This project demonstrates the ADC (Analog-to-Digital Converter) functionality of the STC8G series microcontroller (like STC8G1K17 - STC8G1K08) using a 10K potentiometer and SSD1306 OLED display. The analog voltage from the potentiometer is converted to digital values and displayed in numerical form on the OLED screen.
- Read analog voltage from 10K potentiometer via ADC
- Display raw ADC value (0-1023)
- Compatible with STC8G1K17 (8051 core)
- Uses I²C communication for SSD1306 OLED

The STC8G series is based on enhanced 8051 architecture with:
- Single-cycle 8051 core (faster than traditional 8051)
- Integrated 10-bit ADC
- Multiple power modes
- Enhanced peripherals while maintaining 8051 instruction set compatibility
- 10-bit resolution
- Multiple channel support
- Internal reference voltage option
- High conversion speed
- Compiler: SDCC (Small Device C Compiler) for 8051
- IDE: Code::Blocks
- ISP: STC-ISP
Note: This project is specifically designed for 8051-architecture STC8G microcontrollers. The code may need adjustments for other 8051 variants or different architectures.
