I need someone to write a code for a PIC based project. The project consists of a sensor(interrupt based), 4x4 keypad, seven segment display, and a relay. MCU Used: PIC16F877A Software to be used: MPLAB X IDE

Job ID: 33622908

Budget: ₹1,500 – ₹12,500 INR

It's a device that counts objects that passes by. Pressing the start button on the 4x4 keypad will start the counting of objects. Every time the interrupt is triggered(falling edge), the count should increase by one and should be displayed on a 5 digit seven segment display.
There are a few modes that I'll explain on chat, but these are the major tasks.
I have the hardware with me, so project will be completed after I get the satisfactory output on hardware.
Deliverables will be the MPLAB .X file.
I know how to use Arduino IDE for AVRs, so I know that logic isn't that difficult, I only need someone who has experience with PIC to save time setting the register values and stuff.
