Instructions for Use:
Power Supply:
- Connect Vdd (pin 40) to the positive supply voltage (2.0V to 5.5V).
- Connect Vss (pin 20) to ground.
Oscillator Configuration:
- For an external crystal oscillator, connect the crystal between OSC1 (pin 13) and OSC2 (pin 14).
- For an internal oscillator, configure the configuration bits to select the desired internal clock source.
Programming:
- Use the ICSP interface (MCLR, PGD, PGC pins) for in-circuit serial programming.
- Ensure the MCLR pin is connected to a high-voltage programmer for high-voltage programming or to a low-voltage programmer for low-voltage programming.
Reset:
- The MCLR pin can be used as a reset input. Pull it low to reset the microcontroller.
- Enable the Brown-out Reset (BOR) feature in the configuration bits to protect against low-voltage conditions.
Analog-to-Digital Converter (ADC):
- Configure the ADC module using the ADCON0, ADCON1, and ADCON2 registers.
- Select the appropriate analog input channel and start the conversion.
Timers:
- Configure the timers (Timer0, Timer1, Timer2) using the respective control registers (T0CON, T1CON, T2CON).
- Set the prescaler and enable interrupts if needed.
Interrupts:
- Enable global interrupts by setting the GIE bit in the INTCON register.
- Enable specific interrupt sources by setting the corresponding bits in the PIE1 and PIE2 registers.
Serial Communication:
- Configure the USART module for serial communication using the BAUDCON, TXSTA, and RCSTA registers.
- Use the SPI and I2C modules for serial peripheral interfaces by configuring the SSPCON and SSPSTAT registers.
Power Management:
- Use the SLEEP instruction to enter sleep mode and reduce power consumption.
- Wake up from sleep mode using an interrupt or a reset.
Watchdog Timer (WDT):
- Enable the WDT in the configuration bits to prevent the microcontroller from getting stuck in an infinite loop.
- Clear the WDT periodically to prevent a reset.
