 # Universal Optical 2-Channel Angle Gauge / Tachometer
 
-## Tested on
+## Features
 
-1. [ESP32 ESP-IDF v5.5.3](https://docs.espressif.com/projects/esp-idf/en/v5.5.3/esp32/index.html)
+1. Two independent measuring channels for optical encoders with 3600 pulses per revolution.
+2. Four operating modes selected through the on-device menu: angle/angle, tacho/tacho, angle/tacho and remote.
+3. Angle measurement with 0.1 degree resolution and resettable current angle value.
+4. Rotational speed measurement in RPM with 100 ms refresh period.
+5. 16x2 LCD display on PCF8574 I2C expander with boot animation, progress bar and live value updates.
+6. Rotary encoder menu for mode switching and push-button long press for angle reset.
+7. WiFi access point and station modes running simultaneously.
+8. Over-the-Air firmware updates through the built-in web server with rollback self-check.
+9. Remote syslog logging of task stack usage and driver error counters after station connection.
+10. FreeRTOS multitasking with separate tasks for each channel, encoder, LCD expander and statistics.
 
-## SAST Tools
+## Attention
 
-[PVS-Studio](https://pvs-studio.com/pvs-studio/?utm_source=website&utm_medium=github&utm_campaign=open_source) - static analyzer for C, C++, C#, and Java code.
+1. Remote mode via ESP-NOW is not implemented yet.
+2. WiFi station credentials are hardcoded in the firmware configuration.
+3. Long press of the encoder button resets the angle value, short press switches the menu mode.
+4. The GPIO pin mapping matches the ATE0005 board connectors and must not be changed without a hardware revision.
