Instructions for Using ATMEGA328P-MU

1. Power Supply:

   • Connect Vcc (pin 7 or 20) to your power source (1.8V to 5.5V).
   • Connect GND (pin 8 or 22) to ground.

2. Clock Configuration:

   • For internal clock, set the fuse bits accordingly.
   • For external clock, connect an external oscillator to XTAL1 (pin 9) and XTAL2 (pin 10).

3. Programming:

   • Use an ISP programmer to upload code to the microcontroller.
   • Connect the programmer to the ISP header (MISO, MOSI, SCK, RESET, Vcc, GND).

4. GPIO Configuration:

   • Configure the direction of I/O pins using the DDRx registers.
   • Set or clear the state of output pins using the PORTx registers.
   • Read the state of input pins using the PINx registers.

5. ADC Configuration:

   • Enable the ADC by setting the ADEN bit in the ADCSRA register.
   • Select the ADC channel using the ADMUX register.
   • Start a conversion by setting the ADSC bit in the ADCSRA register.

6. Timer/Counter Configuration:

   • Configure the prescaler and mode of operation using the TCCRnA and TCCRnB registers.
   • Set the initial value and compare match values using the TCNTn and OCRn registers.

7. Interrupts:

   • Enable global interrupts by setting the I bit in the SREG register.
   • Enable specific interrupts by setting the corresponding bits in the relevant control registers.

8. Serial Communication:

   • Configure the baud rate, data format, and enable the UART by setting the appropriate bits in the UCSRnA and UCSRnB registers.
   • Transmit and receive data using the UDRn register.

9. Watchdog Timer:

   • Enable the watchdog timer by setting the WDE bit in the WDTCSR register.
   • Reset the watchdog timer by writing to the WDTCSR register.

10. Power Management:

    • Use sleep modes to reduce power consumption by setting the SM bits in the MCUCR register.
    • Wake up from sleep modes using external interrupts or watchdog timer.
