🚀 Getting Started

ESP32 Firmware

Requirements

• ESP32-S2 DevKit M1
• Arduino IDE (v2.0.17 or compatible)
• USB to UART driver (CP210x from Silicon Labs)
• Required libraries:
  • Wire.h
  • SD.h
  • HardwareSerial.h
  • Arduino.h
  • driver/ledc.h

Setup Instructions

1. Install USB Driver: CP210x VCP Drivers – Silicon Labs
2. Configure Arduino IDE:
   • Add ESP32 board URL:
     https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json
   • Install ESP32 by Espressif Systems (version 2.0.17)
   • Select board: ESP32S2 Dev Module
3. Connect Hardware:
   • SDA (GPIO 14), SCL (GPIO 15), PWM (GPIO 5)
   • Connect AS1170 EVK and required pull-up/down resistors
4. Upload Code and open Serial Monitor (baud rate: 115200)
