTaskX.h>
#include <LiquidCrystal_I2C.h>

LiquidCrystal_I2C lcd(0x27, 16, 2);

char currentFrame[2][17] = {"                ", "                "};
char memoryFrame[2][17]  = {"                ", "                "};
MTXPID speedPID = { 2.5, 0.5, 0.1, 0, 0, 0, 255 }; 

void setup() {
  lcd.init();
}

void loop() {
  // 1. Smooth PID calculation
  float motorPWM = MTXUtils::computePID(100.0, readEncoder(), speedPID, 0.01);
  
  // 2. Flicker-free UI Rendering
  sprintf(currentFrame[0], "PWM Out: %03d    ", (int)motorPWM);
  MTXUtils::getProgressBarString(16, (motorPWM/255)*100, currentFrame[1]);
  
  MTXUtils::updateScreenSmart<16, 2>(lcd, currentFrame, memoryFrame);
}
