-1. Support up to 4 touch pads on one device (depends on the used ESP32 chip).
-2. Support 8 or 16 pad work mode.
+1. Support for 8-pad and 16-pad TTP229 configurations.
+2. RMT-based SPI-like communication without GPIO bit-banging.
+3. Multi-device support with unique device numbering.
+4. FreeRTOS task for debouncing and event dispatching.
+5. Error statistics tracking (RMT driver, event post, queue overflow, stack).
+6. Event-based API via esp_event framework.
+7. IRAM-safe ISR handler and RMT callback.
