Welcome to you . Here i am designed a Real Time Clock using PIC18F452 microcontroller.I will explain how to design Real Time Clock using PIC microcontroller.RTC Using PIC18F452
PIC is advance microcontroller series. In PIC microcontroller I2C(Inter-Integrated Circuit) Bus is available on board. RTC used in this project is DS1307 which needed I2C interface to read and write data from and to RTC. Because I2C bus is on board in PIC microcontroller Interfacing becomes easy. There will no need to write separate code for I2C bus.
Components Required:
- DS1307
- PIC18F Development board
- breadboard
- connecting wires
- 16×2 LCD
Step 1: Construction
The circuit is designed in two separate parts. Fig. 1 Shows the RTC DS 1307 IC connection. This connection is done by using zero PCB. The connection is same as shown in Fig. 3.
I used PIC18F452 Development Board which i designed few months ago using Screen print technique for pcb design. The SCL pin of RTC is connected to pin 18 and SDA pin is connected to pin 23 of PIC microcontroller. LCD 16×2 is interfaced in following way.
PIN OF LCD PIN OF PIC18F452
- D7 – RD7
- D6 – RD6
- D5 – RD5
- D4 – RD4
- RS – RB5
- RW – RB4
- E – RB3
Step 2: Working Video
Step 3: Code
The code is written in MPLAB IDE and C18 compiler is used to to compiler the code. PICKIT 2 is used to burn the code on PIC18F452 IC. Please read the README file which available in the attachment before proceed.
