Basic introduction and simple engineering application of PIC16F687-E/P

PIC16F687-E/P is a versatile microcontroller chip produced by Microchip Technology, widely used in various embedded applications due to its rich peripheral features and low power consumption.

Introduction:

The PIC16F687-E/P microcontroller belongs to the PIC16F series and is based on the Enhanced Mid-Range 8-bit architecture. It features a high-performance RISC CPU, flash program memory, EEPROM data memory, and a wide range of peripherals, making it suitable for diverse applications in the fields of electronics, robotics, and automation.

Application Scenario:

In a simple project, PIC16F687-E/P can be utilized to build a digital thermometer with temperature sensing and display capabilities. This project will demonstrate how to interface temperature sensors, process analog signals, and drive output devices for temperature indication.

Circuit Design:

To design a digital thermometer using PIC16F687-E/P, follow these steps:

1. Temperature Sensor Connection:

Connect a temperature sensor, such as a thermistor or an LM35, to one of the analog input pins of PIC16F687-E/P, such as pin AN0. Ensure proper signal conditioning, like voltage dividers or amplifiers, to accurately measure the temperature.

2. LCD Display Integration:

Integrate an LCD display module to provide real-time temperature readouts. Connect the data and control lines of the LCD module to the GPIO pins of PIC16F687-E/P, such as PORTB, using appropriate interfacing techniques.

3. Analog-to-Digital Conversion (ADC):

Configure the ADC module of PIC16F687-E/P to convert the analog voltage from the temperature sensor into a digital value. Program the microcontroller to read the ADC result and convert it into temperature units (e.g., Celsius or Fahrenheit).

4. Temperature Display:

Display the temperature readings on the LCD screen in a user-friendly format. Update the display continuously or at regular intervals to provide real-time temperature monitoring.

5. Calibration and Testing:

Calibrate the system by comparing the displayed temperature with a known reference source (e.g., a mercury thermometer). Adjust the firmware algorithms if necessary to improve accuracy. Test the system under different temperature conditions to ensure reliable operation.

Considerations:

When designing the thermometer circuit, consider the following:

- Sensor Selection: Choose a temperature sensor suitable for the application, considering factors like range, accuracy, and response time.

- ADC Resolution: Select an appropriate ADC resolution to achieve the desired temperature measurement accuracy.

- Power Supply: Ensure stable power supply voltage for PIC16F687-E/P and peripherals to prevent malfunctions or inaccuracies.

- Display Interface: Implement proper timing and signaling protocols for interfacing with the LCD display to prevent display artifacts or flickering.

- Firmware Optimization: Write efficient firmware code to minimize power consumption and maximize system responsiveness.

By following these steps and considerations, beginners can build a functional digital thermometer using PIC16F687-E/P and gain hands-on experience in microcontroller-based embedded system design.
