mikroC Working Environment

The mikroC Integrated Development Environment (IDE) is designed for writing and compiling C code for various PIC microcontrollers. Here is a brief overview of its key features:

1. Code Editor: Write and manage your C code here.
   

2. Project Manager: Organize your files and projects in the Project Manager window.
   

3. Compiler: Click on the "Build" button to compile your code and generate the HEX file.
   

4. Library Manager: Access ready-to-use libraries for various peripherals such as LCD, I2C, and UART.
   

Once the code is written, the mikroC compiler converts it into a HEX file, which can be loaded into the PIC microcontroller using the PICKIT2 Programmer or simulated in Proteus.

Proteus Working Environment

Proteus Design Suite is a powerful tool used to simulate circuits and embedded systems. It allows you to test your microcontroller-based designs virtually before implementing them on hardware.

Key Features:

• Schematic Capture: Design circuits using the Schematic Capture interface.
• Component Library: Select components like PIC16F877A, LCD, LEDs, etc., from the vast library.
• Microcontroller Simulation: Load the HEX file generated from mikroC into Proteus for testing.
• Virtual Oscilloscope & Debugging Tools: Use built-in tools to troubleshoot your circuits.

By using Proteus, you can design, simulate, and test circuits before physical prototyping and visualize how each project functions in real-time.
