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.

// ST4-ESP32 Pulse Guide Example
|
|
// Demonstrates hardware-timer pulse guiding with position tracking
|
|
//
|
|
// Send via serial (57600 baud):
|
|
// CONNECT# - connect to mount
|
|
// PULSE RA+ 500# - pulse RA+ for 500ms
|
|
// PULSE DEC- 1000# - pulse DEC- for 1 second
|
|
// POS?# - read current position
|
|
// STATUS?# - full status report
