Trouble Burning Hex File Into PIC 16F877A Microcontroller

Pritha Ghosh India

Hardware: Ultrasonic Walking Stick Project As Given On Website. Software: MPLAB-X IDE C Language Program

I have been trying to make the Ultrasonic walking stick project as given on your website. I tried burning the hex code into the PIC 16F877A microcontroller using ESA IUP-UXP Intelligent Universal Programmer. But I am not getting any output from the microcontroller. Can you please tell me if there are any memory address changes or any other changes that I need to make? The configuration settings has options for changing ID1,ID2,ID3 and ID4. All of them have been set to 3FFF by default.
I would be very grateful if you could reply back as soon as possible. Thank you.

I have updated the program. Now on startup it beeps several time. This makes sure your hardware is working correctly. Burn the latest hex file and see if the buzzer connected to PB1(PIN 34) pin of MCU beeps or not.

Also post the image of front and back side of your PCB. This will help find any connection errors.
