Port of arduino-st4 (Kevin Ferrare) to ESP32/PlatformIO with: - FreeRTOS mutex protection at every layer (Pin, Axis, Pulse, Controller) - Hardware timer pulse guiding with ISR-safe deferred stop pattern - Backward-compatible serial protocol (57600 baud, #-terminated) - Extended commands: PULSE, POS?, SYNC, STATUS?, VERSION? - Optional WiFi/WebSocket control (gated by ST4_WIFI_ENABLED) - Dead-reckoning position tracker using esp_timer microsecond precision All 4 examples build clean against esp32dev target.
