📖 How to Use
🎯 Getting Started
This tool helps you configure microcontroller registers from datasheets:
- Select Microcontroller: Choose Arduino Uno/Nano or Mega
- Choose Register: Select from GPIO, Timer, USART, ADC, or Interrupt registers
- Click Bits: Toggle bits on/off to configure the register
- See Explanations: Each bit shows what it controls
- Get Code: Copy Arduino/C code to use in your project
⚡ Register Types
- GPIO (DDRx, PORTx, PINx): Configure pin direction, output state, and read input
- Timer/Counter: Configure PWM, prescalers, compare modes
- USART: Set baud rate, parity, stop bits, enable TX/RX
- ADC: Configure analog-to-digital converter settings
- Interrupts: Enable/disable timer and peripheral interrupts
🔧 Common Workflows
- Configure Output Pin: DDRB |= (1<
- Set PWM: Use Timer registers (TCCR1A, TCCR1B) for PWM mode
- Enable Serial: Configure UCSR0B to enable TX/RX
- Read ADC: Set ADMUX for reference and channel, ADCSRA to start
📝 Quick Tips
- Hover over bit names to see detailed descriptions
- Red labels indicate reserved or unused bits
- Use the code output to integrate into your Arduino sketches
- Refer to datasheet for complete register documentation
