Developed a suite of ESP32-based MIDI and touch interface prototypes for the mangtronix/MusicDevices repository, focusing on hardware integration and rapid feature iteration. Over two months, delivered six Arduino and C++ features including multi-point touch sensing, LED feedback, LCD display integration, and analog control for MIDI messages. The work emphasized modular software scaffolding, input smoothing, debouncing, and auto-calibration to support expressive user interfaces. Prototypes included touch-driven MIDI controllers and test sketches for validating touch and display hardware. Code organization and file management were improved for maintainability, with ongoing documentation updates to support future expansion and streamlined development workflows.
December 2024 monthly summary for mangtronix/MusicDevices: Delivered two ESP32-based prototypes to accelerate MIDI hardware integration and touch UI testing. Key features include an ESP32 MIDI Controller Sketch with analog-potentiometer-driven MIDI CC, including ADC smoothing, debouncing, and auto-calibration; and an ESP32 Touch Test with LCD Display to verify touch input, simple readouts, and a visual LED indicator. File naming improvements were applied to improve clarity and maintainability. No major bugs were reported this month; minor refinements and refactors were performed to improve stability and clarity (e.g., renaming ESP32_touch_test_LCD.ino to ESP32_touchTest_fourPads_LCD.ino).

November 2024: Delivered a cohesive prototype suite for ESP32-based touch interfaces in MusicDevices, establishing hardware-ready capabilities and scalable software scaffolding. Implemented four key touch-driven experiences: (1) ESP32 Touch Sensor with LED Feedback for multi-point touch sensing and LED-driven state feedback, with serial diagnostics and future LCD integration placeholder; (2) Touch Sensor MIDI Controller with LCD Display featuring improved MIDI mapping and touch input handling, plus scaffolding and documentation; (3) ESP32 Touch Test with LCD Display providing test sketches for touch inputs, LCD initialization, and serial debugging; and (4) 3-Button MIDI Controller with Analog CC and Debounced Buttons enabling smooth CC and note mappings, input smoothing, and auto-calibration. These efforts provide a solid foundation for expanded hardware interfaces and faster iteration cycles, while enhancing developer productivity and end-user expressiveness.”,
