Developing embedded applications for Microchip PIC microcontrollers traditionally required physical hardware, debugger probes, and circuit boards. Today, powerful software simulation tools integrated into the development cycle allow engineers to write, debug, and test code entirely on a PC, saving time and hardware costs.
Explain how to set up in the simulator.
You can directly modify register values (e.g., port pins or ADC inputs) during runtime to test how your software handles different scenarios. Microchip Pic Software Simulator
