PedalinoMini Phoenix is a significant evolution of the original PedalinoMini™, bringing modern features, improved usability, and enhanced performance to this wireless MIDI foot controller for musicians.
- Expanded Connectivity: Supports up to 15 inputs, allowing a flexible combination of footswitches and expression pedals.
- Enhanced UI: Dark mode enabled by default with a Phoenix-themed color scheme featuring orange highlights.
- Improved Profile System: Easily switch between profiles with color-coded LED indicators.
- Better User Experience: Redesigned homepage with a card-based layout displaying system status at a glance.
- Simplified Setup: Preconfigured credentials and default settings make initial setup quick and easy.
- Visual Enhancements: New LED effects and animations provide clear system status feedback.
- Optimized Display Performance: Fixed SSD1306 OLED display glitches on ESP32 through advanced multi-core task scheduling and cooperative yielding between display and MIDI operations.
- Comprehensive Documentation: Organized and accessible docs using mkdocs.
This refresh retains the core functionality that made the original PedalinoMini popular while adding modern touches and quality-of-life improvements for performers.
- Board Support: Optimized for ESP32 DevKit V1. Other ESP32 boards may work but are not officially tested.
- USB MIDI: Officially tested with Arduino ProMicro. Other implementations may work but aren't guaranteed.
- Removed Features: Pedal types requiring 2 GPIO pins (e.g., rotary encoders, ultrasonic sensors) have been removed to enable the new 15-pedal mode, where each pedal uses a single GPIO.
- Simplified Input Types: Focused on the most common types: momentary switches, latches, analog pedals, and analog pads.
