[ATmega4809 Curiosity Nano Review] Software Simulation [Copy link]

Software simulation is a common method in program development. It can reduce the loss of the internal flash of the microcontroller without frequent downloading of programs to the microcontroller. It can also be used without hardware to speed up development.

In MPLAB X IDE, the software simulation is set by selecting simulator in Hardware Tool in the following properties.

During software simulation, the computer's CPU is used to simulate the operation of the microcontroller, so the simulation speed depends on the speed of the computer. In addition, some functions that depend on hardware cannot be implemented through software simulation.

Another benefit of software simulation is that you can view the running time, which is not available on most low-cost hardware emulators. To use this function, first set the running speed in the project properties:

Then enter simulation mode and select StopWatch from the Windows menu in MPLAB X IDE.

Set breakpoints in the source program, run the program, and then you can observe the running time.
